Abstract:: Based on the natural rainfall data of the headwaters, the phosphorus losses of slope runoff were analyzed. The results showed that the phosphorus loss of slope runoff was consistent with runoff and soil erosion and the plantation has significant effects on control of phosphorus loss. In local traditional agricultural mode of flue-cured tobacco and corn planting, the significant phosphorus loss happened the 1～3 times in the rainfall period after fertilization. Changes in local agricultural structure, expansion of economic forest area, reduction of the impact of human activities on the ground surface are the keyes to solve the problem of phosphorus loss along with slope runoff.
