摘　　要：针对目前污水灌溉风险研究中没有对综合环境风险进行研究和没有进行系统的风险识别的不足,提出了应用层次分析法对污水灌溉造成的各类风险进行风险识别。结果表明:污水灌溉造成的各类风险中,土壤——作物的污染风险所占的权重最大,地表水风险次之,人群健康风险居第三,地下水风险、社会与个人财产损失风险分别居第四和第五,大气风险所占权重最小。这与其对环境影响的过程是相符的。According to the present shortage of no research on comprehensive environmental risk and systematic risk identification in the research of sewage irrigation risk, this paper refers to carry out risk identification on sewage irrigation causing diverse risks by using analytic hierarchy process meth- od. It indicates that, among the risks caused by sewage irrigation, the percentage of soil - crop pollu- ted risk is the most important, the surface water polluted risk is the second, the people health risk is the third, the ground water,the property loss risk of society and individual is the fourth and the fifth separately, the atmospheric risk is minimum. It conforms to the process of sewage irrigation impact on environment.
