基于公平性的水功能区水环境容量分配方法研究

Water Environmental Capacity Allocation Method for Water Function Area Based on Fairness

摘要: 基尼系数分配法是一种基于公平性为分配原则、以基尼系数为分配依据、综合考虑多个影响因素作用的水功能区水环境容量分配方法。通过东莞市东引运河水功能区内镇街水环境容量分配实例研究显示，基于基尼系数分配法的COD容量分配对工业总产值的基尼系数由等比例分配法分配得出的0.47(不公平)下降到0.29(相对公平)，其余影响因素的基尼系数均处于公平范围。结果表明，基尼系数分配法通过引入多个影响因素进行综合评价，调整分配对象分配容量使基尼系数均符合公平范围，从而使水功能区水环境容量分配更具有公平性和合理性。

Abstract: Gini coefficient distribution method is one for water environmental capacity in the water functional area on the basis of the allocation principle of fairness and the criterion of Gini coefficient, with comprehensively considering a variety of factors. The example research shows that the ratio of COD capacity distribution accounting Gini coefficient of total industry production based on Gini coefficient distribution method is from 0.47 (unfairness) down to 0.29 (relatively fairness) through the water environmental capacity allocation of towns in the Dongyin Canal water function area in Dongguan City, the rest Gini coefficient of factors all are in the scope of fairness. The results display that, all Gini coefficient is in the range of fairness by more factors introduced to comprehensively evaluate and the distribution capacity of objects adjusted for Gini coefficient distribution method. Also, the water environmental capacity allocation in the water function area is more fair and reasonable.
