Research on interannual variation characteristics of non-point source pollution on control section of Fenghe River
摘要
Abstract
In order to research the interannual variation characteristics of non-point source pollution on control section of Fenghe river,the paper took Fenghe river which is tributary of Weihe river as a exam-ple, based on 1992-2011 long-term synchronous and 2009 -2011 non-point source pollution synchro-nous monitoring water quality and flow data of Qinduzhen section in Fenghe River, and used the mean concentration method to calculate the point source and non-point source concentration, total pollution load, the load proportion of non-point source pollution of NH3—N from 1992 to 2011,and COD, TP and TN from 2003 to 2011,and fitted the correlativity between the load proportion of non-point source, total pollution load and comprehensive pollution index, and analyzed the variation characteristics of non-point source pollution. The results show that non-point source pollution load proportion of NH3—N and TN are more remarkably affected by surface runoff and total pollution load than other factors;the interannual vari-ation tendency of river total pollution load is similar to the tendency of basin surface runoff;the non-point source load proportion of nitrogen pollution presents declining trend in interannual variation, and the non-point source load proportion of COD and TP is on the rise.关键词
