城市土地集约利用效益耦合协调度分析——以咸宁市为例

Coupling Coordination Degree Analysis of Urban Land Intensive Use Benefits in Xianning City

借助系统科学理论与方法,构建了城市土地集约利用社会经济效益与生态环境效益之间的耦合协调理论模型,对咸宁市1999—2008年城市土地集约利用社会经济效益、生态环境效益、社会经济效益与生态环境效益耦合度和耦合协调度进行了实证分析。研究结果表明:①城市土地集约利用社会经济效益处于快速上升的态势,生态环境效益呈现出在波动中稳定上升的趋势;②从总体上看,城市土地集约利用社会经济效益与生态环境效益耦合度处于拮抗发展状态,耦合度呈现出缓慢上升的态势;③城市土地集约利用社会经济效益与生态环境效益耦合协调度经历了低度协调耦合、中度协调耦合和高度协调耦合3个阶段。

With the theory and method of general system science, the paper, by taking Xianning City as a case study, established coupling coordination theoretical models of socio-economic benefits and eco-environment benefits of urban land intensive use, then analyzed socio-economic benefits and eco-environment benefits of urban land intensive use, coupling degree and coupling coordinative degree between urban land intensive use socio-economic and eco-environment by using the statistical data during 1999--2008. The results showed that： ①The socio-economic benefits of urban land intensive use increased rapidly, however, the eco-environment benefits of urban land intensive use increased in a fluctuation. ② In general, the coupling degrees of urban land intensive use socio-economic benefits and eco-environment benefits was at an antagonism development stage, the coupling degrees increased slowly. ③The coupling coordination degree of urban land intensive use socio-economic benefits and eco-environment benefits experienced low coordination level, moderate coordination level and high coordination level.
