山区泥石流发生后的泥石流滩地呈现复杂多样的生态过程，是山区所特有的一种灾害生态现象。在人烟稀少的较高海拔，泥石流滩地植物生长表现为一种自然恢复过程。通过贡嘎山东坡高海拔黄崩溜沟泥石流滩地上发生的灾害生态现象和过程的实地研究，发现泥石流滩地植物的生态过程和群落特征，可以揭示近代泥石流的形成时间和自然植被生态系统的演替规律。研究表明，加强泥石灾害生态现象的研究，可以促进灾害学与生态学科的渗透，具有重要的理理论实践意义。
The debris flow beach after the occurrence of debris flow in the mountain area presents a complex and diverse ecological process and is a kind of disaster ecology phenomenon peculiar to the mountainous area. Plant growth at a sparsely populated, high-altitude, debris-flow beach is a natural recovery process. Through the field research on the disaster ecological phenomenon and process in the debris flow beach of Huangbingougou at the east slope of Gongga Mountain, it is found that the ecological process and community characteristics of debris flow beach plant can reveal the formation time of modern debris flow and the performance of natural vegetation ecosystem For the law. The research shows that strengthening the researches on ecological phenomena of debris disasters can promote the infiltration of disaster science and ecology, which has important theoretical and practical significance.
