珠三角地区水环境承载力综合评价模型研究

针对珠三角地区水环境承载力问题进行研究,从区域水环境承载力所涉及的水资源系统、供水用水系统、水环境污染系统、社会和经济系统、各产业用水指标等多个领域中选取多个指标,构建区域水环境承载力的评价指标体系,利用基于粗糙集理论的属性约简法对指标进行约简,得到较为精简的指标体系;利用Topsis评价法对区域水环境承载力进行了评价,分析了珠三角地区八个城市的水环境承载力,为区域水环境的管理和水污染的控制提供理论基础。

Evaluation Model on Water Environment Carrying Capacity for Pearl River Delta Region

The water environment carrying capacity of Pearl River delta region is analyzed .Some indexes are selected from many fields ,such as the water resources system ,water supply system ,water environment system ,social and economic sys-tem and water indexes of industrial consumption .The attribute reduction method based on rough set theory is used to reduce the indexes ,and the reduced index system is obtained .The regional water environmental carrying capacity is evaluated by the Topsis evaluation method and water environment carrying capacity of eight cities in the Pearl River delta region is ana-lyzed .This study can provide theoretical basis for the management of regional water environment and water pollution control .
