| 摘 要： | 基于水贫困的概念和大连市水资源在资源、途径、能力、利用和环境5个方面的具体状况,选取22个分指标构建了大连市水贫困评价的指标体系,采用水贫困指数法对大连市2001～2009年的水贫困指数进行计算。结果表明:2001～2009年,大连市水贫困指数值总体呈上升趋势,发展势态良好,但各年的值均不高,水资源依然处于较贫困状态;从各子系统得分变化分析,途径、能力和利用得分表现出波动上升趋势,环境得分呈下降趋势以及资源得分波动较大。

| Abstract: | Based on the conception of water poverty and specific situations in resource, access, capacity, use and environment of water resources in Dalian City, the evaluation index system of water poverty in Dalian City was established by using 22 indexes, the water poverty index in Dalian City between 2001 and 2009 were calculat- ed by employing water poverty index method. The results indicated that from the year of 2001 to 2009, the overall trend of water poverty index values in Dalian City was increasing, and the developing state was better, however, the values in each year were not high, and the water resources still in a much poorer state; from the score varia- tion analysis of each subsystem, the score of access, capacity and use increased fluctuating, environment score showed a decrease trend, meanwhile, the score of resource fluctuated obviously. |
