Strategies for Prioritizing Ecological Construction with Consideration of Agricultural Industry Development in Northern China’s Agro- pastoral Ecotone : A Perspective of Opportunity Cost

In northern China’s agro-pastoral ecotone,there are conflicts between agricultural industry and ecological construction resource competition,and also problems urgently to be solved for economic growth and sustainable ecological improvement.Taking the development concept of"lucid waters and lush mountains being mountains of gold and silver"as the guiding principle of prioritizing ecological and green development,this paper studied the strategies for prioritizing ecological construction with consideration of economic development of agricultural industry from the perspective of opportunity cost.Through the analysis of opportunity cost,externality,and Pareto optimal theory,and using the calculation method of the unit equivalent factor value of terrestrial ecological service function,this paper calculated the ecological service value of forest,grassland,and farmland.It found that the ecological value of forest and grassland per unit area was greater than the ecological value of agricultural industry.This indicates that the opportunity cost of farmland for ecological construction was less than that of agricultural industry.Based on the theoretical and quantitative analysis,it came up with recommendations for establishing a comprehensive system for prioritizing ecological construction with consideration of agricultural industry development and establishing and improving the incentive mechanism of ecological construction.

On ecological inheritance construction of intangible cultural heritage in era of intellectual media

It is known that intangible cultural heritage is an important resource of the cultural soft power in a country, and it is also an organic component and representation of national history, spirit and cohesion.Therefore, a good inheritance of intangible cultural heritage is of great significance for carrying forward the ethical basis of human culture as well as maintaining its value core. Nowadays, the rapid intelligentization of media has ushered in the era of intellectual media, with characteristics of “massive media, man-machine integration and self-evolution”. In the era of intellectual media, traces of intelligent technologies can be seen everywhere, and the ecology of the inheritance of intangible cultural heritage has been reconstructed. Under this circumstance, the author firstly makes clarification of the advancement of the era, which has given a new logic of intangible cultural heritage inheritance, and various intelligent powers should be developed including intelligent acquisition, processing and judgement ability of content value. Then, the technology empowerment is analyzed, which has made reconstruction of intangible cultural heritage inheritance: while being digitalized,the inheritance of intangible cultural heritage has become systematized in way of “Points, Lines and Planes” at the same time. Therefore, the communication ecology of intangible cultural heritage could be established as a new approach of inheritance via all sorts of intelligent technologies, so as to promote Chinese cultural soft power and enhance our national image in the long run.

How does the construction of China’s ecological civilization affect the health burden of urban and rural residents?

Accelerating the construction of ecological civilization and promoting the management of health environment problems is one of the core elements of the implementation of the“Beautiful China”and“Healthy China”strategies with Chinese characteristics in the new era.Based on the scientific connotation of ecological civilization,this paper systematically assesses the level of interprovincial ecological civilization construction in China using the combined CRITIC empowerment method and explores the impact of ecological civilization construction on the health burden of urban and rural residents using interprovincial panel data from 2003 to 2018 with the help of panel feasible generalized least squares,simultaneous equation estimation,and the extended regression model.It is found that there is a significant inverted U-shaped relationship between provincial ecological civilization construction and urban and rural residents’economic health burden,as well as a significant U-shaped relationship between ecological civilization construction and urban and rural residents’disease burden.Fiscal decentralization,urbanization,and industrialization are the three important indirect mechanisms through which ecological civilization affects the health burden of urban and rural residents,and fiscal decentralization plays a typical role in crowding out the health effect of ecological civilization.In the eastern and central regions,ecological civilization construction has effectively reduced the health burden of urban and rural residents,but it is more significant for improving the economic health burden of rural residents.While the“catching-up trend”of the progress of ecological civilization construction in the western region is obvious,ecological civilization plays an important role in alleviating the economic health burden of urban residents.After the robustness test,the conclusion still holds.This study provides an important empirical basis for local governments to improve the accuracy of their policies in promoting the“Beautiful China”and“Healthy China”strategies.

An analysis on ecological civilization construction in Gansu based on a quantified SWOT framework

Ecological civilization （EC） construction has become one of the key elements of China＇s reform and development process, since it was put forward at the 17th National People＇s Congress （NPC） in 2007 and improved at the 18th NPC in 2012, and stressed at the third plenary session of the 18th NPC. The provincial areas are the most important pilot units of EC strategy. Therefore, research on EC at the provincial level can meet the practical demand for EC in China. Based on the existing provincial circumstances in Gansu and its significant position as an ecological barrier in northwestern China, and aiming at the core issue of why and how to build EC in Gansu, this paper employs SWOT （strengths, weaknesses, opportunities, threats） analysis, the Delphi method, and a combined quantitative analysis and coordinate method, and then calculates the relevant strategic orientation angle （0 = 1.4605） and strength coefficient （p = 0.53）. The results show that Gansu should take an opportunities-dominated strategy, and choose opportunity-strength measures, so the province can increase its in- ternal strengths and decrease its weaknesses with external promote an EC construction strategy. opportunities. Specific measures are recommended to actively

