中文摘要：

Jiangjia 沟壑是在 Dongchuan 的一条闻名全球的碎片流动山谷，云南省，中国。大量山崩和倒塌发生了并且引起了庞大的损坏到民族性质和生活的每年。与长期的观察并且在我们发现了的 Jiangjia 沟壑测试有山崩和倒塌的特征的一个种特殊山崩。山崩和倒塌为碎片流动供应了足够的材料。当碎片流动爆发了时，某种共生交互生长在降雨，山崩和碎片流动之中存在。为了学习共生交互生长和一些，给参数调音，我们执行了人工的降雨山崩测试和模型实验观察象倒塌，表面幻灯片和表面流动那样的现象。由观察试验性的现象并且监视水内容，在在降雨的条件下面的山崩存款和碎片流动之中的转变过程被分析了。研究结果在 Jiangjia 沟壑在降雨，山崩和碎片流动之中揭示了这种共生交互生长的关系。同时，仅仅当潮湿内容在某个范围时，这种共生交互生长关系存在，这被发现仅仅当潮湿内容在某个范围时。也就是说，批评状态似乎在转变过程被存在。

英文摘要：

Jiangjia Ravine is a world-famous debris flow valley in Dongchuan,Yunnan Province,China.Every year large numbers of landslides and collapses happened and caused enormous damages to people＇s properties and lives.With longtime observation and testing in Jiangjia Ravine we had found out one kind of special landslide which had the characteristics of landslide and collapse.Landslide and collapse supplied sufficient materials for debris flow.When a debris flow broke out,some kind of intergrowth existed among rainfall,landslide and debris flow.In order to study the intergrowth and some key parameters,we carried out artificial rainfall landslide tests and model experiments to observe the phenomena such as collapse,surface slide and surface flow.By observing the experimental phenomena and monitoring water contents,the transformation process among landslide deposits and debris flow under the condition of rainfall had been analyzed.Research results revealed the relationship of this kind of intergrowth among rainfall,landslide and debris flow in Jiangjia Ravine.Meanwhile,it was found that this kind of intergrowth relationship existed only when the moisture content was in a certain range.That is,the critical state seemed to be existed in the transformation process.
