摘要
泥石流是一种危害严重的灾害形式。它的形成需要三个条件 :固体物质、水源和地形沟谷条件 ,而这些条件又受气候、地形地貌及地质等因素的影响。在不同地区有不同的主导因素 ,探讨了在中国西北干旱区影响泥石流发育的主导因素。通过分析得出 :在中国西北干旱区泥石流的主导影响因素是气候条件 ,特别是降水。
Debris Flow is one of serious disasters. There are three qualifications that are needed for its development: solid matter, water source and landform. Climate, landform and geological background are factors which influence these qualifications. The authors think that there is some different leading factor in different regions. The purpose is to try to discuss the leading factor which influence the development of debris flow in Northwestern China. The result shows that the leading factor is climate, especially precipitation.
