Pollen-based past climate reconstruction for regions with long-term human occupation is always controversial. We examined the bias induced by the human impact on vegetation in a climate reconstruction for temperate eastern China by comparing the deviations in the reconstructed results for a fossil record (Lake Gonghai, 38.54°N, 112.14°E) based on two pollen-climate calibration sets. Climatic signals in pollen assemblages are indeed obscured by human impact; however, the extent of the bias could be assessed. The reconstructed anunal precipitation values of the last 14.7 kyr in the East Asian summer monsoon margin are given in the data set.
