Study On Coupling Relationship Between Land Use And Eco-environment In Hohhot City

Land use and ecological environment are independent of each other and are two open and interactive systems In this complex system of mutual restraint,man is the main body,human production and life play a leading role,which requires people to clearly understand the development and utilization of land in the process of the possible impact,so to adhere to a reasonable and sustainable Development and utilization of the principle,its purpose is to achieve a social and economic benefits and ecological and environmental benefits go hand in hand win-win model.In this context,the correct analysis of land use and ecological environment in Hohhot is of great significance to the economic development of Hohhot.Based on the theory of sustainable development,man-land coordination,eco-economic theory and system engineering theory,this paper regards Hohhot as the research area of this paper,and its research goal is the coupling relationship between land use and ecological environment in Hohhot.Land use and ecological environment,this paper summarizes and draws on the research methods of the coupling relationship between land use and ecological environment,and constructs the evaluation index of the coupling relationship between land use and ecological environment in this paper and the actual situation of the study area.Evaluation model.Based on the data of land use and ecological environment in Hohhot from 2006 to 2015,this paper makes a quantitative and qualitative analysis,and puts forward the corresponding countermeasures and suggestions under the empirical research results.The results of this study show that:(1)The gray relational method is used to obtain the land use structure in the land use system.The degree of land use and the land use benefit are not the same as the ecological environment,and the correlation between the land use structure and the ecological environment is the highest,which is 0.784;The correlation degree between land use efficiency and ecological environment is 0.782,and the correlation between land use benefit and ecological environment is weaker than that of the above.In the same way,the ecological cultivation ability,ecological environment pressure and environmental management level in the ecological environment are not the same as the land use degree,among which the ecological conservation ability is the highest degree of land use and the land use level is 0.788;the level of environmental management and land use The correlation degree is 0.764,and the correlation between the ecological environment pressure and the land use is weaker than the above two,which is 0.706.(2)Gray relational coupling evaluation model The comprehensive coupling degree of land use and ecological environment system in Hohhot from 2006 to 2015 is 0.7528.(3)The entropy weight method is used to weight each index in the land use system and the ecological environment system,and the coupling index of the land use index and the comprehensive index of ecological environment in Hohhot from 2006 to 2015 are obtained respectively.Coupling Degree of Land Use and Eco-environment System in 2006-2015.(4)The land use comprehensive index derived from the coupled model can be seen that the land use in Hohhot is still very good,the index is relatively stable.Coupling development degree is an important basis for measuring the coordinated development of land use and ecological environment in Hohhot.Using the coupling degree of land use and ecological environment and the coupling development degree model,it can be concluded that the coupling degree of land use and ecological environment in Hohhot from 2006 to the present has little fluctuation and has been in good coupling state.While the coupling development degree and coupling degree trend are the same.From the comprehensive evaluation results,the land use and ecological environment in Hohhot are basically coupled and the development trend is good.It shows that the relationship between land use and ecological environment is well handled in the process of economic development,which makes use of land and environmental protection...
