【摘要】 以控制流域断面水质为目标,在排污权交易市场中引入交易比率,以解决排污权交易带来局部水质恶化的热点问题。以江苏省无锡市社渎港流域为研究区域,模拟该流域主要点源化学需氧量(COD)的排污权交易,探讨交易比率对排污权交易政策效果的影响。模拟结果显示,交易比率会促使排污布局向上游迁移,但交易前后控制断面的水质不变,可避免热点问题的出现。更多还原

【Abstract】 To ensure the water quality of the control section of a watershed,the trading ratio is introduced in order to prevent regional water quality deterioration after water pollution rights trading,which is a hot spot problem.The COD trading in the Shedugang River Basin in Wuxi,in Jiangsu Province,was modeled to explore the influence of the trading ratio on the effect of the water pollution rights trading policy.The results show that the trading ratio can promote the distribution of discharge moving upwards,and the water quality of the control section remained unchanged after trading,which helps to avoid the hot spot problem.更多还原
