Influence of Human Activity Intensity on Habitat Quality in Hainan Tropical Rainforest National Park,China

Due to long-term human activity interference,the Hainan Tropical Rainforest National Park(HTRNP)of China has experienced ecological problems such as habitat fragmentation and biodiversity loss,and with the expanding scope and intensity of human activity impact,the regional ecological security is facing serious challenges.A scientific assessment of the interrelationship between human activity intensity and habitat quality in the HTRNP is a prerequisite for achieving effective management of ecological disturbances caused by human activities and can also provide scientific strategies for the sustainable development of the region.Based on the land use change data in 2000,2010,and 2020,the spatial and temporal variations and the relationship between habitat quality(HQ)and human activity intensity(HAI)in the HTRNP were explored using the integrated valuation of ecosystem services and trade-offs(InVEST)model.System dynamics and land use simulation models were also combined to conduct multi-scenario simulations of their relationships.The results showed that during 2000–2020,the habitat quality of the HTRNP improved,the intensity of human activities decreased each year,and there was a negative correlation between the two.Second,the system dynamic model could be well coupled with the land use simulation model by combining socio-economic and natural factors.The simulation scenarios of the coupling model showed that the harmonious development(HD)scenario is effective in curbing the increasing trend of human activity intensity and decreasing trend of habitat quality,with a weaker trade-off between the two compared with the baseline development(BD)and investment priority oriented(IPO)scenarios.To maintain the authenticity and integrity of the HTRNP,effective measures such as ecological corridor construction,ecological restoration,and the implementation of ecological compensation policies need to be strengthened.

Sustainable Intensification and Large-scale Operation of Cultivated Land Use at the Farmers’ Scale:A Case Study of Shandong Province,China

Sustainable intensification of cultivated land use(SICLU) and large-scale operations(LSO) are widely acknowledged strategies for enhancing agricultural performance.However,the existing literature has faced challenges in precisely defining SICLU and constructing comprehensive indicators,which has hindered the exploration of factors influencing LSO within the SICLU framework.To address this gap,we integrated self-efficacy theory into the design of an index framework for evaluating SICLU.We subsequently employed econometric models to analyze the significant factors that impact LSO.Our findings reveal that SICLU can be divided into four key dimensions:intensive management,efficient output,resource conservation,and ecological environment optimization.Furthermore,it is crucial to incorporate belief-based cognitive factors into the index system,as farmers’ understanding of fertilizer and pesticide application significantly influences their willingness to engage in LSO.Moreover,we identify grain market turnover as the most influential factor in promoting LSO,with single-factor contribution rates reaching 70.9% for cultivated land transfer willingness and 62.5% for the total planting areas.Interestingly,unlike irrigation and agricultural machinery inputs,increased labor inputs correspond to larger planting areas for farmers.This trend may be attributed to reduced labor availability because of rural labor migration,whereas the reduction in irrigation and agricultural input is contingent on innovations in production practices and the transfer of cultivated land management rights.Importantly,SICLU dynamically influences LSO,with each index related to SICLU having an optimal range that fosters LSO.These insights offer valuable guidance for policymakers,emphasizing farmers as their central focus,with the adjustment of input and output factors as a means to achieve LSO as the ultimate goal.In conclusion,we propose research avenues for further enriching the SICLU framework to ensure that it aligns with the specific characteristics of regional agricultural development.

New Rural Community Construction or Retention Development:A Comparative Analysis of Rural Settlement Transition Mechanism in Plain Agriculture Area of China Based on Actor Network Theory

It is an important way to realize rural revitalization and sustainable development to guide rural settlement transition(RST)in an appropriate way.This paper uses actor network theory(ANT)to construct a theoretical framework for the study of RST.Taking two typical villages with different transition paths in rural areas of North China Plain as examples,this paper reveals the mechanism of RST and makes a comparative analysis.The results show that:1)after identifying problems and obligatory passage point,key actors recruit heterogeneous actors into the actor network by entrusting them with common interests,and realize RST under the system operation.2)Rural settlements under different transition paths have similarities in the problems to be solved,collective actions and policy factors,but there are differences in the transition process,mechanism and effect.The actor network and mechanism of RST through the path of new rural community construction are more complex and the transition effect is more thorough.In contrast,the degree of RST of retention development path is limited if there is no resource and location advantage.3)Based on the applicable conditions of different paths,this paper designs a logical framework of‘Situation-Structure-Behavior-Result’to scientifically guide the identification of RST paths under the background of rural revitalization.

