摘　　要：以佛山市为例,选取不同类型典型地块进行采样,计算不同类型地块农药和化肥的流失率。研究结果发现,不同类型地块农药和化肥的流失率是不同的。农药施用后,硫磷嗪在旱地上的流失率最高,敌敌畏在园林地上流失率最低,均小于1%;化肥施用后,N、P、NH3-N、COD在不同地块的流失率不同,N、P、COD流失率最大是草地,NH3-N流失率最大是旱地,结果基本符合实际,为有效控制农业面源污染提供依据。Agricultural non-point source pollutants were sampled and calculated typical plots in Foshan.The research results found that the loss rates of pesticides and fertilizers are different in different typical plots.After pesticide application,the loss rate of thiophazine on dry land was the highest,the loss rate of dichlorvos on garden land was the lowest,less than 1%.After fertilizer application,the loss rate of COD,NH3-N,TN and TP in different plots were different.The loss rate of N,P,COD on garden land was highest.The loss rate of NH3-N on dry land was highest.The results were basically in line with reality.The research results provided a basis for controlling agricultural non-point source pollution.
