丰水区城镇化进程与水资源利用的关系——以江苏省为例

目的]以江苏省为例,研究丰水区城镇化发展与水资源开发利用的主要影响因素、变化特征以及两者响应关系,以实现城镇化发展与水资源利用的协调。方法]运用熵权法构建江苏省城镇化综合发展水平和水资源开发利用综合潜力评价指标体系,并进行响应度关系模型构建和相关性分析。结果]研究期间,尤其是2008—2012年,江苏省处于经济快速发展时期,人口城镇化和空间城镇化水平高于经济城镇化和社会城镇化,城镇化发展不协调;伴随城镇化进程的推进,江苏省水资源开发利用水平呈上升趋势,水资源禀赋逐年降低,水资源利用水平稳步提升,但水资源污染程度也在加深。2004,2009,2010年,江苏省水资源系统在一定程度上制约了城镇化的发展。结论]城镇化进程与水资源利用存在一定的响应关系,目前江苏省正面临提高城镇化发展协调性的任务,必须改变传统的外延型扩张模式,合理高效地利用水资源。

Relationships Between Urbanization and Utilization of Water Resource in Water-rich Areas- A Case Study in Jiangsu Province

Objective] We took Jiangsu Province as a case study to investigate the key influence factors, the variation characteristics and the relationships between urbanization development and water resources development and utilization in order to coordinate the development of urbanization and utilization of water resource.Methods] Evaluation index system of the comprehensive development level of urbanization and potential development and utilization of water resources in Jiangsu Province was constructed by entropy weight method. The response relationship model and correlation analysis was employed.Results] During the study period, especially from 2008 to 2012, Jiangsu Province was in a period of rapid economic development. The economic and social development level was lagged behind the population and area increase, and the urbanization was not coordinated. With the advance of urbanization process, the level of water resources development and utilization increased steadily, however, the water resource amount decreased and the water resources pollution increased year by year. The shortage of water resources restricted the development of urbanization in 2004, 2009, 2010.Conclusion] There is a certain response relationship between urbanization process and water resources usage. At present, Jiangsu Province is facing the task of improving the coordination of urbanization, it need to reform the traditional expansion of urbanization and to use the water resource rationally and efficiently.
