贵阳市土地、经济、生态耦合协调研究

Research on the coupling coordination of land,economy and ecology in Guiyang city

为探明贵阳市土地集约、经济发展、生态质量的耦合协调关系,本文构建土地、经济、生态三个子系统的评价体系,通过熵值法、主成分分析法与耦合协调模型测算其综合得分以及耦合协调情况。研究发现,贵阳市的土地集约程度与经济发展水平随时间推移不断提高,生态质量一直维持在良好水平且整体呈上升趋势;三者在2018年达到耦合阶段,但相较于其余二者,生态子环境后续得分上涨缓慢,这使得子系统间的耦合度有所下降。综上,加大土地投入、增加教育及科学技术的财政支出、强化生态保护责任意识,能有效提升子系统间的整体发展水平,并促进贵阳市的高质量发展。

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.
