摘　　要：为解决突发性泥石流灾害对水源造成的污染,分析突发性泥石流灾害对水源污染的影响并提出控制方法。利用内梅罗综合污染指数法评价水源污染情况,获取泥石流发生前后的水质评价结果,得出地表水体和地下水体污染为突发性泥石流灾害造成水源污染的原因。为控制水源污染,分析突发性泥石流灾害后水源污染特征,得到水源中不同状态氮元素的转换方式,划分水源污染区域控制单元,优化水源污染控制方案。实例分析结果表明:在经过水源污染控制后,突发性泥石流灾害对于当地水源的污染极小,验证了水源污染控制方法的有效性。In order to solve water source pollution caused by sudden debris flow disaster,the influence of sudden debris flow disaster on water source is analyzed and the control methods are put forward.The Nemerow comprehensive pollution index method was used to evaluate the water source pollution,and the water quality evaluation results before and after the debris flow occurred were obtained.It was concluded that the pollution of surface and underground water bodies was the cause of water source pollution caused by sudden debris flow disasters.In order to control water pollution,the characteristics of water pollution after the sudden debris flow disaster were analyzed,the conversion modes of nitrogen elements in different states were obtained.The regional control units of water pollution were divided and the water pollution control scheme was optimized.The result of case analysis shows that after water pollution control,the pollution of local water source by sudden debris flow disaster is very small,which verifies the effectiveness of water pollution control method.
