摘要: 喀喇昆仑山巴托拉冰川水文的特征大部已在“巴托拉冰川融水径流的基本特征”,一文中进行了论述。本文仅就它未提及的和研究不够深入的某些水文特征进行探讨,作为上述论文的补充。

Abstract: This paper is a supplement to the previous one (see “Professional papers on the Batura Glacier,Karakoram” Mearta).In this paper we emphatically discussed the regularity of variation of runoff in time and space and the hydrological features of flood caused by glacial meltwater in the Batura River. We draw the following conclusions: (1)The Batura River is one of meltwater, which makes up about 75 per cent of its annual total discharge. (2)As a result of mutual supplement and adjustment between the discharge of the glacial ablation and the discharge of rainfall as well as, the adjusting effect of strong stagnant water in ice caverns,the annual range of discharge is comparatively small (Cv = 0.210). (3)As a result of the difference in thickness of supraglacial debris cover, the distribution of mean discharge depth in the drainage area is deeper in the middle rea-hes and shallower both in the upper and the lower reaches. At above 5,150m a.s.1., there is a zero value area of runoff(171 km2). (4)In summer if the fine days last longer and the temperature is higher,the discharge of peak flood will be bigger.
