Improved ecological development model for lower Yellow River floodplain,China

In this study,a model for the development of the wide floodplain in the lower Yellow River Basin,in China was developed.This model includes flood control schemes using grading criteria,enables sediment deposition in partitioned zones,and allows free exchange between channel runoff and sediment.The wide floodplain located between the main channel and levees is divided into three typical regions:the tender,low,and high floodplains.Different ecological models should be applied when these floodplains are constructed.This paper describes the associated research ideas and methodology,and clarifies several key issues,including sediment prediction and regulation,land planning,land use,and a multi-dimensional framework of safeguard measures for industries on the lower Yellow River floodplain.A refined ecological development model is proposed for the lower Yellow River floodplain,and future work on ecological and sustainable development of the lower floodplain is suggested.To establish a comprehensive system integrating runoff and sediment resource regulation in the Yellow River Basin,future work should focus on runoff and sediment exchange mechanisms in the wandering lower reaches.Furthermore,it is necessary to improve theories on floodplain planning and ecological construction,and these theories should be integrated with the research findings on land development across the lower Yellow River floodplain.©2020 Hohai University.Production and hosting by Elsevier B.V.This is an open access article under the CC BY-NC-ND license(http://creativecommons.org/licenses/by-nc-nd/4.0/).

Evaluation and welfare effect of coordinated ecological development of the Beijing-Tianjin-Hebei region

Regional coordinated ecological development is a new form of regional coordinated development that aims to construct an ecological civilization in the“new normal”period.The coordinated ecological development of the Beijing-Tianjin-Hebei(BTH)region is especially significant because this region is leading the overall coordinated development and reform in China.Based on complex system theory,synergetics,and the ecological civilization and green development ideas of the“new normal”period,we constructed a regional ecological synergy measurement model that scientifically evaluates the dynamic evolution of the BTH ecological synergy level from 2006 to 2018.Using an econometric model,we also analyzed the welfare effect and the regional heterogeneity of ecological synergy in regional development.First,it was found that in general,the degree of ecological synergy in BTH increased yearly up to 2018 with a strong development trend.The speed of ecological synergy in the Tianjin-Hebei and Beijing-Hebei subsystems was accelerating during that period,but the development potential of the ecological synergy in Beijing-Tianjin was insufficient and slow-growing.Second,whereas Beijing had entered the stage of moderate coordinated ecological development,Tianjin and Hebei remained in the low level of coordinated development;moreover,the coordinated development was unstable.The uneven development of the internal subsystems in BTH restricted the development of the cooperative effect and the overall development of the region.Third,improving the degree of ecological synergy significantly benefited the social and economic welfare in BTH.Finally,the welfare effect of the degree of ecological synergy showed a significant regional heterogeneity,being significantly higher in Tianjin and Hebei than in Beijing.This result indicates that improving the ecological synergy can narrow the development gaps between Tianjin,Hebei,and Beijing.To further improve the level of regional ecological synergy,we should innovate the coordinated model of regional development,implement the collaborative ecological development model,generate new growth drivers for the green development of BTH based on a reasonable division of labor,difference positioning,and active integration,create a soft environment for an innovation ecosystem that promotes regional ecological synergy,and build a regional innovation ecosystem led by Beijing and Xiongan.Next,we should establish a balanced regional-interest mechanism with ecological environmental protection that supports regional green and high-quality development.

Orientation and community participation of ecological development: a case study of Hutuo River in Shijiazhuang City,China

Entrusted to by Shijiazhuang municipal Party committee and government, Shanghai Tongji University fin- ished “The General Planning of Ecological Development Project of Hutuo River in Shijiazhuang City”. It aims to build Hutuo River into a wind-breaking and sand-fixing barrier and ecological protect district in the north of Shijiazhuang based on the recovery of natural ecology to improve the environment of Shijiazhuang city. It also intends to develop the district lightly and build it into a nature beauty spot and big park. After the construction for several years, the general environment of this district has been greatly improved. But during the development, the man-made landscapes are highlighted excessively, which deviates from the construction of nature landscape. The currency of constructing big leisure park gradually comes into being, so the recovery of nature ecological is slow. So, this paper intends to make the orientation to ecological development of Hutuo River in Shijiazhuang city and puts forward the community participation to promote the future development of ecotourism in Shijiazhuang.

