摘要
选取31个省级单位最新数据,提炼出7大类共计25项反映水资源可持续利用的评价指标体系,运用主成分分析法和DEA模型评价了我国水资源可持续利用的能力。研究结果表明:我国近74.2%的省份水资源可持续利用能力欠佳,呈阶梯状分布,这主要是由于水资源与社会经济、水环境容量、农业灌溉、城市发展、生态保护与可持续利用的不协整所导致的,但仍有很大的发展潜力。
By selecting the latest data from 31 provincial units, seven kinds( 25 in total) of evaluation indexes of sustainable utilization of water resources are extracted. The principal component analysis and DEA are employed to evaluate the sustainable utilization of water resources in China. The research results show that the sustainable utilization capability of water resources of nearly 74. 2% of China's provinces is poor,and it is distributed like a ladder. The reason is mainly resulted from the noncoordination of sustainable use of water resources and socio-economy, water environment capacity,agricultural irrigation, urban development and ecological protection. However,there is still a large development potential.