Impact of the carbon market on investment benefits of power-grid enterprises in China: a system dynamics analysis

The power grid,as the hub connecting the power supply and consumption sides,plays an important role in achieving carbon neutrality in China.In emerging carbon markets,assessing the investment benefits of power-grid enterprises is essential.Thus,studying the impact of the carbon market on the investment and operation of powergrid enterprises is key to ensuring their efficient operation.Notably,few studies have examined the interaction between the carbon and electricity markets using system dynamics models,highlighting a research gap in this area.This study investigates the impact of the carbon market on the investment of power-grid enterprises using a novel evaluation system based on a system dynamics model that considers carbon-emissions from an established carbon-emission accounting model.First,an index system for benefit evaluation was constructed from six aspects:financing ability,economic benefit,reliability,social responsibility,user satisfaction,and carbon-emissions.A system dynamics model was then developed to reflect the causal feedback relationship between the impact of the carbon market on the investment and operation of power-grid enterprises.The simulation results of a provincial power-grid enterprise analyze comprehensive investment evaluation benefits over a 10-year period and the impact of carbon emissions on the investment and operation of power-grid enterprises.This study provides guidelines for the benign development of power-grid enterprises within the context of the carbon market.

An Experimental Study on the Effectiveness of Individualized Online Intervention for Mental Health Literacy of Community Residents

Background:Understanding how to improve mental health literacy is conducive to maintaining and promoting individuals’mental health and well-being.However,to date,interventions for mental health literacy primarily depend on traditional education and contact interventions,which have limitations with regard to pertinence and individualization.Artificial intelligence(AI)and big data technology have influenced mental health services to be more intellectual and digital,and they also provide greater technical convenience for individualized interventions for promoting mental health literacy.However,there is relatively little research on the effectiveness of individualized online intervention for mental health literacy in the literature.This study aims to fill this void.To verify whether individualized online intervention can improve the level of mental health literacy.Methods:We conducted a pretest–post-test control experiment.The participants were recruited from a large community located in central China.A total of 152 participants completed the research.We use mixed linear model estimation and paired t-tests to analyze the data.Results:Individualized online intervention can effectively improve the mental health literacy level of participants.Specifically,we found that compared with the control group,the mental health literacy in the experimental group was significantly improved after receiving individualized online intervention.Likewise,the mental health literacy of the control group has also improved after receiving individualized online intervention.In addition,we compared the mental health literacy level of the experimental group at Time 3 to those at Time 2 and found that the mental health literacy level at Time 3 had not decreased one month later.This shows that individualized online intervention was not only momentarily effective,but also had long-term efficacy.Conclusion:This study illustrates that the individualized online intervention has both great momentary and long-term effectiveness in improving community residents’mental health literacy.

Migration and Spatiotemporal Land Cover Change: A Case of Bosomtwe Lake Basin, Ghana

Internal migration is highly valued due to its increasingly acknowledged potential for social and economic development. However, despite its significant contribution to the development of towns and cities, it has led to the deterioration of many ecosystems globally. Lake Bosomtwe, a natural Lake in Ghana and one of the six major meteoritic lakes in the world is affected by land cover changes caused by the rising effects of migration, population expansion, and urbanization, owing to the development of tourist facilities on the lakeshore. This study investigated land cover change trajectories using a post-classification comparison approach and identified the factors influencing alteration in the Lake Bosomtwe Basin. Using Landsat imagery, an integrated approach of remote sensing, geographical information systems (GIS), and statistical analysis was successfully employed to analyze the land cover change of the basin. The findings show that over the 17 years, the basin’s forest cover decreased significantly by 16.02%, indicating that population expansion significantly affects changes in land cover. Ultimately, this study will raise the awareness of stakeholders, decision-makers, policy-makers, government, and non-governmental agencies to evaluate land use development patterns, optimize land use structures, and provide a reference for the formulation of sustainable development policies to promote the sustainable development of the ecological environment.

