摘要:

利用湖北省17个地市(州)2003~2008年相关数据,运用标准显示性比较优势指数(NRCA)计算各地区各部门水资源利用的规模、效益优势指数和比较优势度,经分类时空分异分析提出:自然条件、自然资源禀赋、经济发展水平及用水效率是湖北省地区生产用水比较优势的驱动因子;城市化发展水平是生活用水比较优势的主要影响因素。此外,灌溉用水优势区域为江汉平原区;林牧渔业用水优势区域主要分布在沿江地带及山区林牧渔业发达区域;工业用水优势区域为武汉、黄石、十堰等传统工业区。证实了NRCA在水资源优势评价方面的可行性。

Abstract:

As to the data of water utilization in seventeen cities of Hubei Province from 2003 to 2006 and the comparative advantage principle(CAI),the scale advantage indices (SAI) and benefit advantage indices (BAI) were calculated with the normalized revealed comparative advantage index (NRCA) model.The seventeen cities were clustered by the comparative advantage value,and the temporalspatial difference was analyzed,and we find that the driving factors which brought on the fluctuation of the comparative advantage index of productive water,were natural condition,natural resource, population,economic development level as well as water utilization benefit;and that of residential water was urbanization level.The results showed that the superiority regions of irrigation water utilization were in Jianghan Plain;the superiority regions of forestry,livestock and fisheries water utilization were in areas along the Yangtze River and herbage regions of Hubei Province;and the superiority regions of industrial water utilization were in the traditional industrial district of Hubei Province,such as Wuhan,Huangshi and Shiyan.The results show the feasibility of NRCA method in water resources advantage assessment
