摘要
本文对天山山区积雪分布的分析表明:山区积雪消融过程和积雪水量的分布是有一定规律的,积雪深随高度的增加可近似用线性函数表示.在积雪期任一高度的累积积雪深与同一坡面上所选任一高度为基点的累积积雪深成比例.积雪比例系数随高度而变化。上述积雪分布规律是在积雪没有受扰动的自然情况下成立,在高山带,由风吹雪所形成的积雪再分配变得更加复杂.
In this paper,snowpack distribution for Tian Shan mountain is analysed.This result indicated that the process of snowfall and snowmelt for mountain region and distribution for water equivalent of snowpack has some regularity. A increasing of snowpack depth with alititude can expresses appeoximately by a
linear function In the term of snowpack,at any altitude the cumulative depth
of snowpack have ratio to cumulative snowpack depth at the same hillslope of
any altitude which is selected for reference point.Above stated that snowpack
distributive regularity exists only for natural condition of snowpack without tur
bulent In an alpine zone because snowpack redistribution formed by windswep,
it become-very complex.
