Sedimentological analyses of core sections of the Angulinao and Bojianghaizi Lakes show that the climates of these lakes have experienced several stages during the Megathermal of Holocene:warming during 8.4～7.3 ka BP, stable during 7.3～6.2 ka BP, fluctuation during 5.5～5.0 ka BP, sub stable humid during 5.0～3.0 ka BP and cooling down from 3.0 ka BP to present. The climatic changes in this region coincide with those in other regions of China. In 270 a BP, the climates turned to humid slightly, but since 1950 A.D., the climate becomes drying. Compared with sealevel fluctuation, the sediments in inland closed lakes have more advantages in studying climate change.