From Control to Empowerment:A Paradigm Shift in the Discourse of Educational Supervision

As educational reforms intensify and societal emphasis shifts towards empowerment,the traditional discourse paradigm of management and control in educational supervision faces growing challenges.This paper explores the transformation of this discourse paradigm through the lens of empowerment,analyzing its distinct characteristics,potential pathways,and effective strategies.This paper begins by reviewing the concept of empowerment and examining the current research landscape surrounding the discourse paradigm in educational supervision.Subsequently,we conduct a comparative analysis of the“control”and“empowerment”paradigms,highlighting their essential differences.This analysis illuminates the key characteristics of an empowerment-oriented approach to educational supervision,particularly its emphasis on dialogue,collaboration,participation,and,crucially,empowerment itself.Ultimately,this research advocates for a shift in educational supervision towards an empowerment-oriented discourse system.This entails a multi-pronged approach:transforming ingrained beliefs,embracing renewed pedagogical concepts,fostering methodological innovation,and optimizing existing mechanisms and strategies within educational supervision.These changes are proposed to facilitate the more effective alignment of educational supervision with the pursuit of high-quality education.

Ideas and Countermeasures for Perfecting Rural Public Product Supply from the Perspective of Main Beneficiaries

On the basis of defining the concept of rural public product supply, the weaknesses of the supply mechanism of rural public product are analyzed. The shortages of rural public product supply lead to the difficult ties in developing agriculture and rural economy; enriching farmers and narrowing the urban and rural income gap. Problems in rural public product supply are further analyzed. Firstly, the national finance used in agriculture is low. Secondly, farmers are not separated from decision system and the beneficiaries separate from the decision-makers. Thirdly, farmers are not fully treated as civilians. Fourthly, rural areas lack the selection and supervision mechanism of public product. The ideas and countermeasures on perfecting rural public product are put forward from the perspective of main beneficiaries. The supply of rural public product should take intensifying the self development capability of farmers as core; farmers should actively participate in the making the rural public product decision and fight for their right to say. Farmers should unit together through organizations to improve the organizational level. Farmers should actively participate in trainings on them and try to get the updated information from the local government. The village collective should protect the supply of rural public product.

Trade-off and Synergy of Rural Functions Under County Depopulation in the Typical Black Soil Region of Northeast China

As the population continues to shrink in the black soil region of Northeast China since 2000,it is critical to master the impact of population shrinkage on rural functions to realize rural revitalization and sustainable development.In this study,we focused on the impacts of depopulation on the evolution and interrelationship of rural subfunctions.Based on the rural function indexes system,the TOPSIS(Technique for Order Preference by Similarity to an Ideal Solution)method,spatial analysis method,and mathematical statistics analysis method were used to summarize the spatial and temporal characteristics of rural function development,as well as the effect of population shrinkage in the typical black soil region of Northeast China.The results showed that depopulation varied in the extent and duration between the forested region and plain areas,which both impacted the trajectories of rural subfunctions evolution.For the economic development function and ecological conservation function,the effect of continuous slight depopulation was beneficial,while the effect of rapid depopulation was adverse,which was exactly opposite to the agricultural production function.All forms of population shrinkage were conducive to the development of the social security function.With the deepening population shrinkage,depopulation mainly promoted the collaborative development between subfunctions in this study,except the relationship between agricultural production and social security function.But effects of depopulation on the interrelationship of rural subfunctions varied between the forested region and plain areas in some cases.The results provided evidence for the cognition that population shrinkage had complicated effects on rural subfunctions.

Untangling the increasing elevation of cropland in China from 1980 to 2020

The redistribution of cropland to areas of higher elevation in China has long affected agricultural development and could seriously threaten national food security.However,there is currently little research reported on this phenomenon,which may limit the improvement of cropland protection policies.To fill this gap,we analyzed the spatiotemporal characteristics and driving mechanisms of increased cropland elevation in China during the period 1980-2020.The average cropland elevation in China increased by 17.38 m from 1980 to 2020.The gravity center of the cropland area and average cropland elevation in China moved to the northwest by 81.00 km and 51.47 km,respectively.The amount of newly added cropland in eastern China was less than that in occupied regions;however,the average elevation of newly added cropland was greater than that of occupied cropland,though the opposite phenomenon was observed in western China.Slope,temperature,land-use intensity,population,economic density,and distance to main roads were the main factors affecting the redistribution of cropland to areas of higher elevation.The effects of these major driving factors exhibited significant spatial and temporal variations in China.This study has important implications for improving existing cropland protection policies and developing more effective cropland management systems in China.

