THE ROLLING DEVELOPMENT MODEL OF ECOLOGICAL ECONOMY COMBINED WATER CONSERVANCY CONSTRUCTION WITH SCHISTOSOMIASIS CONTROL

On the basis of classification of geographical properties a rolling develop-ment goal programming model is formulated in correspondence with the ecopatterngroup in Four-Lake Area. In this model, the control of schistosomiasis and strengthen-ing of the drainage-storage function are both regarded as ecological measures duringthe process of multi-year(r_0) ecological economic rolling development to make theecoagricultural system in this area ioto a stably operating, ordered, and good cyclicsystem under the support of some controllable factors.

Research on Coupling Relationship between Social Economy and Ecological Environment in Jinghe County of Aiby Lake Basin,Xinjiang

Based on the theory of sustainable development,using the theory and method of coupling relationship,the main city of Aiby Lake basin——Jinghe County in Xinjiang is selected. Based on the analyses of natural condition,population growth,land use type and ecological environment,the comprehensive evaluation index systems of socio-economic development level and eco-environment quality in Jinghe County are constructed. Using principal component analysis,a comprehensive evaluation of socio-economic development level and ecological environment quality in Jinghe County is conducted by combining with Excel. Their coupling relationship is studied,and quantitative coordination degree between social economy and ecological environment in Jinghe County is obtained. The results show that in recent 50 years,socio-economic development level in Jinghe County is rising,but the ecological environment quality is falling. Their coupling degree C changes during [- 1. 260, ＋ 0. 482],in other words,their coupling relationship is changing between ＂ reluctant coordination＂ and ＂ not coordination＂. After entering into the 21 stcentury,their coupling relationship is basically ＂ reluctant coordination＂. On this basis,the existing problems in the process of sustainable development in Jinghe County are analyzed,and the suggestions about promoting coordinated development between social economy and ecological environment are put forward.

The bibliometrics survey of ecological economic research:A knowledge mapping analysis based on the SCI and SSCI database

Based on bibliometrics and knowledge mapping analysis method,this paper uses CiteSpace,a visual literature analysis tool,to analyze 3794 related documents with the theme of“economic economy”in SCI and SSCI databases from 2010 to 2020,including authors,institutions,subject headings and literature co-citation,so as to reveal the development and hot spots of ecological economic research.The results show that in recent years,the number of documents on ecological economic research has been increasing,and developed countries are dominant.China’s research in this field has developed rapidly and has certain advantages in terms of quantity and quality.The institution with the largest number of papers is Chinese Academy Science,followed by Beijing Normal University,University of Chinese Academy of Sciences,Peking University and Universitat autonomy de Barcelona;research hotspots in recent 10 years include“sustainability”,“management”,“climate change”,“impact”,“economy”,“china”,“conservation”,“ecosystem service”,etc.The top three journals are Sustainability,Journal of Cleaner Production,and Ecological Economics,accounting for about 10%of the total number of papers published.The hot spots of ecological economic research in 2010-2020 can be divided into three stages,with different theme words emerging in each stage.From 2018 to 2020,the theme word of high-strength emergence is“anthropocene”,which indicates that“anthropocene”may be the focus of future research.

A Review of Research on Ecological Economics Based on Bibliometrics

The development of ecological economics is a major strategy for development in the 21st century.Although scholars have been rising more and more interesting for ecological economic over the past 10 years,it is still unclear what is the change will be facing in the future.In order to provide a theoretical basis for the future development of ecological economy,our article analyzes the current research progress of ecological economy on the basis of a bibliometric analysis.The results show that(1)sustainable development of an ecological economy is a hot research topic;(2)there is little cooperation and exchange between institutions and among scholars regarding ecological economics;(3)the number of publications on ecological economics is increasing,with a relatively large number being published in China.Therefore,we must strengthen the cooperation between institutions and among scholars and improve the research content,vision,and methods in this field.This study provides a theoretical basis for the future development of ecological economy.

Research and Application of Sustainable Development of Energy

Based on the analysis and summary of traditional energy ecological footprint （EEF） and its research development at home and abroad, a modified method to measure energy ecological footprint is proposed by combining energy ecological footprint with the area of biological productive forest land from a standpoint of material flow ＂energy consumption - CO2 emissions - woodland absorption＂, and is used to measure the energy ecological footprint and carbon emissions in Tianjin City from 1995 to 2010. The results show that EEF per capita has increased from 1. 739 8 to 3.078 5 ghm2 during 1995 -2010, and has a significant correlation with GDP per capita in annual average growth rate （R~ =0. 877 6, P 〈0.05）. Among the compositions of EEF, the percentage of coal footprint has decreased from 62% to 50%, while the others have increased to some de- gree. Meanwhile, the output value of EEF has increased from 5 687.71 to 23 061.93 yuan/ghm2, and the elastic coefficient of EEF which has in- creased from 0.15 to 0.69 shows approximate cyclical fluctuations. It is indicated that with the adjustment of energy structure in Tianjin in the past 16 years, energy utilization efficiency has been becoming increasingly bigger. However, ecological pressure on the environment is a growing problem in the next few years, so it is urgent to shift energy use patterns and increase energy conservation efforts for Tianjin City.

The Optimization of The Ecological Economic Development for the Upper Reaches of the Yangtze River（Changjiang）

To study the economic development for the upper reaches of the Yangtze River. We seleCt a typital reston-Qingchuan County in Province Sichuan. In this paper. the ecological economic pattern and developing strategy Of Qinschuan county were expounded and proved. ThebaSiC thought and method of research were described. Finally, two kinds of the sptem of modelthat applied in our study successfuly were introduced.
