Pollen-based and Quantitative Reconstruction of Holocene Palaeovegetation of Surface Soil of Xinjiang

A total of 200 pollen samples of surface soil and 685 pollen records were used to reconstruct vegetation patterns in Xinjiang,based on a new global classification system of plant functional types(PFTs) and a standard numerical technique for biome assignment(Biomisation).The work processes include the establishment of pollen database,the design of plant function types,the design of biomes,reconstruction of modern vegetation and palaeovegetation patterns using the Biomisation method and the palaeovegetation mapping.It has got better uniformity between the reconstructed biome using the pollen sample of surface soil and the modern natural vegetation in the vertical distribution,and it is also ideal in the horizontal distribution.It proved this model can use in reconstructing the palaeobiome during the geologic history and can do some dynamic and quota analyses in Xinjiang.
