摘要：
The formation process of the non-point source pollution (NSP) was understood, through research and survey of Ashi River Basin of China. Different sources of NSP loads were obtained, by different sources of NSP monitoring techniques and estimation methods. The amount of NSP into the river was obtained, by monitoring techniques and estimation methods of NSP into the river in the Basin. The monitoring technology and loading estimation method system of NSP in the Ashi River Basin was established. It were calculated that different sources of NSP loading of total nitrogen (TN) was 8975.42t and total phosphorus (TP) was 606.27 t in 2010. NSP coefficient into the river the amount of TN was 4140.75 t and TP was 343.98 t, therefore, TN was 0.46, TP was 0.57 of the NSP into the river coefficient in the Ashi River Basin in 2010.
