中国正处在城市化快速发展阶段,而水资源短缺逐渐成为城市迅速发展的制约“瓶颈”。为科学衡量城市水资源的保障程度,建立了城市水资源可持续度模型,并以全国31个省级区域为例进行了分析。结果显示,在充分考虑经济发展、城市建设等多重目标的基础上,全国各省域城市水资源可持续度可分为高可持续、中可持续、低可持续、亚可持续等4类区域,且结果与给水资源的赋存状况存在一定差异。
The shortage of water resources was becoming the bottlelock for cities' developing in China which was in the period of quick urbaniza tion. In order to measure bitterly the guarantees degree of water resoureces for cities, this article set up the sustainability model. Taking 31 provinces in China as an example, it analyzed it deeply. Conclusion could be drew that the provinces in China could be derided into four kinds, which were different from the natural condition of water resource.
