基于主成分分析的广东省水资源承载力研究

Study on Carrying Capacity of Water Resources in Guangdong Province Based on Principal Component Analysis

正确地评价区域水资源状况,对促进经济社会的可持续发展具有重要意义。文章运用DPSIR模型构建多因素指标体系,利用主成分分析法对广东省的水资源承载力进行评价,研究表明,2006～2015年间,广东省水资源承载力呈逐年上升的趋势。经济发展、社会进步、科技水平及人们节能减排意识的提高,都能从一定程度上缓解水资源的供需矛盾,减少水资源的压力,提高水资源的承载力。

It is of great significance to the promotion of the sustainable development of economy and society in the correct evaluation of the regional water resources. This paper handles DPSIR model to construct a multi-factor index system and uses the principal component analysis method to evaluate the carrying capacity of water resources in Guangdong province. in order to provide scientific basis for water resources management and rational utilization. The research shows that the carrying capacity of water resources in Guangdong assumed the upgrading trend year after year during 2006-2015. The economic development and social progress, the improvement of sciences and technologies, and the enhancement of the people's awareness of energy saving and emission reduction can alleviate the contradictions between the supply and demand of water resources from a certain extent, reduce the pressure of water resources, and improve the carrying capacity of water resources.
