The " Grain for Green冶 project is essential for controlling soil erosion in the Gully Region of the Loess Plateau, which has one of the most serious water and soil loss problems in the world. Different vegetation types change the soil environment to different extents, influencing the biogeochemical cycles of materials, such as nitrogen ( N) . At present, a growing number of researchers are investigating the relationship between vegetation and N forms in natural ecological systems to provide a theoretical basis for ecological restoration in these areas. In this paper, the effect of vegetation types on the concentration and transformation of various soil N types ( soil total N, organic N, N mineralizable within 14 d, microbial biomass N, nitrate N and ammonium N) in the Dongzigou Basin, Ansai, Shaanxi Province was investigated. Soil samples were collected from the 0-10 and 10-20 cm layers under eight typical vegetation types, including Quercus liaotungensis, Acer buergerianum Miq, Platycladus orientalis, Robinia pseudoacacia, Syzygium aromaticum, Sophora davidii, Artemisia
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
