摘要
为综合评价金泽水库及上游来水的水体环境质量,选择太浦河沿线及金泽水源地9个监测点,根据9项特征性水质污染指标,运用TOPSIS模型,对其水质进行综合评价。通过各断面Li值分析,水体质量由好到差依次为:金泽水库出水(0.5991)>太浦闸下(0.5488)>库中央栈桥(0.3607)>平望大桥(0.1900)>引水河入库桥(0.1655)>金泽水库取水口(0.1101)>黎里东大桥(0.0786)>芦墟大桥(0.0545)>金泽水文站(0.0399)。通过与单因子评价法、内梅罗指数法对比,明确TOPSIS模型优劣。TOPSIS模型可为金泽水库及上游来水多指标的水质综合评价及治理提供科学依据。
In order to comprehensively evaluate the environmental quality of Jinze Reservoir upstream inflows,selecting nine monitoring points along the Taipu River and Jinze water source,TOPSIS model is used to evaluate the water quality according to the nine characteristic water pollution indexes.Through the relative proximity analysis of each section,the order of water quality from good to bad is outflow of Jinze Reservoir (0.599 1)>Taipu Sluice (0.548 8)>reservoir central trestle (0.360 7)>Pingwang Bridge (0.190 0)>bridge of diversion river into reservoir(0.165 5)>Jinze Reservoir water intake(0.1101)>Lilidong Bridge(0.078 6)>Luxu Bridge(0.0545)>Jinze Hydrological Station(0.039 9).By comparing with single factor evaluation method and Nemerow index method,the advantages and disadvantages of TOPSIS model are clarified.The TOPSIS model can provide a scientific basis for comprehensive evaluation and treatment of Jinze Reservoir and upstream water quality.
