通过对滇东北山区坡耕地５种主要水土保持措施———等高带状耕作、地埂、生物防冲带－绿肥、生物防冲带－苹果、水平梯地（梯田）对土壤流失量的控制作用建立试验小区并进行连续３年实测，得到各种水土保持措施的Ｐ值，为建立坡耕地水土流失方程、进行土壤侵蚀预测预报、制定坡耕地水土保持措施奠定了可靠的基础。
Through five kinds of soil and water conservation measures of sloping farmland in the northeastern Yunnan, such as contour strip farming, Dioscorea zingiberensis, bio-anti-red belt-green manure, bio-anti-punching belt-apple and terraced fields Control and establish pilot area for 3 consecutive years. The P value of various soil and water conservation measures was obtained, which laid a solid foundation for establishing soil erosion equation and predicting soil erosion and developing soil and water conservation measures for sloping fields.
