Abstract: 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.
