%X An investigation was made on the species composition and eco-type of Hemiptelea davidii community on Kerqin sandy land.The results showed that in study area,no shrub layer existed in H.davidii forest,while arbor layer could be divided into two sub-layers,with a height of 4.05-7.86 m for the upper layer,and of 2.05-3.20 m for the lower layer.In the community,there were 32 herbal species belonging to 27 genera of 13 families and dominant by Poaceae,Fabaceae and Compositae,and 11 areal types,among which,the species number in Mongolian-Northeastern China-Dahuricia-North China areal type was the highest(34.38%),followed by that in Northeastern China-North China areal type(12.5%).Among three water ecological types,mesophytes occupied 59.37% of the total,and mesoxerophytes and xerophytes occupied 25% and 15.63%,respectively.Hemicryptophytes had a larger amount in six life forms,accounting for 31.25% of the total.H.davidii community had the typical life form characteristics of temperate steppe.
