中文摘要：

暴雨山洪灾害是影响山区中小流域的重大自然灾害之一。特别是对山地景区而言,暴雨山洪灾害冲毁基础设施、对景区游客生命财产造成严重威胁,因此,山地景区暴雨山洪灾害的预警预报更为重要。利用DEM数据,结合美国SCS（Soil Conservation Service）模型,建立了分布式的山区中小流域山洪灾害模拟模型,并在长白山景区松江河流域进行验证。通过验证发现,本模型对山地景区的山洪灾害具有较好的模拟精度,可以为无水文资料的山地景区暴雨山洪灾害预警预报提供基础。

英文摘要：

the rainstorm and mountain flood disaster is one of the severe natural disasters that affect the small and medium river basin. Especially for mountain scenic area,mountain flood could destroy infrastructure and caused a serious threat to the lives and property of the tourist. Therefore,the flood early warning and forecasting for mountain scenic area is more important. Using DEM data,and combined with the SCS（ soil conservation service）model,this study established the distributed simulation model for mountain flood disaster in the small river basin,and validated it in the Songjiang River Basin of Changbai Mountain Scenic Area. The results show that the model has good simulation accuracy. The distributed simulation model can provide a basis for the early warning and forecasting of mountainous flood disaster in non-hydrological data areas.
