Analysis Of The Coupling Relationship Between Land Use And Ecological Environment In Baiyin City

Land is the material basis necessary for human production and life.With the implementation of urban and rural integration construction in China,urban construction land is increasing,and the pressure on land is increasing.Unreasonable land use patterns and serious pollution of land resources have led to a decline in the quality of human settlements and a deteriorating ecological environment,which seriously hindered the economic,ecological and social benefits of land use.This paper selects Baiyin City of Gansu Province as the research area,combines the actual situation of land use and the change of ecological environment in Baiyin City,constructs the evaluation index system,and uses the entropy method and the analytic hierarchy method to determine the weight of each selected index.The value,and the coupling degree model and the coupling development degree model are used to measure the degree of coupling development of land use and ecological environment in Baiyin City from 2005 to 2015,and the types of coupling development are analyzed in detail.The following conclusions are drawn:(1)From 2005 to 2015,the land use level and ecological environment level of Baiyin City showed a synchronous upward trend.The comprehensive evaluation index of land use and the comprehensive index of ecological environment assessment at the end of the evaluation period were 0.3015 and 0.3453,respectively,and the index difference was 0.0438,indicating the ecology of Baiyin City.The environment has not been seriously damaged by the development and utilization of land and economic development.(2)There is a mutual coupling and interaction relationship between land use and ecological environment in Baiyin City.The degree of coupling between 2005 and2015 is high,and the coupling degree index is between 0.98-1.The index of land use and ecological environment coupling development in Baiyin City showed a gradual upward trend from 2005 to 2015,but the index was lower overall,and the index was between 0.43-0.56,indicating that the coupling between land use and ecologicalenvironment in Baiyin City was low.Corresponding measures should be taken to improve.(3)In 2015,the coupling relationship between land use and ecological environment in Baiyin City was characterized by barely coupled land use lag,indicating that land use in Baiyin City is not reasonable.The relationship between land use level and ecological environment has not been coordinated in the past decade..According to the research results,it is recommended to explore the coupling development of land use and ecological environment in Baiyin City: urban construction areas should strengthen ecological environment construction,effectively protect the ecological environment,improve the level of land intensive use and ecological environment protection,transform land use patterns,and promote resources.Reasonable integration and utilization.
