摘　　要：为监测和评价鄂州市集中式饮用水源地周边土壤环境质量状况,选取2个具有代表性的市级集中式饮用水源地周边土壤为监测对象,对采集样品的理化指标、无机污染物和有机污染物共计14项指标进行了监测分析。采用单项污染指数法、内梅罗污染指数法对鄂州市2021年的土壤环境质量进行了评价。结果表明:2021年凤凰台、雨台山2个饮用水源地5个点位中有3个点位的土壤样品镉元素超过土壤污染风险筛选值,用内梅罗污染指数法评价,凤凰台水源地取水口及一级保护区的土壤状况为清洁(安全),二级保护区的土壤状况为尚清洁(警戒线),雨台山水源地取水口及二级保护区2个点位土壤状况均为轻度污染,一级保护区为尚清洁(警戒线)。研究结果为保护鄂州市集中式饮用水源地周边土壤的安全提供了理论依据。In order to understand the environment quality of the surrounding drinking water source in Ezhou city,two representative centralized drinking water sources,the Fenghuangtai water source and Yutaishan water source,were selected as the monitoring objects.Fourteen indexes including physical and chemical indicators,inorganic pollutants and organic pollutants in soil samples were measured.Single factor pollution index and Nemerow multi-factor pollution index were used to evaluate the soil environmental quality in Ezhou city in 2021.The results showed that the content of Cd of three sites soil around drinking water sources exceeded the screening value of soil pollution risk.Nemerow multi-factor pollution index illustrated that the quality of water intake and primary protected area at the Fenghuangtai water source was clean,the quality of secondary protected area was at the verge of cleanliness.The quality of water intake and secondary protected area at the Yutaishan water source was slightly polluted.The quality of primary protected area of Fenghuangtai water source was at the verge of cleanliness.The research result provided the theoretical basis for protecting the soil safety around the centralized drinking water source in Ezhou city.
