Evaluation Of Comprehensive Land Bearing Capacity In Feixi County

As the most basic element of social production,land resource is the material carrier of all human activities.With the acceleration of China's urbanization process,the contradiction between land resources and the economy,society and ecological environment is becoming increasingly prominent.How to ease the tense human-land relationship and make rational use of land resources has become an important problem to be solved urgently.This paper constructs and evaluates the evaluation index system of comprehensive bearing capacity of land in Feixi county from four sub-systems of bearing capacity of land resources,economic bearing capacity,social bearing capacity and ecological environment bearing capacity.Major obstacle factors affecting the comprehensive bearing capacity of land in Feixi county from 2010 to 2017 were identified by using factor analysis of obstacle degree.Then the coupling coordination degree evaluation model is used to evaluate the coupling coordination degree among the subsystems of comprehensive land bearing capacity in Feixi county.The research results are as follows:(1)From 2010 to 2017,the overall development trend of the comprehensive land carrying capacity in Feixi County is good.The comprehensive land carrying capacity has undergone a process from a lower level to a higher level.(2)Through the analysis of restrictive factors on the comprehensive land carrying capacity of Feixi county from 2010 to 2017,it can be seen that the per capita construction land area,per capita cultivated land area,per unit yield of grain,the proportion of environmental protection input in GDP and per capita water resources have become the main factors restricting the development of the land carrying capacity of Feixi county in the recent 8 years.(3)The coupling coordination degree of the four subsystems of the comprehensive land carrying capacity in Feixi County from 2010 to 2017 is generally at a low level.In 2016,the system coupling coordination degree reached the best state in eight years,and was on the verge of imbalance.In 2017,the system coupling coordination degree decreased to a slight imbalance level.
