ABSTRACT
The loss regularity of nitrogen (N), phosphorus (P), and chemical oxygen demand (CODMn) of runoff under different rainfall intensity and different management practices in Phyllostachys praecox cv. prevernalis forest land was studied. The total nitrogen (TN) and CODMn concentration in runoff were significantly correlated with the rainfall intensity under the three management modes named as control, fertilization, and cover. Moreover, N mainly lost in the form of nitrate (NO3--N). Generally, the relationship between total and dissolved phosphorus (TP and DP) loss in the three management modes was estimated in following orders coverage > fertilization > control. The loss of P was mainly in the granular state, and the loss of DP only accounted negligible amount of the TP loss. The loss of CODMn was closely related to the magnitude of rainfall intensity. Results revealed that CODMn concentration in runoff under fertilization and cover management was significantly correlated with the rain fall intensity.
