Influence of habitats and terrains on soil nutrients of Seriphidum transiliense desert grassland

A field traditional survey was conducted to determine the effect of habitats and terrains on soil nutrients of Seriphidum transiliense desert grassland in the north slope of Tianshan Mountain for providing useful information for sustainable development of the animal husbandry and improvement of ecological environment. The results of this study showed that habitats and terrains greatly affected the soil chemical characteristics of S.transiliense desert grassland, and further affected the plant biomass. The available soil nutrients and organic matter in the vertical profile shared in a common from west habitat to east habitat as following: 0～10＞10～20＞20～30 cm layer; however, pH value showed a inversely trendy as following: 0～10＜10～20＜20～30 cm layer. This study also showed that habitats and terrains did not affect the vertical pattern of available soil nutrients in the soil profile.
