江苏省城镇化进程水平与河湖水系连通耦合协调模式研究

Research of the coupling and coordination model between urbanization level and the interconnected river system network in Jiangsu Province

近年来,我国城镇化水平不断提升,城镇水系问题日趋严重。以江苏省为研究对象,通过建立城镇化系统进程状况和河湖水系连通水平的评价指标体系,采用熵值法求出各项指标的权重,进而利用耦合协调模型计算城镇化与河湖水系连通系统耦合协调度。结果表明:江苏省2004-2014年城镇化水平逐年提升,河湖水系连通水平基本上呈下降趋势。城镇化与河湖水系连通系统经历了低水平耦合阶段和颉抗阶段,并向基本磨合阶段过渡。耦合协调度前期普遍处于较低水平,后期呈上升趋势,故在城镇化过程中要注重城镇化建设与河湖水系连通建设,使二者耦合协调,促进区域人水和谐。

With the rising levels of urbanization in China,the problem of urban water system has become more and more serious in recent years. Taking Jiangsu province as the research object,in this paper the evaluation index system of urbanization system process and the level of interconnected river system network were established,the entropy method was used to calculate the weight of each index,and then the coupling and coordination degrees of urbanization and interconnected river system network were calculated by using the Coupling and Coordination Model. The results showed that,the urbanization level increased year by year from 2004 to 2014 in Jiangsu province,and the level of interconnected river system network was basically declining. The urbanization and the interconnected river system network has undergone the low-level coupling stage and the resistance stage,and transitted to the basic running-in stage. The coupling and coordination degree was generally at a low level in the early stage and ascended in the later stage. As a result,attentions should be paid to the construction of urbanization and the interconnected river system network in the process of urbanization,so that the coupling and coordination of them can promote the harmony of people and water in the region.
