摘　　要：内蒙古自治区境内有黄河、辽河、松花江、海河水系和内流河水系。内蒙古自治区环境监测中心站多年地表水监测数据显示:2010年,全区重点监测河流中约2/3的监测断面水质良好,达到地表水Ⅲ类标准;1/3的断面水质超标。主要超标指标为高锰酸盐指数、生化需氧量、石油类和氨氮,有机污染突出。重度污染河流主要分布于黄河支流。"十一五"期间,河流水质有机污染范围、程度整体呈减轻趋势,河流水质呈现稳定向好的发展态势。It contains Songhua River,the Yellow River ,｜iaohe River, Haihe River and the Inner River system In the territory of the In- ner Mongolia Autonomous Region. The surface water monitoring data in the Environmental monitoring center of Region shows that： in 2010, the significant monitoring of river in the region about 2/3 of the monitoring section water quality is good, which reach the surface water of class III standard; however 1/3section water quality exceed the standard. The main indicators which exceed the standard is potassium per- manganate index, BOD, petroleum and ammonia nitrogen, organic pollution. Severe pollution mainly distributed in a tributary of The Yellow River. In the period of Eleventh five - year plan, The range of river water quality organic pollution and the whole degree is alleviate, river water quality is stable to the good development situation.
