摘要
由于目前对群发性泥石流形成机理及成灾模式的研究甚少,加之在防范经验上的欠缺,难以找到有效的办法来降低这类泥石流造成的危害。为此,针对2010年群发性泥石流灾害频发事件,以近年来四川省典型群发性泥石流灾害为例,探讨这类泥石流灾害的空间分布特征及其灾害效应,并对群发性泥石流成灾的"叠加-放大效应"及成灾的"链式效应"进行分析,对认识群发性泥石流的成灾规律有一定理论意义。最后,就群发性泥石流灾害的防范及对策进行了探讨,可为防灾减灾提供参考。
The lack of research on group debris flow mechanism, disaster regulation and mitigation experience, it's difficulty to find effective way to reduce the damage of this debris flow. Focus on the high frequency of group debris flow in 2010, this article take typical debris flow occurred in Sichuan province in resent year as an example, discussed the space distribution characteristic and hazard effect of group debris flow, and analyzed the 'addition-enlargement effect' and 'chain effect', this can provide useful information for us to know the mechanism of this type of debris flow. Finally, this article give some suggestions for group debris flow prevention and mitigation.
