摘要
北京山区泥石流灾害较为发育。泥石流灾害受控于多种因子,在详尽分析了地形地貌、地质条件以及降雨分布等影响因素的基础上,通过应用GIS强大的空间分析和处理功能,深入研究构建泥石流灾害发生概率评价的多元信息复合叠加模型,并对泥石流发生概率的评价方法进行初步探讨。
There are many debris flow disaster in Beijing mountainous area.The debris flow disaster controlled by a variety of factors.Based on detailed analysis of the influencing factors such as the topography,geological conditions and rainfall distribution,the paper studies how to construct the superposition model of multi-information predicting probability of debris flow disaster by applying powerful spatial analysis and processing functions of GIS,and discusses the evaluation method on the occurrence probability of debris flow disaster.
