西宁市土地利用与生态环境耦合关系

Coupling Relationship between Land Use and Eco-environment in Xining City

以西宁市为研究区,通过构建土地利用与生态环境两个子系统之间的耦合协调度和耦合发展度模型,对西宁市2004-2014年间的土地利用与生态环境耦合关系进行了研究.结果表明:2004-2014年西宁市土地利用与生态环境综合指数均呈现整体上升,微小波动的趋势;从总体上看,西宁市土地利用与生态环境耦合发展度呈缓慢上升的态势,两者耦合程度较高.土地利用与生态环境耦合发展度大体经历了中级耦合-良好耦合-优质耦合3个阶段.研究期内,两者耦合关系呈现良性发展的态势,但还应继续加大土地开发利用与生态环境保护的投入力度,维系两者同步发展的状态,为地区经济持续健康发展提供保障.

The Xining City was taken as a research area, by constructing the coupling coordination degree model and the coupling development degree model between the Land Use and the two sub-systems of ecological environment, a study is car- ried out to investigate the coupling relations between the land use and the eco-environment during 2004-2014. The results show that： The comprehensive index of land use and eco-environment in Xining undergoes an overall slow gradual rise with slight fluctuation in 2004-2014; In general, the coupling development degree of land use and eco-environment in Xining is taking a slowly rising trend, and the degree of coupling is high,The coupling development degree of land use and eco-environment has experienced three stages： intermediate coupling, good coupling and high-quality coupling stage. During the research period, the coupling relationship between the two shows a benign development trend, yet still greater investment is needed in this regard so as to maintain a synchronous development between them and therefore to safeguard the sustainable healthy development.
