摘要
玛纳斯河发源于北天山中段 ,消失于准噶尔盆地西缘 ,是天山北麓流量最大的内流河。分析 195 4～ 2 0 0 1年红山嘴水文站的流量资料及 1986～ 2 0 0 1年的石河子市降水资料、温度资料 ,得出近 4 6年来玛纳斯河流量的变化规律 ;同时可以发现在一般情况下 ,玛纳斯河的降水与流量之间正相关 ,但在相对冷的年份 ,降水与流量的关系比较复杂 ,这是由于相对冷的年份 ,冰雪消融量减小 ,而抵消了降水引起的流量的增加 ;夏季温度的变化对玛纳斯河的流量影响作用较大。
The Manas river rises in the middle of the northern Tianshan Mountains and fades away in the west part of the Zungar Basin. Analyzing the stream discharges from 1954 to 2001 at the Hongshanzui stream gauging station, the precipitation and the temperature from 1986 to 2001 at Shihezi City, the rule of changing stream discharge in Manas river was concluded and it also can be found that the precipitation and the stream discharge have a positive relationship in common situation except in the cooler years. It is because that the decrease of the snow melt counteracts the increase of the runoff brought by precipitation in cooler years. The summer temperature change contributes more to the stream discharge of the Manas river.
