摘　　要：通过对海宁地表水质量状况进行监测与评价,为其质量提高提供数据支持和参考依据。在海宁市地表水中设置7个监测断面,且对其水质进行监测,并采用单因子评价法和综合水质标识指数法对地表水环境质量进行评价。结果表明,2017年总磷和生化需氧量是严重污染指标,平均Ci分别为0.85和0.78。各断面均受到不同程度的污染,其中上塘河和袁硖港相较于其他河流污染较为严重,综合水质标识指数都为4.000;但各河流水体均为Ⅲ类水质类别,水环境质量得到改善。To provide reliable data and reference for the improvement of water quality in Haining city, the way of monitoring and evaluation was used. Seven monitoring sections were set in surface water for the purpose of monitoring water quality, which was analyzed by using the signal factor assessment and the comprehensive water quality identification index method. The results showed that the total phosphorus and biochemical oxygen demand were significant pollution indicators in 2017, with an average Ci of 0.85 and 0.78, respectively. Each section was affected by different levels of pollution, of which Shangtang river and Yuanxia port were more seriously polluted than other rivers, and the comprehensive water quality index was 4.000. But the river water were Ⅲ class category, water quality of water environment quality was improved.
