| 摘 要： | 介绍了北京山区的泥石流灾害易发区的地质地貌特征、降水气候、泥石流类型及其空间分布特点。重点分析1950年以来，北京山区发生的11次严重泥石流灾害的降水特征，包括灾害发生前10d的降水过程、日降水量达200mm的地区与泥石流发生区、降水强度及泥石流爆发时间的关系等。并指出迎风坡或喇叭口地形，常是降水明显增幅、泥石流最易突发的区域。

| Abstract: | The characteristics of geology and rainfall climate for the mud-rock flow disaster region in Beijing mountain area,the type and space distribution of mud-rock flow is introduced. It’s stressed analysis that the rainfall characteristics for 11 severe mud-rock flow disasters, including rainfall intensity before 10 days of bursting disaster,the relationship of the rainfall region of surpassing 200 mm/d and the mud-rock flow region,the rainfall intensity and the bursting time of the mud-rock flow. It’s shown that the windward of mountain or the loudspeaker geography is the region of the rainfall increase obviously and the region bursting mud-rock flow easily. |
