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。
內矇古自治區境內有黃河、遼河、鬆花江、海河水繫和內流河水繫。內矇古自治區環境鑑測中心站多年地錶水鑑測數據顯示:2010年,全區重點鑑測河流中約2/3的鑑測斷麵水質良好,達到地錶水Ⅲ類標準;1/3的斷麵水質超標。主要超標指標為高錳痠鹽指數、生化需氧量、石油類和氨氮,有機汙染突齣。重度汙染河流主要分佈于黃河支流。“十一五”期間,河流水質有機汙染範圍、程度整體呈減輕趨勢,河流水質呈現穩定嚮好的髮展態勢。

It contains Songhua River ,the Yellow River ,liaohe 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 .
