Evaluation And Research On Sustainable Development Of Land Ecology In Shanxi Province

Shanxi Province is famous for its energy and industrial development,and is listed as a key experimental city by our country in the exploration of changing and developing original economic mode that relies on resource consumption.However,due to energy exploitation and urbanization development,the balance of land ecosystem in Shanxi Province has been damaged in recent years,and the sustainability,safety and health of land ecology have been severely affected.The overall ecological environment is worrying.In recent years,The exploration of the harmonious relationship between human and nature by our country and the party has experienced a high degree of improvement from the level of recognition to the level of requirements and deployment and in the September 11,2017,our country put forward special rectification opinions on the development of Shanxi Province,which point that Shanxi should mainly focuses on the ecological priority principle,should deepen the construction of ecological civilization,strengthen protection and restoration of ecological resources development area,which inspire us to think deeply about the problems of land ecological security and sustainable development.This paper studies and analyzes land ecological footprint,the coupling coordination degree of land ecological security and urbanization development in Shanxi Province and its 11 cities from year of 2005 to 2018.Finally,TOPSIS multi-criteria decision model is applied to integrate these two indicators into the programming system,and the comprehensive evaluation score of each city is obtained.The studies of ecological footprint start from building of biological resources account and fossil-energy resources account,and then the paper calculates the equilibrium factor and yield factor through the heat value,then calculates ecological footprint cooperating with all kinds of product categories,such as agricultural products,forest products,aquatic products,livestock products and fossil energy products.Finally the psper calculates ecological footprint respectively of each city and the whole province,from year of 2005 to 2018.In the final analysis,the paper calculate the ecological deficits and surpluses,land natural capital flow rate of return and stock-flow utilization ratio,ecological footprint per ten thousands GDP and ecological footprint depth and breadth.On the other hand,the studies of coupling coordination degree is beginning with establishment of land ecological security evaluation index system and urbanization development evaluation index system,then it calculates comprehensive weight by using factor-analysis method and entropy method,then coupling coordination index ‘s temporal and spatial changes in Shanxi Province and its cities from year of 2005 to 2018 are concluded.The paper finally analyzes the global spatial autocorrelation and local spatial autocorrelation to clear the properties of each city's spatial agglomeration and heterogeneity.Finally,in order to solve the conflict between the two evaluation results and reduce the decision-making risks,the paper incorporates the two indexes into the TOPSIS multi-criteria decision-making model through programming,and obtains the comprehensive score of land ecological sustainable development evaluation for each city.Paper's main purpose is to take a comprehensive analysis on the status of ecological footprint of Shanxi Province and coupling coordination through the TOPSIS multi-criteria decision-making model,and to make a precise focus on the ecological short board of Shanxi Province and its cities,on the contradiction between man and land and sustainable development in the process of Urbanization,and to provide basis for the implementation of the rational development and utilization of resources,protection and restoration of ecological environment construction in Shanxi Province in the future.And to show the urgency of optimizing economic structure adjustment and transformation of economic development patterns in Shanxi.All in all,to better coordinate with regional resources,make the province and its cities' economy,society,ecology and humanity move towards sustainable development direction.
