以湖北省为研究区域,在前人研究基础上,从人口数量压力、水资源数量压力、水环境压力、水资源技术压力、水资源经济压力和水资源紧缺压力6个角度对2009年湖北省各主要地市的水资源压力指数进行了计算和分析。结果表明:湖北省内,武汉市水资源压力最大,鄂州次之,宜昌和黄石市等水资源压力相对较大,黄冈、荆州和十堰市等水资源压力相对较小;武汉市的人口数量压力和水资源紧缺压力大,鄂州市的水资源数量压力大,宜昌和十堰的水环境压力大,随州和黄冈市的水资源技术压力大,孝感市水资源经济压力较大。

Assessment of Water Resources Pressure Indexes of Main Cities in Hubei Province

In this paper, on the basis of previous studies, we calculated and analyzed water resources pressure indexes of main cities in Hubei Province in 2009 from the aspects of population quantity, water resources quantity, water environment, water resources technic, water resources economy and water resources lack. The results obtained from comprehensive indexes showed that the water resources pressure was the most serious in Wuhan, Ezhou followed by, and the water resources pressure was more serious in Yichang and Huangshi, while less pressure was in Huanggang, Jingzhou and Shiyan, etc. The sub-entry index results indicated that the population quantity pressure and water resources lack pressure was more serious in Wuhan, water resources quantity pressure was more serious in Ezhou, water environment pressure was more serious in Yichang and Shiyan, water resources technic pressure was more serious in Suizhou and Huanggang, water resources economy pressure was more serious in Xiaogan.
