摘　　要：以祁连山西水林区排露沟流域为代表研究祁连山林区春天积雪分布规律 ,表明祁连山林区积雪分布与海拔高度关系极大 ,海拔越高 ,积雪越多 ;在较小尺度上 ,积雪分布与坡向、植被类型、林分郁闭度等因子有关 ,主要受森林植被影响 ,森林植被形成积雪小环境。The distribution of snowpack in spring is studied with Pailugou catchments of Qilian Mountains forest area as the subject. The conclusions are as follows: the distribution of snowpack is closely connected with altitude, the higher of the altitude, the thicker of the snowpack. In a small scale, the distribution is related to exposure, vegetation type, crown density, etc.
