采用生态足迹分析的方法估算了赣江中游万安水库上游阳坑小流域水土保持生态承载力，分析了小流域水土保持的综合效益。研究表明，阳坑小流域水土保持措施总计增加生态承载力2154.5 hm2，其中约80%为水土保持措施直接的增产作用，主要集中在小流域当地；土壤固碳和涵养水源的作用各自占总生态承载力的10%左右，这部分效益对赣江流域甚至更大的区域都有影响；水土保持综合效益主要集中在小流域当地。

The ecological capacity in soil and water conservation at Yangkeng Watershed,which is located at the upper reaches of Wan’an Reservoir and the middle reaches of Ganjiang,is estimated with the meth-od of ecological footprint analysis,and the comprehensive benefits of soil and water conservation at Yangkeng Watershed is analyzed. The research indicates that the soil and water conservation measures taken at Yangkeng Watershed help to increase the ecological capacity as much as 2 154. 5 hm2 ,80% of which was brought about through the soil and water conservation measures;that the carbon capture func-tion of soil and water conservation function reaches 10% respectively,which is influential to the whole Ganjiang Watershed or a even larger area;and that the comprehensive benefits of soil and water conserva-tion remain largely at the local watershed.
