Effects of biological soil crust on slope soil carbon and nitrogen under erosion conditions
侵蚀条件下生物结皮对坡面土壤碳氮的影响

In order to reveal the effects of biological soil crust(BSC) on the distribution of soil carbon and nitrogen on slope under erosion conditions,by experimenting on field plots and in laboratory,this study investigated the distribution pattern of soil organic matter,total nitrogen and nitrate nitrogen contents with BSC treatment and without crust group.The results indicated that: biological soil crust played significant role in soil carbon and nitrogen accumulation.In the same position on slope,soil organic m...
