基于耦合协调度模型的都匀市土地利用变化与经济增长协调性研究

目的]土地利用与社会经济发展之间关系的研究对于新型城镇化建设具有重要的意义;研究分析都匀市土地利用与社会经济发展的耦合关系,探究如何合理利用土地资源,更好推动区域经济发展。方法]以贵州省第一批新型城镇化试点城市都匀市为研究区,从土地利用和社会经济两个系统入手,采用层次分析法建立综合评价指标体系,并运用耦合协调度模型对都匀市土地利用与社会经济发展的协调度进行了测算。结果] 2009—2016年都匀市土地利用与社会经济发展协调度呈不断上升趋势,协调度等级由轻度失调上升到初级协调状态;协调发展类型由社会经济发展滞后型变为土地利用滞后型。结论]都匀市土地利用与社会经济发展之间,总体协调发展度水平仍旧较低,且土地利用落后于社会经济发展。结合都匀市今后发展,建议制定合理的土地利用开发利用规划,加大对建设用地挖潜的力度,同时注重耕地保护。

RESEARCH ON COORDINATION OF LAND USE AND ECONOMIC GROWTH IN DUYUN BASED ON COUPLING COORDINATION DEGREE MODEL

The study of the relationship between land use and socio economic development is of great significance to the construction of new urbanization. This research is planned to study and analyze the coupling relationship between land use and socio economic development in Duyun, and explore how to make rational use of land resources, so as to promote regional economic development. Taking Duyun, Guizhou, one of the first batch of new urbanization pilot cities, as the research area, from the two systems of land use and social economy, this research established a comprehensive evaluation index system by adopting the analytic hierarchy process as well as calculated its coordination degree of land use and socio economic development based on the coupling coordination degree model. The results show that the coordination degree of land use and socio economic development in Duyun is on the rise from 2009 to 2016, and the degree of coordination is increased from mild maladjustment to primary coordination. The coordinated development has changed from the lagging of social economic development type to the lagging of land use type. The overall level of coordinated development between land use and socio economic development in Duyun is still low, and the land use lags behind socio economic development. In terms of future development of Duyun, it should work out a reasonable plan for land use and development, make more efforts to tap the potential of construction land, and pay attentions to protect the cultivated land at the same time.
