The Coupling And Coordination Research On Land Ecological Security And Economic Development In Susong

Land is the fundamental of everything,providing basic places and material supply for human production and life.Susong relies on better location advantages and abundant natural resources in recent years,the economic growth rate is good,but also inevitably increased the burden of natural ecology.In this context,it is particularly important to study the coordination of land ecological security and economic development,and the premise is to realize the quantitative evaluation of the ecological security situation of land and the level of economic development in Susong.Therefore,the construction of 21 indicators of the three sub-systems of nature-economy-society,the evaluation index system of land ecological security in Susong and the evaluation index system of the economic development of Susong,which consists of 12 indicators of the two subsystems of economic development level and people’s living standard,are constructed,and the index empowerment is carried out by the entropy method.The comprehensive index method was selected to evaluate and analyze the land ecological security and economic development of Susong in 2010-2017,and the coordinated development level of land ecological security and economic development in Susong in 2010-2017 was completed according to the coordination and coordination degree model,and some suggestions were put forward for targeted countermeasures.The conclusions of this paper are as follows:(1)The comprehensive index of land ecological security in Susong 2010-2017 was0.4280,0.3948,0.4917,0.4705,0.5306,0.5945,0.6218,0.7072;However,the ecological security value of natural and safe land in Susong and the increase of land social ecological security value are not as high as the ecological security value of land economy,which shows that the social and economic development is the main driving force for the improvement of the overall land ecological security in Susong.The level sits at risk level,bad level,risk level,risk level,risk level,risk level,better level and sensitivity level respectively;(2)Susong 2010-2017 economic development composite index: 0.0339,0.1090,0.2460,0.3309,0.5697,0.7264,0.8429,1.0000;The index of people’s living standards grew faster and then slowly.The overall level of economic development continued to rise,accelerating growth at the demarcation point in 2013.(3)The coupling coordination of land ecological safety and economic development in Susong 2010-2017 is: 0.1309,0.3404,0.54,0.6138,0.7408,0.8046,0.8363,0.8967,The relationship between the two systems formed the transition from economic lag to ecological lag type in 2014,and the coordination level was highly disordered,moderately disordered,weak coordination,low coordination,moderate coordination,high coordination,high coordination,high coordination,high coordination,and overall towards higher coordination.(4)Countermeasures to promote the coordinated development of land ecological security and county economy in Susong: tap the potential of land resources and realize intensive utilization of conservation;...
