Abstract:
The data of minidish evaporation in eastern Xinjiang from 1961 to 2001 and the meteorological factors which influence on the evaporation were analyzed. The re sult shows that evaporation is in decrease trend in eastern Xinjiang, increasing from 1970s to early 1980s and decreasing from middle 1980s to 2001 are abrupt c hange. The determinations of six kind of meteor ological factors to evaporation orderly are relative humidity, vapor pressure, t em perature, wind speed, sunshine hours, net earth surface radiation, the synerg ism of wind speed and sunshine hours, relative humidity and vapor pressure, tem perature and vapor pressure, temperature and relative humidity are also affects on the evaporation intensively. Relative humidity increases evidently in recent ly years, this is the main reason which leads to the evaporation reduction yearl y.
