摘　　要：2021年,研究团队选取深圳市龙岗区沙湾河进行水质监测,采用单因子评价法、单因子水质标识指数法、综合污染指数法、综合水质标识指数法和主成分分析法进行水质评价。结果表明:单因子评价法与单因子水质标识指数法一致得出氨氮、总磷是沙湾河水质的主要影响因子;综合污染指数法评价结果显示,沙湾河水质污染程度基本达到“较清洁”状态;综合水质标识指数法评价结果显示,沙湾河水质基本满足地表水Ⅲ类要求;主成分分析法评价结果显示,河流受有机物、营养盐影响较为显著,雨季水质仍有较大提升空间。本研究表明各种水质评价方法结果虽有差异,但能从不同角度反映河流水质状况,使用多种评价方法能充分挖掘水质数据的意义、更好反映河流水质特征。The research team used the single factor evaluation method,the single factor water quality identification index method,comprehensive pollution index method,comprehensive water quality identification index method and principal component analysis method to evaluate the water quality of Shawan River,Longgang District,Shenzhen in 2021.The results showed that the single factor evaluation method and the single factor water quality identification index method agreed that ammonia nitrogen and total phosphorus were the main influencing factors of Shawan River water quality.The comprehensive pollution index method showed that the water pollution degree of Shawan River basically reached the state of“relatively clean”.The evaluation results of comprehensive water quality identification index method showed that the water quality of Shawan River basically reached the standard with the surface water classⅲas the target of water environmental function zone.The evaluation results of principal component analysis showed that the river was significantly affected by organic matter and nutrient salt,and there was still a large space for improvement of water quality in rainy season.Although the evaluation results of various methods are different,they can reflect river water quality from different angles.Using multiple evaluation methods can fully explore the significance of water quality data and better reflect river water quality characteristics.
