摘要
以滦河承德段为研究对象,先对该河段的9个断面采用单因子指数法和灰色关联分析法进行了水质评价,再根据水功能区特征划分控制单元,采用一维模型核算该河段的水环境容量,最后基于经济、环境、公平原则,采用等比例分配法对各行政单元进行水环境容量初始分配,选取GDP、区域面积、人口作为基尼系数的分配指标,并利用各指标下的基尼系数对分配方案进行了评价及优选。结果表明:滦河承德段水质较优,COD、NH_(3)-N、TP 3种污染物的水环境容量分别为5203.61t/a、505.71t/a、72.92t/a;在环境容量分配中,4种分配方案均满足相对公平要求,且环境效益权重较大的方案更为合理。
Taking Chengde section of Luanhe River as the research object,the water quality of 9 sections was evaluated by single factor index method and grey correlation method.Then the control unit was divided according to the characteristics of water function area,and the water environment capacity of the research section was calculated by one-dimensional model.Finally,based on the principles of economy,environment and equity,the equal proportion allocation method was adopted to initially allocate the water environment capacity of each administrative unit.GDP,regional area and population were selected as the distribution indicators of Gini coefficient,and the distribution schemes were evaluated and optimized by using the Gini coefficient under each indicator.The results show that the water quality of Chengde section of Luanhe River is better,and the water environmental capacities of COD,ammonia nitrogen and total phosphorus are 5 203.61 t/a,505.71 t/a and 72.92 t/a,respectively.In the allocation of environmental capacity,the four allocation schemes meet the requirements of relative fairness,and the scheme with large weight of environmental benefits is more reasonable than other schemes.
