In order to clarify the agricultural non-point source pollution in Wuling Mountain Area, the total nitrogen (TN) and total phosphorus (TP) pollution loads from agricultural nonpoint source pollution in Jishou city in 2018 were estimated and assessed according to the output coefficient method and the equivalent pollution load method. The results show that the TN and TP pollution loads of agricultural non-point source pollution in Jishou City are 992.698 and 82.887 t, respectively, and the corresponding equivalent pollution loads are 9.927×108 and 4.148×108 m3. The greatest contribution rate of pollution sources to TN and TP loads comes from agricultural fertilizer, followed by rural life and livestock and poultry farming.The research puts forward  suggestions and countermeasures for the agricultural non-point source pollution in Jishou City.

Key words: Wuling Mountain Area, agricultural non-point source pollution, output coefficient method, equal standard pollution load method, control strategy
