摘　　要：安徽省长防林工程区约有２ 万ｈｍ２ 坡耕地，是水土流失最严重，也是治理难度最大的地类。在可持续发展理论的指导下，经过近１０ 年的探索，根据混农造林的时空结构，研究推广了几种适合于工程区发展的混农造林模式。混农造林以其投入低、效益高、见效快，已经成为长防林工程区２５°以下坡耕地改造的主要方式。In Anhui Changjiang River conservation forest project area there is 20000 hm 2 sloping cultivated land where the soil and water loss is serious and the goveming is the most difficult.Under the guidance of sustainable development theory,through exploring for 10 years according to time space framework,several kinds of agroforestry models which are suitable for project area have been studied and developed.Agroforestry is the most efficient method to control soil and water loss on sloping cultivated land where gradient is bellow 25°.
