Fire history can be obtained from the charcoal record on the southwest plateau of Guizhou

Fire has a nonlinear relationship with climate and vegetation. Therefore,identifying the mode and mechanisms of fire in the East Asian monsoon area is very important when attempting to predict future climate change and improve fire management. A 110 cm continuous core from the southwest plateau of Guizhou was sampled at 1 cm intervals for charcoal analysis. The chronology of the core extended from MIS3 to MIS2. The results show that since the late MIS3,fire mainly happened in the 36.3-35 cal ka BP and 26.2-17.6 cal ka BP periods. Three local fires happened in the 35 cal ka BP,26.2 cal ka BP,and 23.6 cal ka BP periods,and these were identified from the large and medium size charcoal particles.Comparison of the charcoal record with stalagmite and ice core records indicated that the peak in the charcoal record corresponds to cold-dry events,such as Heinrich and Last Glacial Maximun(LGM),and the low value area corresponds to DO events. These results have Millennium oscillation characteristics. A comparison with o
