摘要
春季融雪洪水是天山北坡积雪水文特征之一，有时形成灾害，造成一定财产损失和人员伤亡。本文根据天山北坡乌鲁木齐附近不同海拔四个气象台站冷季降水、蒸发、积雪和气温等资料，分析了春季融雪洪水规模及其产流的时空分布状况。
This paper is meant to analyze a size of spring snowmelt floods and temporal-spatial dis tribution conditions of their runoff formation based on the data of precipitation, evaporation,snowcover and air temperature from four meteorological stations with different elevations on the northern slope of Tianshan Mts.In general, the size of spring snowmelt floods is not so large, and the floods malnly oc cur in March and April. The main areas of runoff formation are in the middle and low moun tains. The spring runoff depth changes with elevation. The interannual change of spring snowmelt runoff is related to that of snowcover depth.
