| Abstract: | Soil seed bank of natural vegetation in desert-oasis ecotone were investigated in Kawake township of Moyu county in Xinjiang.Distribution,reserves & diversity of seed bank were analyzed.Result shows that: within the study area,active seed of the soil is much lower from the point of view of total reserves;with the farther away from the bank,soil seed bank reserve decrease more quickly.Investigation shows that: the study area have total of 10 species of plants belonging to 6 families,but the distribution of n... |
