南京城市化与水资源环境耦合关系实证研究

Empirical Study on Coupling Interaction Between Urbanization and Water Resources Environment in Nanjing

通过建立城市化和水资源环境综合指标体系,利用耦合协调度模型,对城市化水平与水资源环境二者之间的演变规律进行研究,对南京市2000—2012年间的城市化与水资源环境交互耦合作用关系进行了量化分析.结果表明:南京市城市化综合指数呈线性增长趋势,水资源环境综合指数及耦合协调度总体上处于均衡发展态势,虽然近些年两者的协调度出现波动式变化,但总体发展态势良好,在合理可控的范围,需要对出现的协调度下降状况引起重视.

The evolution law of the urban level and water resource environment was studied by establishing the compre- hensive index system of urbanization and water resources and using the model of coupling coordination degree. A quantitative a- nalysis was made on the relationship between urbanization and water resource environment in Nanjing from 2000 to 2012. The results showed that the Nanjing urbanization comprehensive index was a tendency to increase linearly, the comprehensive index of water environment and the coupling coordination degree was generally in the balanced development of the situation. Although in recent years the degree of coordination changed in volatility, the overall developing status was favorable and within a control- lable range, should pay attention to the decline of coordination degree.
