Regulative effect of Qilian Mountain on climate in Huangshui River basin

Glaciers have the service value of climate regulation, runoff regulation, fresh water supply and tourism research. Can be embodied in the form of money. The size of glacier area directly affects the service value of glaciers. The modern glaciers in Qilian Mountain area are very large, which generally develop above 4000 meters above sea level. The area of Liucheng glacier in Shule River is more than twice that of Beida River City. The research shows that the climate regulation value of glaciers is much higher than other services; With the global warming, the glaciers in Qilian Mountain area have obviously subsided, and there are great regional differences. Regardless of the price factor, in recent years, the decline of glacier service value in eastern Qilian Mountain is greater than that in western Qilian Mountain.

The regulating effect of Qilian Mountain glaciers on local climate: glaciers reflect solar radiation, reduce ground radiation, melt glaciers to absorb heat, reduce temperature and alleviate climate warming.
