Fire Dynamics in the central Great Khingan Mountains

To explain the relationship between fire activity and climate change in the East Asian summer monsoon (EASM) marginal zone, this study presents a microcharcoal record from Lake Tuofengling, providing a 25.0 kyr reconstruction of fire history in Northeast China. Firstly, microcharcoal particles were divided into large grains (50-200 μm) and small grains (10-50 μm) according to the long axes of each grain. Meanwhile, length to width ratio (L:W) of the microcharcoal particles was applied to distinguish sub-long (>2.5:1) from sub-round (<2.5:1) microcharcoals.
