摘要： 本文给出了1986-1987年冬春两季积雪辐射平衡的数据以及积雪辐射平衡与短波辐射平衡、长波辐射平衡的同步变化关系;指出了短波辐射平衡对融雪的积极作用,强调了积雪反射率对融雪过程的负反馈机制;并将积雪辐射平衡与融土辐射平衡进行了类比;从能量平衡的观点对不同容重的积雪融化速率进行了分析.该文的结果对研究积雪融化具有重要意义。

Abstract:

This paper is the furture results of the literature〔1〕.The figures authors given the and the data of net radiation of snowcover during the winter-spring 1986-1987.The relationship between shortwave radiation equilibrium in thawing process of snow has the activity.We emphasised that Smowcover's albedo during the snow thawing process have the negative feedback mechnism as follows：

Here, R is the snowcover's albedo, W is snow water content, Qnet is the longwave radiation equilibium of snowcover, [(S+H)-R] is the shortwave radiation equilibrium of snowcover.
Form energy equilibrium point of view, analysics the thawwing rrate of smowcover thawing process invarious snowcover, density.The results are of imortant significance of thawwing snowcover hydrology.
