Abstract

Soil erosion is serious in the Loess Plateau and soil organic carbon (SOC)in this area is lower than the average in China .SOC is a large component of the global carbon cycle and an important index to evaluate soil quality .In order to understand impact of vegetation on SOC at slope of Wangdonggou Watershed in Gully Region of Loess Plateau , SOC level and distribution characteristic along a slope under vegetation types were investigated . Through comparing the concentration of SOC and its distribution in soil profiles under crop land , orchard , forest land , grass land and clover land , the results demonstrated that compared with crop land , SOC content increased by 25.3 %, 17.1 % and 11.6 % for forest land , grass land , clover land and decreased by 2.2 % for orchard .The SOC content and the distribution in soil profile would change with the change of land use typs in slope land in gully region of Loess Plateau .In addition , there was a significantly correlation between TSN and SOC .[ Ch , 1 fig .3 tab .16 ref .]
