  1. Ecologic process of the wash lands by debris flows in mountain region is very complex and variety, and is a specific catastrophe - ecologic phenomenon in mountain region. plant growth of the wash lands of debris flow sdistributed in high altitude area shows a natural restorative proccss. it is found that plant growth process and community feature in the wash lands of debris flow can bring to light of the time of debris flow formation in the last hundred years and to the succession law of natural vegetation ecosystem through study in the catastrophc - ecologic phenomena and the ecologic process in wash lands of debris flow in the huangbenliu gully of the east slope of gongga mountain. the research result for this region also shows that study of the catastrophe - ecologic phenomena of debris flow can promote scientific infiltration between the ecology and the catastrophology, and has important theoretical and practical significances

    山區泥石流發生后的泥石流灘地呈現復雜多樣的生態過程，是山區所特有的一種災害生態現象.在人煙稀少的較高海拔，泥石流灘地植物生長表現為一種自然恢復過程.通過貢嘎山東坡高海拔黃崩溜溝泥石流灘地上發生的災害生態現象和過程的實地研究，發現泥石流灘地植物的生態過程和群落特徵，可以揭示近代泥石流的形成時間和自然植被生態系統的演替規律.研究表明，加強泥石災害生態現象的研究，可以促進災害學與生態學科的滲透，具有重要的理論和實踐意義
