三门峡水库是黄河流域上重要的大型综合性水利枢纽，然而由于区域社会经济及农业的快速发展，区域水环境质量以受到严重威胁，通过分析三门峡库区多年年平均水量水质的变化规律发现，区域水质呈逐渐恶化趋势，水体向劣Ⅴ类水转变，其主要污染物质为氨氮；通过分析三门峡库区多年水环境质量系数WQI变化规律发现区域水质呈逐年下降趋势；相关分析表明W Q I与水体中氨氮及COD含量显著相关，说明影响区域水环境变化的关键因子为氨氮及COD。

Sanmenxia Reservoir is an important large‐scale comprehensive water control project in the Yellow River basin .Because of the rapid development of the regional social economy and agriculture ,the water environment faces a serious threat .In this paper ,the changing process of water quality and quantity of the Sanmenxia Reservoir is analyzed .The result showed that water quality was on the trend of worsening and the main pollutant was ammonia nitrogen .The correlation analysis result showed that the water quality index (WQI) was associated with ammonia nitrogen and COD in water and the these two indicators was the key factor of regional wa‐ter environment change .
