摘　　要：目的掌握江苏省农村饮水状况,为改进制水工艺,提高饮水质量提供科学依据。方法于2007年1～10月,调查检测江苏省苏南、苏北、苏中地区的13个省辖市、53个县(市)农村饮用水集中供水单位和分散式供水。结果农村饮水综合评价合格率为41.34%,余氯、浑浊度、总大肠菌群、细菌总数、氟化物合格率分别为49.64%、85.75%、79.69%、88.78%、92.63%,其余指标合格率均在95%以上。由南至北地表水占比重,苏南>苏中>苏北。水氟化物含量主要在浅表层地下水,淮河水系>长江水系。总大肠菌群、浑浊度长江水系>淮河水系。细菌总数两水系无显著差异。水锰含量主要在地表水、浅表层地下水,长江水系>淮河水系。镇江、盐城、淮安、徐州水砷高于其他地区。结论江苏省农村饮用水总合格率低,部分地区水氟、砷含量高。Objective Master the state of countryside drinking water in Jiangsu Province, so as to provide scientific evidence for improvting produce craft and water quality for rural people. Methods Investigate the hygiene situation in southern, northern and central region that cover centralized supply water and decentralization supply water unit including 13 cities managed directly by the province, totally 53 counties （cities）. Results The rural comprehensive appraisal on qualification rate of drinking water is 41.34%. The countryside drinking water qualification rate of chlorine, turbidity, total large intestine fungus herd, total number of bacteria, fluoride is 49.64 % , 85.75 % , 79.69 % , 88.78 % , 92.63 % respectively. The qualification rate of other indexes is above 95 %. The surface water proportion in southern region is greater than central region, which is greater than that of northern region. The water fluoride is mainly in the shallow floor groundwater. The water fluoride in Huaihe River system is greater than that in Yangtze River system. The total large intestine fungus herd, total number of bacteria in Yangtze River system is greater than that in Huaihe River system. The total number of bacteria in the two water systems has no significant difference. The content of manganese is mainly in surface water and shallow layer groundwater. The content of manganese in Yangtze River system is higher than that in Huaihe River system. The content of arsenic in Zhenjiang, Yancheng, Huai＇an, Xuzhou City is higher than that in the others. Conclusions The qualification rate of rural drinking water is low and the content of fluoride and arsenic are higher in some region of jiangsu Province.
