由于长江源区冰川变化幅度小，虽冰川退缩使冰川融水径流量有所增加，但对径流的影响程度相对较小。

Although retreat of glaciers causes increase in glacier melt water runoff, the effect of glacier retreat on sur - face runoff is relatively small because of small amplitude of glacier change.

入渗是水文循环过程中一个重要环节，在长江源区，土壤水分入渗对径流的影响很大，也是高原生态系统重要的影响因素。

Infiltration is an important process in hydrologic cycle, in the source region of Yangtze River, infiltration of soil moisture has impact in runoff and plateau ecology.
