Fire Dynamics in the central Great Khingan Mountains

Description

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.