Exploring the Goal Synergy between the Ecological Carrying Capacity of Miyun District and the Development of the Ecological Home-stay Industry in Beijing

Green construction in culture and environmental protection will be the development trend in a long run,the urban and suburban area will be ecologically developed as well.Rural revitalization must adhere to the position of historical progress theory and modern concepts,innovate spatial layout,optimize ecological resources,and appropriately determine its historical significance and sustainable development responsibility with reasonable value orientation and environmental ecological carrying capacity for local ecological construction.In order to achieve this responsibility,the authors must expand the dimensions to consider more relevant factors.The guarantee of ecological carrying capacity is an important means to ensure the promotion of ecological civilization.This paper aims to integrate and regulate the goal synergy of the cultural development of the home-stay industry in Miyun District of Beijing by means of the innovative model of sustainable economic development of cultural ecology,ecological people,ecological health preservation and rich home-stay ecological elements.Assuming that the role of the former in promoting the latter can be expanded,then in the range of ecological and cultural towns(conceptual model)that maintain a certain tolerance of ecological carrying capacity,as a characteristic home-stay industry in Miyun,there will be some effective growth,so the integration and development of multiple cultural genes and elements must be the ecological and cultural town model under the enhanced multi-factor aggregation effect,(See the ecological environment carrying capacity development goal A:A=B12345+C1234567 later).This article will explain that the development goals of Miyun's ecological culture and the ecological homestay industry are coordinated,and the two are mutually raised in the same direction.

An Investigation Into Career Development Contexts of University Russian Language Teachers in China(1949-2019)From the Perspective of Ecological Theory

Although much research has been conducted on the interactions between the career development of foreign language teachers and their contexts around the world,a literature review reveals that there exists scanty research on the relationship between university Russian language teachers’career development and their contexts in China since 1949.Based on relevant studies on the career development of foreign language teachers and the ecological theory,this paper involves research on the impact that different ecological systems(micro-,meso-,macro-and exo-ones)have played in the career development of Russian language teachers in China.Participants are 10 Chinese Russian teachers of different ages from different universities in different parts of China.Via literature review,narration methods and semi-structured(in-depth)interviews with the help of NVivo,this research finds that Russian language teachers’career development results from multi-faceted interactions of the following contexts:ideology,Russian language educational policies and personal factors as well as college contexts.This paper concludes with some suggestions for improving Russian language teachers’career development in China.

The Change of Ecological Footprint and Its Effect on Sustainable Development in Beijing of China

Speeding up the environmental protection and construction is one of the major issues in ＂Greener Olympic Games＂ held in Beijing in 2008. Making a thorough study to find out the reliable measures to ecological resumption in Beijing has an important scientific and practical significance. It can provide scientific basis for making a better decision for ＂Greener Olympic Games＂ held in capital Beijing and development in harmony for society and economy, as well as management for ecological environment. By studying of change of ecological footprint from 1990 to 2003 in Beijing, the paper shows that ecological footprint per capita has a strong relativity with population and GDP, and both of the correlation coefficient between them is about 0.92, as well as the fossil energy land has a position in the lead in ecological footprint items. The study also shows that the ecological capacity per capita in Beijing occupied about 1.25% in global ecological capacity per capita. Began 1990, the ecological deficit in Beijing was about 0.72 hm2, which is at strong unsustainable development at present. Finally, the paper suggests social and economic structure should be adjusted as soon as possible, resources should be strengthen sustainable used and population increasing should be controlled strictly, as well as arable land also should be under control used for built-up areas. Simultaneity, the utilizing ratio of energy sources should be increased, and the consumption of energy sources and ecological deficit in Beijing should be reduced in order to speed up the society and economy development in harmony and sustainment.

A climatic environmental performance assessment method for ecological city construction:Application to Beijing Yanqi Lake

