中文摘要：

以湖北省为研究区域,采用水资源负载指数法,在Arc GIS软件的支持下评价了湖北省各城市和各分区的水资源利用程度及开发潜力,定量揭示了不同地区人口-经济规模和水资源量之间的平衡关系。结果表明：整体上,湖北省多年平均水资源负载指数为7.31,水资源利用程度较高,进一步开发的潜力较小。在城市尺度上,神农架林区、恩施自治州、十堰市和咸宁市等城市水资源潜力较大,其他城市水资源潜力较小;在分区尺度上,鄂西南地区水资源潜力较大,江汉平原水资源潜力较小。研究成果将为该地区合理开发水资源、制定中长期生态环境保护和社会经济发展规划提供科学依据。

英文摘要：

This paper adopted water resource carrying capacity index,evaluated the utilization degree and exploitation potential of water resources in cities and regions in Hubei Province using Arc GIS software,and quantitatively described the relationship between population-economy and water resources quantity in different areas. The results indicated that,generally,the average water resource carrying capacity index of Hubei Province was 7. 31 during the period of 2008 to 2013,which showed that the utilization degree of water resources was at a high level and the exploitation potential was low. On the city scale,water resources potential of Shennongjia Forest Region,Enshi Autonomous Region,Shiyan City and Xianning City were higher,and others were lower. On the area scale,water resources potential in Southwest of Hubei was higher,and water resources potential in Jianghan Plain was lower. The research results could provide scientific references for Hubei Province to exploit water resources appropriately and set environmental protection and economic development planning in medium and long term.