Spatial Pattern and Influencing Factors of Regional Ecological Civilisation Construction in China

Ecological civilisation construction is a strategy for regional sustainable development based on a regional system of human-land relations. The comprehensive measurement and regional differentiation in construction levels are the key issues of ecological civilisation construction. This study aims to build 35 index systems that coalesce on four aspects: ecological economic adjustment and operation, ecological and social development and progress, ecological resources and environmental security, and ecological institutional and cultural awareness. We measured and evaluated the level of ecological civilisation construction of 329 cities(prefecture-level cities, autonomous prefectures and leagues) in 2018 using a comprehensive evaluation system and a spatial autocorrelation method to assess spatial differences in the level of ecological civilisation construction across China. This approach takes ‘the humanities-economic geography’ comprehensive perspective and uses a GWR(geographically weighted regression) model to analyse 10 influencing factors. Results show that: 1) the level of ecological construction can be divided into five types: higher, high, medium, low, and lower levels, according to the evaluation score. The five types are spindle-shaped in quantity and there is a significant imbalance in their spatial distribution, mainly trending from the southeast coast to the northwest. The land is decreasing, and the southern region is higher in level than the northern region. 2) The results of the spatial autocorrelation method show obvious spatial differences in ecological civilisation construction across China and that the level of ecological civilisation construction is positively autocorrelated. From east to west, the hot zone gradually transitions to a cold zone. A high-high type is mainly distributed in eastern coastal cities of China, and the number of high-low and low-high types are small. The low-low type is mainly distributed in the northwestern and northeastern regions. 3) The effect of influencing factors is heterogeneous in their spatial distribution, and the abundance of ecological resources is the most influential factor. According to the main influencing factors, each region should adhere to the principle of differentiation according to local conditions when choosing its ecological civilisation construction path and establishing an assessment mechanism. This study provides a scientific basis for enriching the regional level measurement of ecological civilisation construction, clarifying the current level of ecological civilisation construction in China, and implementing the regional differentiation path of ecological civilisation construction.

Landscape planning and ecology construction of wetland comprehensive protected area system in the Sanjiang Plain

Wetland is one of the richest biodiversity areas in the earth. The main purpose of establishing wetland protected area is to protect biodiversity, and the protection of ecosystem diversity and landscape diversity is the key to protect biodiversity. In order to protect regional ecosystem and landscape, it is a good way to establish wetland comprehensive protected area which connected wetland nature reserves by habitat corridors. The Sanjiang Plain as a study area, its landscape evaluation index system on wetland protected area was studied, and some problems on landscape planning and ecology construction were further approached in this paper.It showed that establishing wetland comprehensive protected area is very important to protect regional wetlands, to maintain ecological balance, and to improve the sustainable development of agriculture and industry in this region.

Quantifying impacts of climate and human activities on the grassland in the Three-River Headwater Region after two phases of Ecological Project

The Three-River Headwater Region(TRHR)of China is a typical representative of the alpine environment in the Central Asian plateau and the alpine grassland in the world.Grassland degradation is one of its serious eco-logical problems.The purpose of this study is to quantify the joint impacts of climate and human activities on grassland changes in TRHR after two phases of Ecological Conservation and Construction Project(Ecological Project).Grassland vegetation coverage is selected as an indicator for analyzing grassland changes.We adopt Sen+Mann-Kendall trend analysis,residual trend analysis and correlation analysis methods to analyze the trends in spatial-temporal changes and driving factors of grassland in TRHR from 2000 to 2019.The results show that:(1)The grassland has been mainly restored,and the degraded grassland area only accounts for 1.66%of TRHR.After the implementation of the first phase of the Ecological Project,the percentage of restored grassland area has significantly increased from 8.82%to 24.57%,and slightly decreased during the second phase.(2)The establish-ment of national nature reserves and the implementation of the Ecological Project have changed the situation that“the grassland inside the reserve is worse than that outside the reserve”.(3)Grassland restoration is mainly af-fected by the joint effects of climate and human activities.Nevertheless,grassland degradation is mainly affected by human activities such as overgrazing and grassland reclamation.All of these findings can enrich our under-standing of grassland restoration in TRHR.Artificial measures have certain limitations in promoting grassland restoration.Natural restoration should be considered when human beings strengthen ecological conservation and transform their production and life styles.

Research on the Realization Mechanism of and Approach to Ecological Product Valuations

Ecological product is an innovative practice for ecological valuations in China. Due to the influence of historical conditions and development stages in China, research on the realization of ecological valuations has lagged. In the new era, the construction of an ecological civilization guided by the "Two Mountains" theory has been promoted to the national strategic level and is supporting the growth of theoretical research and practical exploration based on the understanding of ecological product values. We want to innovate and improve the system used to realize the value of ecological products by applying the existing research, which focuses on the concept definition of ecological products and their correlation theories. Through systematic expansion and upgrades in this system, the evaluation accuracy of ecological products can be improved, providing valuable references for further practical exploration and promoting an ecological culture in China.

