| Abstract: | Land use is a general reflection of the human activities of using land and the most extensive,direct and profound influence factors to the soil fertility.With the intensity and amplification of land use,land use changes impacts the soil physicochemical properties,which directly impacted the soil fertility,nutrient status and soil enzyme activities.This paper reviewed the effect of land use changes on soil fertility following the changes of soil microbe,nutrient status,soil enzyme activities and soil physical properties. |

| Keywords: | land use changes soil enzyme activities soil organic matter soil fertility |
