【摘要】：在分析国内外水资源利用效率相关研究基础上,选取用水结构、去变异化农业用水效率、万元工业增加值用水量等5个指标,通过对地区指标数据的聚类分析,采用投影寻踪和遗传算法优化构建水资源利用效率评估模型。以2012年我国299个地级城市作为研究区域,将其水资源利用效率分为五个等级,进行我国水资源利用效率地区差异性研究,研究表明我国城市水资源利用效率地区差异性显著,水资源短缺和经济较为发达的华北和华东地区水资源效率较高,水资源丰富和经济较为落后的西部地区水资源利用效率较低,并对水资源利用效率前后10名的城市进行主要影响因子进行分析,为提高地区水资源利用效率提供依据。
[Abstract]:On the basis of analyzing the related research of water resources utilization efficiency at home and abroad, this paper selects five indexes, such as water use structure, devariant agricultural water use efficiency, water consumption of ten thousand yuan industrial added value, etc., through the cluster analysis of regional index data. Projection pursuit and genetic algorithm are used to optimize the evaluation model of water resources utilization efficiency. In 2012, 299 prefecture-level cities in China were taken as the research areas, and their water resources utilization efficiency was divided into five grades. The regional differences of water resources utilization efficiency in China were studied. The results showed that the regional differences of water resources utilization efficiency were significant in China. North and East China, where water resources are short and economically more developed, have higher water resources efficiency, while the western regions, which are rich in water resources and relatively backward in economy, are less efficient in water resources utilization. The main influencing factors of 10 cities before and after the utilization efficiency of water resources were analyzed to provide the basis for improving the efficiency of water resources utilization in the region.
