摘要
随着人类活动对土地利用的范围不断扩大、强度不断加剧,不同的土地利用方式改变了土壤的理化性质、养分状况、土壤酶活性,进而对土壤肥力造成了不同程度的影响。文中从土壤微生物、养分状况、土壤酶活性和土壤的物理性质4个方面综述了土地利用变化对土壤肥力的影响。
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 direcdy 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.
