湖北汉江流域水资源承载力研究

以湖北汉江流域为研究区域,构建了区域水资源承载力评价指标体系,并运用动态因子分析法对该流域9个湖北城市的2006年-2010年水资源承载力进行了定量评价研究。结果显示:研究期内,湖北汉江流域水资源承载力呈现较明显的区域差异特征:武汉市的水资源承载力的综合水平在区域内处于领先地位;神农架林区、襄阳市、孝感市和仙桃市平均综合排名相对靠前,均为正值;荆门市、天门市、十堰市和潜江市平均综合得分均为负值,排名较靠后。总体上,湖北汉江流域水资源承载力发展态势不容乐观,应积极采取相应措施提高各地区及整体的水资源承载力状况,从而促使水资源、社会、经济可持续稳定发展。

Study of Water Resources Carrying Capacity in the Hanjiang River Basin of Hubei

An evaluation index system of regional water resources carrying capacity was developed in the Hanjiang River Basin of Hubei Province, and the dynamic factor analysis was used to perform a quantitative study of the water resources carrying capacity in nine cities within the river basin. The results showed that the water resources carrying capacity in the Hanjiang River Basin varies significantly in different cities such that Wuhan is the leading city in terms of water resources carrying capacity followed by Shennongjia forest region, Xiangyang, Xiaogan, and Xiantao, whereas Jingmen, Tianmen, Shiyan, and Qianjiang have weaker water resources carrying capacity. In general, the development trend of water resources carrying capacity in the Hanjiang River Basin of Hubei Province was not optimistic, and the corresponding measures should be conducted to improve the water resources carrying capacity, and thereby promoting the sustainable and stable development of water resources, society, and economy.
