摘要
在界定水环境综合承载能力概念的基础上,建立了能定量反映出经济社会系统、水资源系统、水环境系统之间相互作用关系的"经济社会-水资源-水环境"复合系统模型;以"支撑最大经济社会规模"为目标函数,以"维系良好水环境状况"为约束条件,并考虑复合系统模型约束、水量约束和其它约束条件,建立了分区式水环境综合承载能力计算模型;提出承载程度的评价方法和标准;运用上述模型和方法,计算和评价了淮河流域71个单元的水环境综合承载能力和承载程度。
A compound model for studying interactions amongst socioeconomics,water resources,and water environment in the Huaihe River basin is developed based on the determinate notion of carrying capacity of water environment.According to the constraint conditions of supporting the maximum size of socioeconomic activity in a region,maintaining good water environment,the compound system and the water availability,etc,a zonal water environment carrying capacity model is developed.The carrying capacity evaluation method and criteria are also proposed.The zonal model is applied to 71 computational elements in the Huaihe River Basin,and the results of carrying capacity of water environment are assessed using the proposed evaluation method and criteria.
