摘要
以南京市所辖区域作为研究区,根据2003—2010年水资源利用的有关资料,采用主成分分析法和熵权法对该研究区水资源可持续利用程度进行综合评价,并运用聚类分析法对评价结果进行对比分析。结果表明:研究区2003—2010年期间水资源可持续利用水平总体呈上升趋势,但从聚类分析结果看,水资源可持续利用程度的改善幅度并不大,说明目前南京市水资源可持续利用问题依然严峻。
The principal component analysis method and the entropy weight method were used to evaluate the sustainable utilization of the water resources in Nanjing City, based on water resources utilization data from 2003 to 2010. The clustering analysis method was used to compare and analyze the evaluation results. The results show that, during the period from 2003 to 2010, the sustainable utilization level of water resources showed an increasing trend in general. Clustering analysis shows that the increase is not significant, indicating that there are still serious obstacles to sustainable utilization of the water resources in Nanjing City.
