本文从成因、沟谷形态、物质成份,流体性质以及人类与泥石流活动关系等方面,划分天山阿拉沟泥石流为5组相应的类型组合。并对各泥石流类型特征及危害程度进行分析和评价。

About classification of debris flow, many scholars of China and abroad have done alarge number of works, and they put up various methods of classification and target.Thispaper consulted these results of classification,as well as the regional character of Alago ofTianShan Mountains, put up a series of classiying methods to be suiteble for this areas. In the classification of debris flow of the areas, The paper followed scicntifis principleand practical principle, reflected The nature of debris flow and the property and the harnessinformation of construction work. actting on the genesis of debris flow, the form of valley,the material composition, the fluid character,relationship between human being and debrisflow and so on, classified debris flow in to five related type. such as: rainstorm debris folw;valley debris flow and mountame slope debris flow and slope debris flow; rock grain flowand mud-rock flow and water-rock flow; viscous debris flow and microviscous flow andtransitiond debris flow; man made debris flow and natural debris flow. and the paper ana-lysis to the character and the harm degree of debris flow in the areas in orrder to utilize theresources of Tianshan Mountains reasonably and protect the natural environment of theTianshan Mountain and harnessing the debris flow in the Tianshan Mountains effectively.
