Abstract:: Returning farmland to forest (grass) can effectively reduce the phosphorus loss of slope land, especially dissolved phosphorus.By the experiments of runoff plots without boundary, at the same precipitation, the particulate phosphorus content of runoff reduced 62.95% and 43.79% respectively and the PO₄^3--P content reduced 45.59% and 23.53% respectively after returning farmland to forest (grass); By the experiments of runoff plots in field, the dissolved phosphorus loss of runoff silt reduced 44.81% and 60.24% and the particulate phosphorus loss of runoff silt reduced 27.82% and 41.94% respectively.
