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 spring snow in the Qilian Mountains forest area is represented by the Pailougou watershed in the Xishui forest area of the Qilian Mountains. The results show that the snow distribution in the Qilian Mountains forest area has a great relationship with the altitude. The higher the elevation is, the more snow is accumulated. On the smaller scale The distribution of snow cover was related to the aspect, vegetation type and canopy density, which were mainly affected by forest vegetation. The snow cover formed a small snow-covered environment.
