| 摘 要： | 以多年河流统计监测资料为基础,运用两点法,考虑非点源影响,逆推计算,求得地表水非点源污染负荷。以吉林省为例,分析了吉林省4大水系15条河流65个监测断面2000~2004年统计资料,运用两点法确定吉林省主要河流COD衰减系数(K),逆推计算得到吉林省非点源污染负荷为1443.711m3/s,其中松花江水系802.93m3/s,图们江水系108.369m3/s,辽河水系372.392m3/s,浑江、鸭绿江水系160.02m3/s。非点源污染负荷是点源污染负荷的57.14倍,成为吉林省地表水环境主要污染源。

| Abstract: | The non-point source pollution loads(NPSPL) were derived from the converse inference and adjusting by the two-point method on the basis of the statistic and monitored data.In the case of Jilin province,the total loads were 1 443.711 m(3)/s,of which,the Songhua River systems were 802.93 m(3)/s,Tumen river systems were 108.369m(3)/s,Liaohe river systems were 372.392m(3)/s,Yalv river and Hunjiang river systems were 160.02 m(3)/s,on the basis of the main rivers delay coefficients,by analyzing the statistic and monitored data of the main 15 rivers in Jilin Province from 2000 to 2004.The NPSPL is as 57.14 times as the point sowne loads,and has been the main factor of the surface water. |
