珠江三角洲广义水环境承载能力评价

Evaluation on generalized water environment carrying capacity in Pearl River Delta

根据广义水环境承载能力的定义,在深入分析珠江三角洲水环境特点的基础上,构建了广义水环境承载能力评价指标体系,采用基于改进熵值法赋权的集对分析模型,综合评价了水资源子系统、社会经济子系统和生态环境子系统和区域水环境的承载能力;最后,根据评价结果,提出了改善研究区域水环境承载能力的建议。

In this paper,based on the concept of generalized water environment carrying capacity(WECC),its corresponding assessment index was constructed according to the practical situation of water environment in Pearl River Delta.The generalized water environment system is composed of water resource sub-system, socioeconomic sub-system and eco-environment sub-system.Regional WECC in Pearl River Delta and its three sub-systems were comprehensively appraised adopting the set pair analysis(SPA) model based on the impr...
