Abstract:: For meeting the needs of the water resources protection and the water pollution control planning,this paper makes the analysis of relationship between runoff and pollution load of Tumenxigou outlet.Main results are as follows: the content of Nitrogen and Phosphorus exceed standard,especially nitrogen content is much more than class Ⅴ,Phosphorus content is less than Class Ⅲ,Nitrogen and Phosphorus is the main pollution.The runoff have a good relationship with pollution load,correlation coefficient between runoff and phosphorus is most well.The Nitrogen has the bad relation with runoff.Ammonia and Nitrogen are the main existent feature in nitrogen sources pollution,which has relation with the local nitrogenous fertilizer and diammonium.Nitrogen has good relation with Ammonia and Nitrogen,bad relation with nitrate nitrogen.Pollution emission controlling and rainstorm surface runoff decreasing are the effective measures.
