| 摘 要： | 依据模糊理论建立了河流水质风险评价模型,通过加权评价和熵值法确定了多个监测序列指标权重,给出了5级水质污染风险等级,评价了渭河干流陕西段污染物序列风险以及区间水质污染风险。结果表明:渭河主干河流中下游水质污染风险较大,上游风险相对较轻。这些研究为河流水质控制与恢复管理提供了依据。

| Abstract: | The paper established a risk assessment model on river water quality according to fuzzy theory,and determined the index weights of multiple monitoring sequences by using entropy method and gave 5 risk grades of water pollution.It also evaluated the risk of river pollutant sequence index and interval risk of water pollution in Shaanxi section of Weihe River.The results showed that water pollution risk in middle and downstream of Weihe River is larger and that in upper reaches is relatively lighter. The research provides basis for the control and recovery management of river water quality. |
