Abstract:
Nitrogen and phosphorus losses mechanisms from agro-forestry system was investigated in a rainfall simulation experiment with a constant rainfall rate of 1.43 mm /min. The results showed that agro-forestry systems can drop amounts of total nitrogen(54.9%-89.1%)and total phosphorus(68.6%-88.9%)carried away by runoff. Agro-forestry systems can reduce water runoff(56.7%-70.6%)and sediment(52.1%-61.5%). In agro-forestry system, the concentration of TN and DN is rapid decline, then rise. At the beginning of runoff, NO-3-N is stable, then close to be increase; NH+4-N, TP and PP have the same regular pattern. Their concentration is high in the initial time, tends to be decreased with rainfall continuing.
