摘　　要：选取氨氮和高锰酸盐指数作为双指标,采用测次法对江苏省淮河流域2012年的水功能区达标情况进行了评价。结果表明,湖泊型水功能区达标率远高于河流型水功能区;地区之间达标率差异较大,徐州地区达标率较低。根据水功能区现状入河排污量和纳污能力,提出了规划水平年(2020年、2030年)纳污红线的限制排污总量分别为:2020年COD 4.35万t,氨氮0.43万t;2030年COD 3.20万t,氨氮0.25万t。NH3-N and(COD)Mnwere selected to evaluate the standard level of water function zones in the Huaihe River Basin of Jiangsu Province based on the time measuring method.The results showed that the standard-achievement rates of the lake water function zones are much higher than those of river water function zones,and the rates vary significantly in different regions with Xuzhou having the lowest rate.According to the volume of swage and water resources carrying capacity in the water function zones,the total allowable pollutants discharged in the planning years(2020and 2030)were estimated as 43.5thousand tons COD and 4.3thousand tons NH3-N in year 2020,and 32 thousand tons COD and 2.5thousand tons NH3-N in year 2030.
