城市化与生态环境变迁的耦合演进分析——以新疆喀什市为例

An Evolutionary Study of Coupling Between Urbanization and Ecological Environment Change——Case Study of Kashgar City in Xinjiang

城市是一个复杂的庞大系统,本文选取城市化和生态环境两个子系统建立指标体系,利用数学模型对喀什市2006—2011年城市化与生态环境系统耦合演进趋势进行定量分析。分析结果表明:2006年城市化与生态环境耦合度为0.807,是最低,2007—2011年城市化与生态环境耦合协调度分别为0.855、0.946、0.941、0.976、0.875,城市化与生态环境协调度总趋势为逐渐增长,城市化与生态环境耦合协调以中度协调为主。

City is a complex huge system.This article selected two sub-systems of urbanization and ecological envi-ronment to establish the index system,and made a quantitative analysis of Kashgar City’s systematic evolutionary coupling trend from 2006 to 2011 with mathematical model.The results showed that the coupling between urbanization and ecolo-gical environment was 0.807 in 2006,which was the lowest;from 2007 to 2011,the coupling was 0.855,0.946,0.941,0.976 and 0.875 respectively;and in general,the coupling,which was mainly moderate,was improving gra-dually.