Spatio-temporal Evolution of the Rural Regional System and Its Evolution Mechanism in Huang-Huai-Hai Area of China

The problem of rural development arises from the evolution of rural regional system.It is urgent to deepen the research on the evolution process and mechanism of rural regional system.However,there are relatively few studies on rural development from the perspective of the evolution process,driving mechanism and evolution mechanism of rural regional system.Therefore,this study took Huang-Huai-Hai Area for example,started with the systematicness of the rural regional system,the spatio-temporal pattern and driving mechanism of rural regional system evolution,and further summarized and refined the evolution mechanism of the rural regional system.The methods of spatial pattern analysis,gray correlation degree and geographical detection were adopted.The results showed that the problems in rural areas were often dominated by one factor and produced by the joint action of many factors.Factors such as county urbanization,county economy,county public service,agricultural mechanization,surrounding cities and convenient transportation will affect the evolution of rural regional systems.Based on the evolution of the elements in the rural regional system,the evolution types of rural regional system can be divided into decline type,equilibrium type and growth type.This study can provide a reference for understanding the process of rural rise and fall and can also guide rural revitalization and rural sustainable development.

A review of monitoring,calculation,and simulation methods for ground subsidence induced by coal mining

Subsidence data acquisition methods are crucial to mining subsidence research and an essential component of achieving the goal of environmentally friendly coal mining.The origin and history of the existing methods of field monitoring,calcula-tion,and simulation were introduced.It summarized and analyzed the main applications,flaws and solutions,and improve-ments of these methods.Based on this analysis,the future developing directions of subsidence data acquisition methods were prospected and suggested.The subsidence monitoring methods have evolved from conventional ground monitoring to combined methods involving ground-based,space-based,and air-based measurements.While the conventional methods are mature in technology and reliable in accuracy,emerging remote sensing technologies have obvious advantages in terms of reducing field workload and increasing data coverage.However,these remote sensing methods require further technological development to be more suitable for monitoring mining subsidence.The existing subsidence calculation methods have been applied to various geological and mining conditions,and many improvements have already been made.In the future,more attention should be paid to unifying the studies of calculation methods and mechanical principles.The simulation methods are quite dependent on the similarity of the model to the site conditions and are generally used as an auxiliary data source for subsidence studies.The cross-disciplinary studies between subsidence data acquisition methods and other technologies should be given serious consideration,as they can be expected to lead to breakthroughs in areas such as theories,devices,software,and other aspects.

Does innovative city pilot policy promote urban green growth in China?An analysis of green total factor productivity,2005-2020

The innovative city pilot policy(ICPP)is an essential manifestation of China’s construction of an innovative and green-driven development country.We incorporated urban green total factor productivity(GTFP)growth into the evaluation of ICPP.Based on the panel data of 223 cities in China from 2005 to 2020,we used the difference-in-differences model to empirically assess the influence and mechanism of the ICPP on urban GTFP growth.The main results show that(i)The ICPP has maintained an effectively fluctuating promotion on urban GTFP growth,mainly manifested in the urban green technological progress improvement.(ii)The ICPP has urban heterogeneity in promoting GTFP growth in pilot cities,mainly affecting key cities such as provincial capitals.(iii)The interaction between the agglomeration of producer services and the ICPP inhibits GTFP growth in pilot cities.

Influence Mechanism of New-type Urbanization on Urban Land Use Efficiency in the Yangtze River Delta, China

Rapid urbanization in China has led to inefficient use of urban land and spatial structure disorder,attracting attention from academia and society.Taking the Yangtze River Delta,China as an example,this study constructed an index evaluation system that quantitatively analyses the impact of new-type urbanization(NTU)on urban land use efficiency(ULUE)from 2000 to 2020 using a panel data vector autoregressive model.The results show that NTU in the Yangtze River Delta promotes ULUE improvement.However,the promotion of NTU to ULUE is limited,and the level of urban economic development also plays a role in promoting the change of ULUE.Moreover,the study further analyzed the results of urbanization decomposition and found that population urbanization(PU),economic urbanization(EU),spatial urbanization(SU),and social urbanization(SCU)can explain changes in ULUE in the Yangtze River Delta to a certain extent.In terms of variance decomposition,PU contributed the most to ULUE,followed by EU,SU,and SCU.Some necessary measures should be taken to coordinate the development of different types of urbanization,improve the sustainable utilization level of land resources,and provide a reference for high-quality development in the Yangtze River Delta.

