摘　　要：为了解徐州市集中式地表饮用水源地达标建设完成后的水质状况,采用单因子评价法和季节性Kendall检验法进行水质评价和变化趋势分析。结果表明:全市7个水源地水质稳定在Ⅱ~Ⅲ类,6年达标率均在97%以上,满足供水要求。分析得出了水源地主要污染物指标及变化趋势,对7个水源地存在的水质风险逐一进行了成因分析,提出了水源地保护的合理化建议。To understand the water quality status of centralized surface drinking water sources in Xuzhou City after the completion of standard construction,the single-factor evaluation method and seasonal Kendall test method were used for water quality evaluation and trend analysis.The results indicate that the water quality of all seven water sources in the city remains stable within Class II to III,with a compliance rate of over 97%for six years,meeting the requirements for water supply.The paper identified the main pollutant indicators and their trends and analyzed the causes of water quality risks for each of the seven water sources,providing rational suggestions for water source protection.
