鄂尔多斯市水环境质量评价和水功能区管理研究

Research on Ordos City's Water Environment Quality Assessment and Water Function Area Management

水环境质量评价已成为当前水功能区管理,以及水环境综合整治的一项基础工作。对鄂尔多斯16条典型河流水质检测分析,并运用单因子标识指数法,确定影响鄂尔多斯典型河流水质的主要因素为溶解氧、高锰酸盐指数、化学耗氧量、氨氮、总磷和总氮;运用综合标识指数法对分析结果进行评判分析得到,16条河流中2条河流水质不达标,其他河流的水质达标。

Recently,Water environment quality assessment has become a key word in water environment quahty assessment and water function area management.Ordos＇s 16 typical rivers water quality is analyzed in this research.The results show that the main factors in influencing water quality are dissolved oxygen,permanganate index,chemical oxygen demand,ammonia nitrogen,total phosphorus and total nitrogen based on the single factor water quality identification index.Analytical results are assessed on comprehensive identification index method,two rivers water quality is not up to the water standard,the others meet corresponding standards.
