摘　　要：利用水足迹的研究方法对江苏省真实的水资源利用情况进行识别,同时结合相对＂脱钩＂＂复钩＂系统耦合理论,从水资源消耗与水环境压力两个方面对江苏省2000~2009年的水资源利用情况与经济增长间的关系进行评价.研究表明,2009年江苏省的水足迹为773.77亿m3,总体呈缓慢增加趋势,其中农业用水与工业用水是水足迹的主要组成;同时,水资源利用效率不断提高,10年间增长了2.77倍;全省经济增长与水资源消耗评价结果中有1/3的年份为强＂脱钩＂状态,2/3的年份呈弱＂脱钩＂状态,经济增长与水环境压力的评价结果中强弱＂脱钩＂交替出现,水环境的压力依然存在.江苏省水资源利用还没有达到理想水平,在水资源利用与经济增长协调发展方面应采取更有效措施.The paper attempted to employ the water footprint approach to calculate the situation of water resource in Jiangsu Province between 2000 and 2009,and investigate the changes of water utilization and water pressure in economic growth by introducing the conceptual model of ＂re-linking＂ and ＂de-linking＂.The total water footprint of Jiangsu was on the slightly rise from 699.82 in 2000 to 773.77 billion cubic meters in 2009,mainly consists of the agricultural water and the industrial water.Simultaneously,the water utilization level kept continuous growth,increasing by 2.77 times in the last decade.However,the weak ＂de-linking＂ and strong ＂de-linking＂ status between water resource and economic growth accounted for two-thirds and one-third of the sample years,separately.The alternative change of weak ＂de-linking＂ and strong ＂de-linking＂ status showed the pressure of water resource still existed in the process of rapid industrialization and urbanization,and,therefore,strategies should be adopted for more vigorous economic development and consistent water resource use in Jiangsu.
