Abstract

Non-point source pollution has been affecting the water quality of the Yellow River. Through the analysis of agricultural non-point source pollution,and its contribution to COD and NH3-N in Baiyin,it shows that the agricultural non-point source pollution has been the key factor to the pollution of Yellow river,only the load of COD in the farmland was 0.106 times as more as the whole and the load of NH3-N was 0.494 times in 2002.At last,some technology countermeasures against non-point source pollution were presented in this paper.
