中文摘要	通过对新疆赛里木湖流域现代植被调查及不同植被带的53个表土样品花粉鉴定分析,深入研究了该区域表土花粉组合与现代植被的关系。研究结果表明:表土花粉组合可反映出该流域植被的总体特征,赛里木湖流域不同植被带内花粉组合差异显著,依据花粉谱特征可以分为草原带、针叶林带、森林灌丛带、亚高山草甸带、荒漠草原带、草原灌丛带、荒漠植被带;云杉属、蒿属、藜科、禾本科含量高、变化明显,可作为该流域古环境重建的重要参考依据;蒿属/藜科(A/C)比值可以用来区分荒漠植被带和荒漠草原带,荒漠植被带A/C值平均为0.62,荒漠草原带A/C值平均为1.55,1是两者之间的界值;云杉属花粉含量≥30%时可认为该样品来自于云杉林,云杉属-蒿属-禾本科等花粉组合表明森林(灌丛)的存在,亚高山草甸以蒿属-禾本科-云杉属组合为主,(荒漠)草原(灌丛)以蒿属-藜科-禾本科为主,藜科-蒿属是荒漠植被的建群种。
英文摘要	In order to investigate the relationship between the surface pollen and modern vegetation,53 surface pollen samples from the Sayram lake,region northem Xinjiag,China were analyged.The result shows good correlation between the pollen assemblages of surface samples and the main vegetation types.Pollen assemblages have significant differences within different vegetation zones in the Sayram lake region.According to the pollen spectra,the surface samples were divided into steppe zone,Coniferous forest zone,forest-shrubs zone,subalpine meadow zone desert steppe zone,steppe-shrub zone and desert vegetation zone.The contents of Picea,Artemisia,Chenopodiaceae and Poaceae is high,and of obvious change,which can be used as an important reference for paleoenvironment reconstruction in the region.Ratio of Artemisiato Chenopodiaceae can be used to distinguish between the desert vegetation zone and the desert steppe zone,with a mean value of 0.62 in the desert vegetation zone and 1.55 in the desert steppe zone.If the percentage of piceais≥30%,it can be considered that the sample comes from the Piceaforest.Picea- Artemisia-Poaceae assemblage indicates the existence of forests(shrubs).The subalpine meadow is dominated by Artemisia- Poaceae-Piceaassemblage.(desert)steppe(shrub)is dominated by the Artemisia-Chenopodiaceae-Poaceae assemblage.Chenopodiaceae-Artemisiais the constructive species in desert vegetation.
