基于纳污红线的河流排污权优化分配模型

实行水功能区限制纳污红线的水资源管理制度，在理论和实践中必须要建立河流污染物总量控制管理制度，而实行污染物总量控制，首先要确定河流排污权的初始分配方案。结合我国现行流域水功能区划成果，以水功能区作为排污权初始分配主体开展排污权分配研究，提出由河流环境保护部门确定河流总体排污权，首先通过纵向配置将排污权分配给水功能区，然后通过横向配置将初始排污权分配给排污者的一种纵向加横向分配模式。以资源分配的公平性和效率为管理目标，并以污染物总量控制、浓度控制、企业生产连续性等为约束条件，建立了河流排污权多目标分配优化模型。最后利用多目标演化算法对算例进行了求解，验证了方法的可行性，且此分配方式所获得的环境节余容量最大

OPTIMAL ALLOCATION MODEL OF RIVER EMISSION RIGHTS BASED ON POLLUTION LIMITS

To implement the water resources management system of water pollution restriction in water function district,the total control of river pollution management system in theory and practice should be established.The river initial water pollution allocation method is one of the most important systems in the total pollution control.In this study,the water function districts were taken as the main body of initial allocation of emission permits.Meanwhile,the purpose of this article is to try to allocate the emission permits on water function districts based on the existing administrative features in China and the water function planning field.According to this allocation mode,the emission rights should be allocated to the respective water body by the pollution control agency according to the function of water body(vertical configuration),and then the rights be allocated in detail to the dischargers(horizontal configuration).In this model,the fairness and efficiency were regarded as the objective functions.The concentration and total quantity of pollutant were the constraints,and the continuity of the production program of the dischargers was taken into account.At last,we got an example and solved it by multi-objective evolutionary algorithm to verify that the model is viable,and this distribution could get more environmental capacity.
