摘要
The global change research needs to describe the past vegetation condition of Earth system. This paper chose Xinjiang as the study area to reconstruct 14 time intervals biomes, based on a global classification system of plant functional types (PFTs), a numerical technique for biome assignment (biomisation) and a total of 600 fossil pollen records. All fossil pollen records in Xinjiang during the Holocene were collected and statistically analyzed, including pollen types, pollen grain percentage, radiacarbon dating and geographic coordinates. Some of the pollen records were digitized from published pollen diagrams using the Digitizer software.
