摘　　要：随着人类社会经济的快速发展,城市水问题越来越突出,水资源承载力是反映水资源供需矛盾的一个重要方面。根据水资源承载力的影响因素并参照全国水资源供需分析中的指标体系,选取其中10个指标,运用主成分分析对浙江省11个地市水资源承载力大小进行计算,基于计算的结果,应用Ex-cel软件对其综合得分进行排序,并运用Gis编制出浙江省水资源承载力大小的分布图。结果表明:浙江省水资源承载力整体较小,各地市差异较大;杭州市最小,宁波市次之,其它各地市的承载力相对较高。简要分析各地市的水问题,提出相应对策,对其发展规划具有一定的参考价值。With the rapid development of human society and economy, urban water problems are becoming increasingly prominent, Water resources carrying capacity is an important aspect,which reflects water supply and demand.According to water resources carrying capacity factors and indicator system of the national water supply and demand analysis, using principal component analysis, this paper selected 10 indicators to calculate water resources carrying capacity of 11 cities in Zhejiang Province. Based on the results of the calculation, it used Excel software to sort its composite scores,and with Gis,the maps out the distribution of water resources carrying capacity of Zhejiang province.The results showed that: the overall water resources carrying capacity in Zhejiang Province was low,every city was quite different;The scoring of Hangzhou city is Minimum and ningbo city followed, carrying capacity of other citys of the province is relatively high.Then this paper analysed water issues in every city briefly, and proposed appropriate measures with some reference value to its development plan.
