摘　　要：从经济、社会和环境系统的整体效益出发,建立了一种定性与定量相结合描述判断矩阵的多指标决策的排污总量分配层次结构模型,并以南方某市化学需氧量总量控制为例说明这种模型的具体运用。该模型在综合分析了各项评价指标后,将求得的各区相对于区域允许排污总量这一总目标的权重之比,作为各区允许排污量之比,然后按此比例在各区间进行排污总量分摊。结果表明,该方法克服了等比例分配的不公平性及排污总量控制系统的不确定性,又兼顾了各区间的实际差异,为该市实行排污总量控制提供了科学依据。With the overall benefits of economic, social and environmental system, a hierarchy structure model for total amotmt distribution of drainage water pollutant was put forward, which used multi indexes decision method and combined qualitatively with quantitatively describing judgment matrix. As an example of the practice application of the model, the model was applied to a southern city in defining the total amount distribution of drainage water pollutant.~ After various indexes were comprehensively evaluated, the weighted ratio of the permitted total arr^unt of pollutants discharged for each sub-region and target permitted total amount of pollutants discharged of the region was obtained. The weighted ratio was used as the permitted proportion of the amount of pollutants discharged for each sub-region. The total amount of water pollutant discharged for each sub-region should be shared according to this proportion. The results showed that the new model overcame the unjustness due to using the equal proportion distribution method and the uncertainty of the system controlling total amount of water pollutant discharged. The differences among sub-regions were taken into account, and the scientific basis for total amount control in the city was provided.
