Research On The Coordinated Development Of Economic Development, Land Intensive Use And Ecological Environment Coupling In Shaanxi Province

With the development of economy,the progress of society and the increase of population,the demand for land is increasing,which will inevitably exert great pressure on the ecological environment.Therefore,how to ensure a good ecological environment while developing the economy and how to reduce the pressure on the ecological environment at the same time of urbanization expansion is an important issue that urgently needs to be studied.In this paper,based on the realistic background,to the economic development,the coupling development of land intensive utilization and the ecological environment research,enrich the research content about land intensive utilization,enriched the coupling coordination theory,more perfect for intensive land use evaluation index,and also provide certain reference value to the economic development of shaanxi province,in shaanxi province of grain and cultivated land protection has important significance.Firstly,this paper introduces the coupling development model in physics,and on this basis,draws on the related research of economic development,land intensive utilization and ecological environment evaluation of many scholars to construct the evaluation Index system of economic development,land intensive utilization and ecological environment.Based on the entropy value method,this paper determines the weight of the evaluation index,and on this basis,analyzes the overall development situation of Shaanxi Province from 2008 to 2017,and determines the importance of the evaluation index to the coupling and coordinated development of Shaanxi Province by means of grey correlation analysis.It was found that the 0.834964 factors of total industrial emissions(0.901142),construction land were two or three industrial GDP(0.881443),comprehensive utilization of industrial solid waste(0.854431)and GDP per capita(four)were ranked above.It shows that the most important effect of the coupling system on Shaanxi Province is the pollution of the environment,so Shaanxi province should vigorously strengthen the management of the ecological environment in the future,so as to improve the coupling coordination degree of the system.At the same time,the coupling coordination degree of each city in the past three years was made by Arcgis 10.4.1,and the system coupling changes of cities in Shaanxi province were analyzed by using the study object of 2008 years,2012 and 2016 in Shaanxi Province.It is concluded that except ?'an has always maintained a high level of good coupling coordination,other cities because of inadequate economic development,industrial pollution of the ecological environment is heavier,resulting in a low level of coupling coordination.After analyzing the time series and spatial changes of shaanxi province,the paper puts forward the following Suggestions:vigorously developing economy and maintaining sustainable economic growth;Reduce pollution discharge and intensify pollution control;We will rationally strengthen the intensive use of agricultural land and land for construction.In general,the innovation of this paper is that economic development,intensive land use and ecological environment are concentrated in the same model for research and analysis,and the index factors are ranked by gray correlation analysis method,and it is concluded that the emission of industrial waste gas is the most important factor.
