Research on the coupling coordination of land,economy and ecology in Guiyang city
In order to explore the coupling coordination relationship among land intensive use,economic development,and ecological environment in Guiyang,this paper constructs the evaluation system of three subsystems for land,economy,and ecology,and measures the comprehensive score and coupling coordination situation through entropy weight method,principal component analysis,and coupling coordination model.The results show that the land intensive use and economic development in Guiyang have been improving over time,and the ecological quality has been maintained at a good level and is on an overall upward trend.The three subsystems reached the coupling stage in 2018,but compared with the other two,the subsequent score of the ecological sub-environment rose slowly,which made the coupling degree between the subsystems decline.In summary,increasing investment in land,increasing financial expenditure on education,science and technology,and strengthening the awareness of ecological protection responsibility can effectively enhance the overall development among subsystems and promote the high-quality development of Guiyang city.
