The 42 lakes compiled in the Chinese Lake Status Data Base (CLSDB), has provided the information of the spatial changes of lake status for each one-thousand year, which can be purposed for research on the atmospheric circulation changes of Chinese region since LGM, The results have shown that, the relatively wet conditions of western China from LGM to Mid-Holocene was probably related to the precipitation brought by the westlies and the low evaporation in Glacial period, and summer monsoon precipitation in Holocene.And the climate turned drier since late-Holocene.Most area in eastern China during LGM and late-Glacial was relatively dry, and turned wetter in Holocene.The summer monsoon precipitation during Mid-Holocene might reach the whole western China.In eastern China, there exists the diachronity for the maximum effective precipitation from north to south during Holocene,occurring during late-Holocene in southern china.The wet condition of southwestern China occurred clearly in late-Glacial, which is earlier than in southeastern China, suggesting that a balance occurred between these two monsoon systems.The earlier oc-currenceof wet conditions in northeastern China suggests an independent monsoon systems in this area.
