Abstract Total of 55 topsoil pollen samples from Shiyang river drainange, a typical small drainage in arid area of Northwest China, have been analyzed. The result shows that two types of pollen assemblages can be distinguished from the topsoil pollen assemblages. Above the steppe desert vegetation zone, the pollen assemblages are dominated by Picea pollen, and cannot reflect the nature of local vegetation except in forest zone. The percentage of conifer pollen is high about 80% even in alpine cushion-like vegetation zone, and is still high at 20% within 50 km away from forest. Below the steppe desert vegetation zone, the pollen assemblages are dominated by shrub and herb pollen, reflecting local vegetation generally. Stronger wind transport causes the pollen assemblage presenting such charactristc. Vegetation is better presented by absolute concentration, namely the absolute concentration of pollen decreases largely after pollen leaves the matrix plants. The percentage pollen assemblages of surface samples are influenced by the distribution of vegetation and the climate condition in research area. Therefore, the corresponding relationship between the percentage of pollen spectra and vegetation is not good, most shrub and herb pollen can reflect vegetation basically, but tree pollen can not present the distribution of forest.
