On the basis of soil sporopollen assemblages and so me climate indexes, a transfer function of pollenclimate in shennongjia mountains is established by mcans of a statistical method. Based on the function, pale oclimate of late Quatereary is analyzed in Dajiuhu lake area. The end of Pleistocene (10 600～12 500 a.B.P) is still in ice age and the climate is cold and dry. Annual mean Temperature (AMT) and annual mean precipitation (AMP) at that time are about 8℃ and 150～200 mm, lower than that at present. Early Holocene (7 400～10 600 a.B.P) is a climate transit stage, mwhich both AMT and AMP increase quickly. Middle Holocene (4 000～7 400 a.B.P) is the warmest and humidest in late Quarternary and AMT and AMT are about 3.5℃ and 300 mm higher than that at pres ent respectively. Late Holocene (4 000 a.B.P) is warm and wet and AMT and AMP fluctuate at a small scale.
