Pollen-based biome reconstruction at Middle Holocene (6 ka BP) and last glacial maximum (18 ka BP) in China
Biome (vegetation) reconstruction of the Middle Holocene ((6 000 +/- 500) a BP) and the Last Glacial Maximum ((18 000 +/- 2 000) a BP) in China was accomplished based on pollen data from "China Quternary Pollen data Base" and biomesation procedure. There are 116 pollen data used for 6 ka B...
