| 摘 要： | 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。

| Abstract: | By means of setting up experimental spots of the controlling effect of five main soil conservation measures (i.e. contour strip cropping,building ridge,biological wash_resistant belt green manure crop belt and apple belt,and contour terraced field) on soil loss amount of sloping cultivated land in the northeast mountain region of Yunnan province,and measuring continuously over three years,the P values of every measures has been drew out,i.e. contour strip cropping 0 5532,building ridge 0 1836,biological wash_resistant belt green manure crop belt 0 3745,apple belt 0 4962,contour terraced field 0 0316.The results showed that carrying out the engineering of transforming slope into terrace is the root measure of controlling soil erosion of sloping cultivated land. |
