| 摘 要： | 在分析研究泥石流灾害特征的基础上,指出海子沟泥石流的爆发主要受到松散堆积物、坡度、降水、地质、植被等因素影响.据此,建立起泥石流爆发危险性评价数据库、知识库和危险性评价数字环境模型.在ArcGIS的支持下对所选取因子进行详细分析,得到海子沟流域泥石流危险性评价图,为海子沟流域泥石流防治工程提供了重要的依据.

| Abstract: | Haizi valley of Yunnan province is an area where debris flow takes place frequently.In the paper,through analyzing the characteristics of the debris flow in Haizi valley,it has been pointed out that the breaking out of the debris flow is related to unconsolidated deposit,gradient, precipitation,geology,and vegetation.On the base of the database,repository and the digital environmental model for assessing the risk of debris flow disasters were built.By the supporting of ArcGIS,the map of risk assessment of debris flow in Haizi valley was obtained.The analyzed results offer an essential reference to control the debris flow in Haizi valley. |