Spatial-temporal Coupling Analysis of Economic Development-Social Development-Government Governance in Xinjiang, China

High-quality development of ethnic minority areas is a key issue in China’s economic and social transformation.In order to explore the development trend and optimization path of high-quality development in ethnic minority areas,this study constructed a systematic evaluation index system of economic development,social development and government governance.The coupled coordination model was adopted to quantitatively analyze the spatio-temporal evolution characteristics of economic development,social development and government governance in Xinjiang from 2013 to 2020.The influencing factors of coupling coordination development of the three systems were identified by grey correlation analysis.The spatial-temporal pattern analysis results show that the coupling coordination degree of Xinjiang increased steadily,but the regional differences gradually expanded.The coupling coordination degree shows a stable structure with high center and low periphery,and a spatial pattern of low in southern Xinjiang and high in northern Xinjiang.The results of grey correlation analysis show that the grey correlation degree among economic development,social development and government governance in Xinjiang is above 0.78.The three systems of economic development,social development and government governance interact with each other,forming a complex system of high-quality development in ethnic minority areas.To promote highquality development in Xinjiang,it should take social stability and long-term stability as the overall goal,improve the quality of the production and living environment on the basis of economic development,enhance regional economic competitiveness,and take government governance as a means to optimize the environment for regional development.

Historical Evolution and Innovation of Supply of Rural Public Cultural Service in China

Based on the analysis of main body,decision making and financing mode concerning the supply of public cultural services in rural areas,we divide historical evolution of rural public cultural services in China into three periods:(i) The period from the founding of New China to the period before " Cultural Revolution" ;(ii) The period from " Cultural Revolution" to the period before the reform and opening-up;(iii) The period after the reform and opening-up.We analyze the defects in the supply of rural public cultural services in China:(i) Difference in the supply of public cultural services between urban and rural areas,caused by urban-rural " dual" structure;(ii) Insufficient supply of rural public cultural services,arising from unclear property rights and executive power of government at all levels;(iii) Structural imbalance in the supply of rural public cultural services,caused by top-down supply decision making mechanism;(iv) Single financing channels of rural public cultural services.From input,decision making,demand expression,financing and endogenous mechanism of supply of rural public cultural services,we put forward the recommendations for improving the supply of public cultural services in China.

Psychological Support for Public-Funded Normal Students Engaged in Teaching Profession

Among primary and secondary school teachers in China, 70% of teachers believe facing more significant occupationalpressure. 63.8% of teachers clearly stated that occupational stress had caused a tremendous impact on them.And this has had adverse effects on them, such as mental, physical, and personal development. This paper studiesthe group of public-funded regular students from the perspective of psychological support. This paper uses theSCL-90 form to investigate the professional psychology of teachers for the psychological support of public-fundedregular students engaged in the teaching profession. And it conducts a survey on the curriculum setting and satisfactionof the public-funded regular students during their study stage. The experimental results of this paper showthat only 11.9% of public-funded regular students are very willing to take root and serve township education.Moreover, the psychological pressure of teachers at different educational stages is quite different.

Probe into the “Mania for School District Houses”——Research into the Motivations for Purchasing School District Houses from the Perspective of Cultural Capital

In recent years,the"mania for school district houses"has disrupted the housing market and undermined education equity and class mobility,thus becoming a common concern.Most existing research focus on market motivations for purchasing school district houses while neglecting the connections between school district houses and cultural and social elements in the process of class reproduction.To make up for this deficiency this article introduces the neighborhood-based cultural capital theory to explore the diversified motivations,the processes of motivation formation,and the determining factors in purchasing school district houses.Reviews and analysis of interview materials revealed that while theories based on western experience can explain the basic purchasing motivations and their formation processes,there are distinct and varied purchasing motivations in China,more comprehensive and complex forms of capital exchange,and more dynamic factors that impact purchases of school district houses.Suggestions on solving the"mania for school district houses"are also presented.

Public Agenda, Media Agenda and Policy Communication Process of Government Annual Reports:Based on the Survey in 19 Chinese Cities

Promoting direct policy communication between policy makers and the public is both an important function of government annual reports (GARs) and a key issue in democratic politics.According to this survey,conducted in 19 major cities in China,to promote the policy communication function of the GARs the government should make full use of changes in public policy communication habits and the convergence of public policy preferences in different groups while dealing with routine problems such as “public opinion deficits” and “being popular among the institutional staff but unnoticed the non-institutional staff.”
