| 摘 要： | 采用样方调查和演替层次法对林芝县芽依泥石流沉积区植物群落物种组成和演替特征进行研究，结果表明：芽依泥石流发生年限100年左右。该区群落植物种类丰富，主要植物共11种；群落组成为川滇高山栎＋云南锦鸡儿＋西南草莓，优势先锋种糙皮桦开始淘汰。植物群落演替阶段基本进入衰退阶段。

| Abstract: | The species composition and succession characteristics of plant community in Yayi debris flow deposition were studied by quadrat survey and succession level methods. The results showed that, Yayi debris flow occurred around 100 a. The comnmnity species was richness and there were 11 main plants in debris flow depositional area. The conmmnity composition was Quercus aquifolioides ＋ Caraganafrartchetiava ＋ Fragaria moupinensis, and the pioneer species of Betula utilis had fallen into disuse. The succession of plant community stepped into the stage of recession. |
