| 摘 要： | 文章将熵权法与综合评价法有机结合,建立了南京市水资源可持续利用评价指标体系的层次结构模型,并通过熵权法确定权重,对南京市水资源可持续的利用进行评价。结果表明,2000~2007年南京市水资源利用综合指数(ISU)水平良好,总体呈上升趋势,涨幅相对缓慢,仍有较大潜力;在2000~2002年和2006~2007年,水资源可持续利用水平两次呈现小幅的下降趋势,可见南京市水资源可持续利用水平较为不稳定,易受多重因素影响。分系统对比分析得出:科技与教育、人群健康、水资源利用等方面对水资源的可持续利用贡献率较高,但经济发展、社会文化等方面稍显不足,特别是生态环境方面贡献率最低,需进一步加大上述薄弱方面的投入与管理。

| Abstract: | In this paper,a hierarchical model of evaluation index system was established by combining Entropy Weight Method and Comprehensive Evaluation Method.The weights were determined by means of Entropy Weight Method to evaluate sustainable utilization of water resources in Nanjing City.The results showed that,during 2000~2007 the Composite Index of Sustainable Utilization of Water Resources(ISU) was good,being slowly increasing with rather potential.It dropped twice in small scale during 2000~2002 and 2006~2007 ... |
