利用2005—2012年青海长江源区地表径流7个监测断面连续8年的地表水监测数据，分析长江源区地表水水质状况及变化趋势。结果表明：青海长江源区各监测断面Ⅰ～Ⅲ类水质比例为100％，区域地表水水质状况整体为优，水质为一级清洁；地表水中主要污染因子为CODMn、NH3-N和TP；地表水中元素浓度基本处于背景值状态，人类影响极微。
利用2005—2012年青海長江源區地錶徑流7箇鑑測斷麵連續8年的地錶水鑑測數據，分析長江源區地錶水水質狀況及變化趨勢。結果錶明：青海長江源區各鑑測斷麵Ⅰ～Ⅲ類水質比例為100％，區域地錶水水質狀況整體為優，水質為一級清潔；地錶水中主要汙染因子為CODMn、NH3-N和TP；地錶水中元素濃度基本處于揹景值狀態，人類影響極微。
이용2005—2012년청해장강원구지표경류7개감측단면련속8년적지표수감측수거，분석장강원구지표수수질상황급변화추세。결과표명：청해장강원구각감측단면Ⅰ～Ⅲ류수질비례위100％，구역지표수수질상황정체위우，수질위일급청길；지표수중주요오염인자위CODMn、NH3-N화TP；지표수중원소농도기본처우배경치상태，인류영향겁미。
The surface water quality and the variation trend around the Yangtze River Source Area were analyzed based on the monitoring data of surface water from 7 main monitoring cross-sections for successive 8 years from 2005 to 2012.The result shows that the water quality ratio in each monitoring section between Ⅰ and Ⅲ is 100%, which means that the overall condition of surface water in this area is optimal and the water quality grade is Class I . The main pollutants in surface water contain Permanganate, Ammonia nitrogen and 3 kinds of Total Phosphorus. However these element concentration in the surface water is at the state of background value, which hardly has impact on human body.