In contrast to the input perspective for evaluating planning metrics, this research takes the climatic environmental output effects as the starting point for assessing ecological city construction. Based on approaches such as observation data analysis, meteorological model simulation, and remote sensing, a set of climatic environmental performance assessment methods is developed and established. These methods mainly focus on surface ventilation assessment and urban thermal environment assessment. With the Yanqi Lake ecological development demonstration area located in Huairou district, Beijing as an example, the assessment of the local climatic environment before and after the construction are conducted, and relevant policy suggestions for urban planning and construction are presented. The results show that after development, the ventilation capacity will decrease overall and the ventilation potential index will decrease from 0.53 to 0.44. While this is not a large reduction, and is still at a favorable level, the ventilation potential in some local areas will markedly decrease. Furthermore, the thermal environment will become poorer to some extent; the urban heat island(UHI) area and intensity will increase compared with the current situation;continuous heat islands may occur in local areas; the UHI potential index of the core area will rise from 0.0878 to 0.1217(still a favorable level).Therefore, urban surfaces should be carefully developed and arranged during planning. It is suggested that the negative impacts of large areas of urban construction on the local climatic environment in the Yanqi Lake could be mitigated by 1) strengthening the airflow by introducing fresh,cold, northwesterly air via constructed ventilation corridors, 2) increasing the number of ecological cold sources, particularly for water bodies and green belts to prevent the UHI in the southern region of Yanqi Lake from becoming linked with each other, and 3) considering a pre-program before sub-domain and building planning to obtain optimum building locations. Different construction standards should be developed for different ventilation potential and UHI intensity levels. For strong heat island areas, land areas should be reserved to serve as cold sources.

Evaluation of Ecological Sustainability Based on Ecological Footprint in Hunan Province

To make clear ecological sustainable development in Hunan Province, biomass resources and the energy consumption indexes of Hunan Province in 2013 were selected, and quantity analysis of the regional ecological consumption and the ecological carrying capacity was carried out using the ecological footprint method. The results showed that the net ecological deficit per capita was 1.718 hm2 in 2013 in Hunan Province, which indicated the regional development was beyond the scope of ecological carrying capacity. So, according to the present unsustainable situation, the corresponding development suggestions were put forward.

Integrating Sustainable Development into Global Institutions:Reforming the United Nations

This article will briefly outline the origins,structure and functions of United Nations Environment Program and the Commission on Sustainable Development in the context of the goals of ecologically sustainable development(ESD).Economic development,social development and environmental protection form the three interconnected parts of ESD.The achievements of the key UN environmental institutions and programs in opening up the global system to civil society,the private sector and a diversity of actors and interests,promoting the role of poverty alleviation as part of ESD through the Millennium Development Goals,and facilitating important Multilateral Environmental Agreements should be recognized.However,with these notable exceptions,organizations such as United Nations Environment Program and the Commission on Sustainable Development have become weak in scientific and technical leadership,global policy,co-ordination(inside and outside the UN) and has few achievements in the international and national implementation of obligations and standards in Global Environmental Governance-including enforcement,compliance and effectiveness.This article will outline the key reasons for this inadequacy.Attention will also be focused on the way forward through of a new United Nations Environment Organization.This will require a clarification of purpose and function(within the UN system and as part of global governance structures) as well as consideration of whether it depends on system-wide UN reform.It is recommended that medium and long term strategies for reform are necessary.

Rural Domestic Sewage Treatment Model: Case Study Based on Dongying Section of the Yellow River Basin

The 20th National Congress of the Communist Party of China proposed to promote the improvement of urban and rural living environment and build livable and workable villages and beautiful villages. The development and challenges of rural domestic sewage treatment coexist. Based on the field investigation of 15 administrative villages in 3 districts and counties of Dongying City, there is a big gap between the development status of rural domestic sewage treatment and expectations. Investigate rural domestic sewage treatment cases in-depth, and condense four modes of primitive, developmental, mature and advanced in a variety of different rural domestic sewage treatment models for discussion, among which, the village sewage treatment work under the mature mode has achieved remarkable results, and is at the forefront of the current rural domestic sewage treatment. Through the multi-case analysis method, the practical dilemma of sewage treatment in different models of villages is summarized, and the feasible improvement path is explored, which contributes to the ecological protection and high-quality development of Dongying and the Yellow River Basin.

Green Barriers： Obstacle or Stimulation ？

Most viewpoints in China consider green barrier is one kind of non-tariff barriers imposed by developed countries and is unfair to developing countries. Different from these, this paper points out that green barriers, evolving from the background of sustainable development theory and the principle of environment protection, have positive effect on ideology, international institutional arrangement and innovation stimulation. Demonstrating the rationality of green barriers, the paper puts forward that green barriers should be regarded as the stimulation for technology innovation and industrial restructure rather than obstacles. The best way to surmount the green barriers for Chinese government and enterprises is to implement circular economy and clean production so as to achieve the harmony of trade, environment and economic development.
