Abstract Plant root activity plays important role in material turnover in plant-soil systems. In order to investigate the distribution of Artemisia halodendron's root, vegetation character, live root and necromass (dead root and cell sloughing of epidermal root tissues) during the growing season were investigated in 4 different positions (bottom, mid-slope, top and leeward) of dunes in the Horqin Sandy Land. The result showed that: Both live root mass and necromass were significantly different among slop positions in semi-fixed dune. In terms of live root mass distribution, there were different characters in these 4 positions, most of the live-root biomass was allocated at the depth of 0-20 cm in middle-slope and top of the dune, while in bottom and leeward, the variations were slight. Vertical distribution of the total mass and necromass all significantly declined among soil depth in all the 4 positions. Meanwhile, ecological index of plant community and growth character of A. halodendron among slop positions showed significantly difference: coverage and richness in bottom were significantly higher than others, and both in bottom and leeward, density of A. halodendron decreased while its height increased. Live root mass of A. halodendron played significant relationship positively with its density while negatively with its height (p<0.05). In conclusion, allocation and growth character of A. halodendron showed an important reflection of growing strategy variation among habitats in sand land.
