摘　　要：崩岗侵蚀是中国南方红壤区一种特殊的土壤侵蚀形式,其危害性极大。为了规划崩岗沙化洪积扇农业用地,提高农业经济效益,通过室外采样与室内分析的方法,研究安溪县洋坑小流域崩岗洪积扇不同土地利用方式的土壤性质差异。结果表明:不同土地利用方式下的土壤的理化性质均存在一定差异。以修正的内梅罗指数法对土壤肥力进行评价可知,水田、菜园、茶园和桉树林比肥力最低的撂荒地P值分别高150%、147.37%、105.26%、43.72%。通过试验研究得出,对崩岗沙化洪积扇农田区进行不同土地利用方式改良均能有效促进土壤熟化,其中,水田和菜园的效果较好。Collapsing erosion is a special form of soil erosion in China Southern Red Zone, the danger is great. In order to plan agricultural land use of sandy alluvial fan, improve economic efficiency in agriculture, the authors adopted outdoor and indoor sampling analysis to study differences of soil properties in Anxi County Gang Yang collapse pit alluvial fan of small watershed land use in different ways. The results showed that： the physical and chemical properties of soil under different land use patterns were different. Soil evaluation with the Nemerow index method showed that fertility of paddy fields, vegetable gardens, tea plantations and eucalyptus forests was higher than the P values of abandoned land for 150%, 147.37%, 105.26% and 43.72%, respectively. It is concluded that, the use of dilapidated granite sandy alluvial fan areas of farmland and gardens cultivated paddy soil could effectively promote ripening.