Forestry development to reduce poverty and improve the environment

Poverty reduction is a world-wide concern.At the end of 2017,according to the rural poverty standard in China,there were 30.46 million poor in China.However,complete poverty alleviation by the end of 2020 had been achieved.This is significant and complicated,especially as poverty-stricken areas and ecologically fragile areas overlap.During the process of poverty alleviation,the development of forestry projects was not only conducive to improving the environment but also an important way to reduce poverty.Therefore,based on an analysis of the causes of poverty-stricken areas,this study examined successful cases in different regions and proposed ways to promote economic growth:providing state subsidies for tree planting and forest maintenance;developing undergrowth economy;and/or initiating an industrial chain.It also introduces principles to promote forestry progress,according to local conditions,keeping a balance between economic development and the environment.This study provides effective ways to promote forestry development and rural poverty alleviation.

A profile of environmental science in China

This paper concisely introduced the eco-environmental survey in China and the Chinese scientific programme for environmental research which is being practiced or being planned. China has established a nation-wide system relating to environmental scientific research and environmental administration and has taken the following strategies for solving the environment problems: (1) a series of laws and regulations for environmental protection has been promulgated so as to strengthen the legal administration and economic punishment. (2) the idea of ecological construction has been proposed for the purpose of taking the environmental protection work into the consideration of the national and provincial (or regional) economic construction planning. (3) spreading ecological engineering and ecological technologies have reduced the pollutant sources and have increased the industrial and agricultural economic profit.

Countermeasures for Scientific Utilization of Forest Resources in China

Ecological environment in China refers to the state of people’s living environment,which is mainly represented in soil erosion,garbage pollution,air pollution,noise pollution and so on.The basic situation of ecological environment in China is that the governance capacity is far behind the speed of destruction,and the ecological deficit is gradually expanding.Excessive deforestation,indiscriminate reclamation,exceeding hunting,and random wild plants picking have been failed to be prohibited.Forest fires and pests and diseases are still very serious threats to forestry.In this paper,based on the generality of sustainable development,a systematic discussion was made to the framework theory of sustainable forestry development and sustainable forest management,followed by further exploration of forest resources and sustainable development.Moreover,based on the investigation on related concepts of forest resources,review of historic process of forest resources,and analysis on the grim situation of forest resources,some countermeasures were proposed to carry out the sustainable utilization of forest resources in China.

Impact of the Construction of Ecological Civilization Demonstration Areas on Carbon Emission Intensity

The development path from attaching importance to environmental protection to the theory of ecological conservation,then to piloting ecological civilization demonstration areas,marks that China’s ecological conservation has gradually moved from theoretical construction to practical exploration,based on the new idea that“lucid waters and lush mountains are invaluable assets.”It is still an ordeal for China’s ecological conservation in the context of global warming how to reduce carbon emission intensity while maintaining sustained economic growth.Under the dual constraints of peaking carbon dioxide emissions before 2030 and achieving carbon neutrality before 2060(“dual carbon”goals),this paper employs the five national ecological civilization pilot demonstration areas(ECDAs)established in 2014 as quasi-natural experiments based on the panel data of 30 Chinese provincial regions from 2003 to 2019.Based on the analysis of the policy implementation background and the theoretical mechanism of its impact on carbon emission intensity,the synthetic control method and difference in differences method are adopted to test the impact of the construction of ECDAs on carbon emission intensity and examine the spatial spillover effect of the pilot policies.The study shows that the construction of ECDAs has significantly reduced carbon emission intensity as a whole,especially in Fujian,Guizhou,and Yunnan Provinces.Moreover,the conclusions successfully pass the robustness test.The mechanism analysis results demonstrate that the construction of ECDAs can lower carbon emission intensity through the positive incentives from boosting technological progress and developing green finance,and the reversal pressure mechanism of optimizing the energy structure and improving the market segmentation.The analysis results of the spatial spillover effect indicate that the construction of ECDAs plays a significant role in reducing carbon emission intensity in the region and its adjacent areas.Therefore,China should introduce ECDAs and the experience gained to more regions.Meanwhile,China should spare no effort to seek multi-dimensional paths to reduce carbon emissions in view of regional differences in green development,and strengthen cross-regional communications and cooperation to realize the goals of carbon emission reduction.

Ecological conservation, remediation and construction for building an ecological civilization in China: concepts for ecological activity

This paper explains and discusses the concepts of ecological conservation and construction in China in three parts. The first part provides a brief description of the historical background of ecological activities in China and their major achievements in the past. The second part is a comprehensive review of various types of ecological control activity aimed at the improvement of natural and artificially established ecosystems at the landscape,regional(watershed) and higher levels. The scope of and differences between some ecological terms used in China such as ecological protection, conservation, remediation(rehabilitation), restoration as well as the reestablishment of new ecosystems are elaborated. The review suggests that the term "ecological conservation and construction"should be used to embrace all types of ecological control activity in China. Finally, five guidelines are proposed for promoting the implementation of ecological conservation and construction in China based on the two important governmental documents related to the development of ecological civilization in China.
