基于COD水环境剩余容量的流域生态补偿研究

Study on Watershed Ecological Compensation Based on COD Water Environment Residual Capacity

本文从工业利用价值的角度,提出了一种基于剩余COD水环境容量的生态服务价值计算方法,研究了流域生态补偿机制;利用一维断面控制模型核算了研究范围的COD理想水环境容量,并结合研究范围污染物的排放量以及当地GDP,估算了剩余的COD水环境容量及其价值。以左江流域崇左市区域为案例分析,利用该方法计算了该地区剩余环境容量的价值,结合环境和经济要素确定了流域生态补偿的系数,为崇左市流域生态补偿的标准提供了重要的参考,同时也对该流域的水资源保护和环境管理提供了确立长效补偿机制的依据。

Ecological Compensation has attracted considerable attention as an economic stimulation for promoting ecological resource management recently.To balance the economic development unfairness between up and downstream,in a manner,which cause by different administrative strength and range of environmental conservation,a new computing method of ecological service value was put forward,and it provide rationality of mechanism for watershed ecological compensation reference.We use one dimensional section controlling ideal models to compute the COD water environment capacity in selected scope,combine with the city's pollutant emission and Gross Domestic Product,the COD water environment residual capacity and the ecological service value were calculated.The Chongzuo City stream segment,which belongs to Zuojiang river basin,was taken as study area to make case analysis.The COD water environment capacity and ecological service value in this area was counted.Finally,the compensation coefficient was determined by the condition of city's wastewater discharge and economic development.This discovery illuminates the significant of constructing the mechanism of ecological compensation.And it could provide the long-term accordance of resource conservation and environmental management pattern for the official.
