【摘要】 为了解丹河近几年水环境质量状况及发展演变趋势,根据丹河2004—2008年6个断面的水质监测资料,选取影响丹河水质的主要污染因子COD,BOD5,NH3-N及石油类,运用模糊综合评价法对其水质现状进行评价,并采用综合污染指数法和Spearman秩相关系数法分析了水质演变趋势.结果表明:丹河水体污染严重,属Ⅴ类水,尤其是高平河西和水东桥两个断面,水环境保护工作刻不容缓,但整体上有趋向好转的态势;在此基础上提出了有关地表水保护和水环境管理的几点建议.更多还原

【Abstract】 To realize the water quality status and evolution trends of Danhe River in recent years,based on the water quality monitoring data from 6 monitoring sections of Danhe River from 2004 to 2008,4 kinds of pollutants,such as COD,BOD5,NH3-N,Petroleum were selected which mainly affected the water quality of Danhe River,then water environment quality of Danhe river was assessed by fuzzy compreheusive evaluation method and its evolution of trends was also analysised by integrated pollution index method and spearman rank correlation coefficient method.The results showed that Danhe River pollution was serious and it belonged to class Ⅴ,especially,the sections of Gaoping and Shuidong bridge did.Protection of water environment was urgent,but the water quality was improved on the whole.At last,the relevant suggestions about surface water protection and water environment management were putted forward on this basis.更多还原
