Abstract:Judging from the analysis of lakeshure-geomopho1ogy and referring to the paleoelimate of selected section.in the past l 0000 years, Ebinur Lake experienced thfee stages of high lake-level:6.5ka- 8.0ka B.P..4.5ka-6.0ka B.P.and 2.0ka-3.Oka B.P..higher than that of present by 25m , 17m and.Responsively, their surfae areas were 3000 km2 , 2330 km2 and 1334 km2 respectively.In this paper, in terms of a hydroingica l an d energy-balarlce med e1.the sensitivity of its param eters js discussed in detail, an d also, paleopre, cipitation of three high lake—level stages estim ated. Among these param eters lake c(Jefficient is the main factor affecthag the estim ation of paleoprecipitation.And lan d albedo, Bowen ratio and cloud cover also show high sensitive—But tem peratnre indicates relatively low sensitivity- By applying this hydrological an d energy’balan ce model, the estim ates of paleopreeipitation in different pe riods are obtained.In proper order, the average precipitation was:332 mm /a in 6.5 ka- 8, 0 ka B. P., an increase by 22 of the present;305 mm/a in 4.5 ka- 6.0 ka B.P., an incre&se by l6 and 287mm/a in 2.0-3.0 ka B.P., an increase by 9 of the present.
