     Moon Lake,in the middle part of the Daxing＇an Mountain Range,located at the current northern margin of the East Asian monsoon. Charcoal records of 886 - 546 cm sediment core of Moon Lake reveal the climate change from the Late Glacial to the early Holocene, which is effected by East Asian monsoon. The changes of charcoal concentration in the study area are mainly decided by the available burning biomass, forest steppe grown during warm period provide more available burning biomass. Low charcoal concentration presents under cold and humid climate conditions, while high charcoal concentration presents under warm and arid climate conditions in the same vegetation type. The result indicates relative low charcoal concentration stand for cold and dry climate conditions between 20.9 and 18.0 cal. ka B. P. ; the lowest charcoal concentration are typical of c01d and damp climate conditions present between 18.0 and 15.3 cal. ka B. P. ; the beginning of charcoal concentration increase marks the Late Glacial climatic amelioration towards warm from 15.3 to 14.4 cal. ka B. P. ; the dramatic changes of charcoal concentration from 14.4 to 11.8 cal. ka B. P. correlate with series of climate changes; overall the high charcoal concentration from 11.8 to 10.8 cal. ka B. P. occurred under warm and humid climate. The concentration of charcoal 〈50 μm indicates the evolution of regional fire history, the concentration of charcoal〉50 μm reflects the situation of local fire.
