| As the carrier of human production and life,land is the basis of human survival and development to realize the sustainable utilization of land resources.In recent years,with the development of urbanization and industrialization,human beings abuse land and expand cities in disorder,which causes problems of soil erosion,desertification,salinization and land pollution.These problems seriously affect the sustainable use of land resources.According to the characteristics of land use in Inner Mongolia,we have established a set of index system of sustainable evaluation of land resources in accordance with the research area,adopted the AHP-Entropy combined weight method to determine the index weight,and used the comprehensive evaluation method to calculate the evaluation value of sustainable utilization of land resources in Inner Mongolia.We analyzed the spatial and temporal changes of sustainable land use in 12 League cities in Inner Mongolia from 2009 to 2017,and determined the key factors affecting the sustainable land use in the study area by the key degree model.The results show that:(1)The sustainable utilization level of land resources in 12 union cities of Inner Mongolia was on the rise in 2009-2017 years.The Eastern Inner Mongolia,including Hulunbuir,Xing'an and Tongliao,has a good level of sustainable development of land resources.(2)From the three subsystems of economic feasibility,social acceptability and environmental resource sustainability,we conclude that the sustainable utilization of land resources and the level of economic feasibility in Inner Mongolia are on the rise,and the best level of economic development is located in the Huhhot-Baotou-Erdos economic belt of Inner Mongolia.The overall changes of social acceptability and environmental resources sustainability are not significant,and the League cities in eastern Inner Mongolia are superior to other league cities.(3)Through the analysis of key factors,we obtain that the sustainable use of land resources. |
