【摘要】 针对目前存在的水环境安全问题,用层次分析法(AHP)建立水环境安全综合评价指标体系,并计算各指标的权重,以评价影响水环境安全系统的主要因素.结果表明:水环境综合评价指标体系22个指标的权重确定中,所占权重最大的5个指标依次为:河流水质级别、河流生态需水压力、城市废污水排放量、河流CODCr质量浓度以及污染物排放强度等.更多还原

【Abstract】 A water environmental safety assessment index system was set up and the weight of each index was calculated by the analytic hierarchy process （AHP） method. The result can be used to evaluate the main factors influencing the water environmental safety system. It was indicated that, among the 22 indexes of the system, 5 indexes with the largest weights were ranked as follows: the grade of river water quality, pressure of ecological water demand of rivers, volume of urban wastewater discharge, COD_Cr concentration of rivers, and discharge intensity of pollutants.更多还原
