Abstract:
The objectives are to understand the laws how soil microbial biomass carbon and soil nutrients respond to different land use patterns，and thus to provide a basis for eco-construction in the agro-pasture zigzag zone in Inner Mongolia.Three land use patterns were studied，including natural grassland，sloping cropland converted from natural grassland，and 22-year-old Populus simonii man-made forest.The changing laws of both soil microbial biomass carbon and soil nutrients were studied.The results showed that land use patterns significantly affected the soil microbial biomass carbon contents and the effects were significantly different among land use patterns，22-year-old P.simonii forest>natural grassland>sloping cropland.As for the vertical distribution，soil microbial biomass carbon contents declined with the increase of soil depth for each land use pattern.Soil microbial biomass carbon content was significantly correlated with available K(AK) content，total N(TN) content，pH and bulk density，indicating soil microbial biomass carbon could be used as a sensitive indicator to measure the changes of soil quality.
