Abstract:: For detailed elucidation of the typical mechanism of phosphorus with runoff in a small watershed of orchard when rainfall occurs,and supplying enough scientific foundations to decrease the application rates of fertilizers,this study was carried out from July to August in 2009 for consecutive investigation of runoff processes,and simultaneously monitoring the non-point output process and loads of total phosphorus (TP),phosphate and particle-phosphorus (PP),in Xinchang Town,where was a typical municipal farming zone of Nanhui District in Shanghai.The results indicated that the change trends of runoffs and rainfalls were approximately consistent in three storming processes.Meanwhile the concentrations of TP and PP changed with the varieties of runoff,and especially an increasing trend was observed significantly when runoff increased,after that,it stabilized without varieties.The greatest values of phosphorus losses all appeared before the occurrence of runoff peak values.In the three storming events,the average values of PP losses were 6.38mg/L,7.65mg/L,4.12mg/L,respectively,with the average values of TP were 7.88mg/L,8.92mg/L and 5.36mg/L,respectively,which accounted for 76.9%~85.5% of TP losses,thus the amount of PP losses was higher than dissolved phosphorus losses.In addition,the effect of rainfall intensity (RI) on phosphorus losses load was significant,which showed the TP loss load was 10⁸kg/hm² accounting for 65.69% of TP losses,when RI was the greatest (149.5mm).
