利用一种新的全球植物功能型分类系统(PFTs)和标准的孢粉生物群区化定量技术(Biomisation),共36个表土孢粉采样点(200个表土孢粉样品)参与重建新疆植被的模拟。包括建立孢粉数据库、设计植物功能型、设计生物群区、利用Biomisation方法重建表土植被和古植被以及制图等主要内容。利用表土孢粉样品在垂直海拔上重建的生物群区与现代自然植被表现出较好的一致性,在水平地带分布上也获得理想结果,证明该模型可用于重建新疆过去地质历史时期古生物群区,并进行动态定量分析。
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.
