滑坡泥石流由于具有突发性强、历时短、成灾快、破坏性强等特点，易造成巨大的财产损失，严重影响局部区域人民生命和生产安全，已经成为区域社会与生态环境可持续发展的重要制约因素之一。基于系统论理论及 DPSIR 模式，以全过程分析为主体设计思路，针对滑坡泥石流灾害特征，构建了一套包含监测站点、信息传输、评估预测、综合管理为一体的滑坡泥石流整体防御结构体系。

 Becaouse the landslide and debris flow are characterized by strong suddenness, short duration, quick disaster-causing and heavy damage, they would destroy various structures, such as houses, bridges, etc., damage farm land, hydraulic engineering facilities, and road engineerings, and thus, result in enormous property losses and injuries & deaths of the people-life, and influence regional sustainable development. So, on the basis of the systematic theory and DPSIR model, the paper takes whole process analysis as a primary thought, and according to the typical characteristics of the landslide and debris flow, analyses its defense system. By synthetic analysis of pressent achievements about this problem, an integrated defense system on the landslide and debris flow is brought forward.
