• 摘要：从经济、社会和环境系统整体效益出发,将环境基尼系数应用于总量控制分配中,分别以人口和工业增加值等作为湖泊流域内基尼系数分配的指标,建立了一种定性与定量相结合描述湖泊流域分区水污染物排放总量分配的层次结构模型.该模型综合考虑了各项评价指标,以区域允许排污总量为基础,依据环境基尼系数调整各分区允许排污量的权重比,并依此比例在各分区间进行排污总量分配.同时,以汤逊湖流域为例,根据流域内经济、社会和环境系统的实际特点,以工业增加值为主要限制指标,调整分配方案,计算出该流域水污染物排放总量的分配结果.结果表明,本研

• Abstract：To maximize the integrated economic,social and environmental benefits,a hierarchical model is developed for both qualitative description and quantitative analysis of the distribution of total water pollutants allowed to be discharged among the sub-areas of a lake basin by applying the environmental Gini coefficient to the distribution. Population and industrial value-added were used as indicators for distribution of the Gini coefficient in the lake basin. Constrained by allowable total amount of pollutant discharged,the model readjusts the weight ratio of the allowable amount of pollutant discharged between sub-areas in accordance with the environmental Gini coefficient,then distributes the amount of pollutant to each sub-area on the basis of the readjusted weight ratio by considering the relevant evaluation indicators comprehensively. The model is applied to the case study area,TangxunHu Lake Basin,to achieve a distribution plan for water pollutants. In the light of the specific conditions of the economic,social and environmental systems of the case study area,a plan to reduce in the amount of pollutants discharged is modified by running the model with industrial value-added as a major restriction indicator,in (order to achieve equal and reasonable distribution of pollutants. The results indicate that the proposed approach is suitable for overcoming the inequity of amount of pollutants distributed by industries with equal rations and considering actual differences between sub-areas.
