摘　　要：目的了解某市农村生活饮用水水质动态变化及其影响因素。方法在该市所辖三个县于2009-2012年共设置458个水质监测点,在每年3月、8月分别进行枯水期和丰水期水样的采集,检验和评价。结果水样合格率为86.24%,三县农村水质监测差异有统计学意义(P<0.01),B县丰水期、枯水期水质监测合格率均低于三县平均合格水平。检测指标中,感官、一般化学指标及毒理学指标合格率均在99.5%以上,微生物指标合格率最低。结论该市农村水质监测存在地区差异,丰水期微生物污染是该市农村生活饮用水水质合格率较低的主要原因。Objective To understand the influencing factors of dynamic change of the drinking water quality in rural area in one city.Methods 458 water quality monitoring stations were build up in 3 counties（A, B, and C county） in the city from 2009 to 2012. For the dry season and the wet season collection, inspection and evaluation of water samples were carried out at March（for the dry season） and August（for the wet season） in every year. Results The qualified rate of water samples was 86.24%. There were significant differences in the water quality of the three counties（P〈0.01）. During the same dry season and wet season, the qualified rates of water quality in B county were lower than the average level of the three county. Of the testing indicators, the qualified rates of sensory, general chemical index and toxicology index were more than 99.5%, and the qualified rate of microbial indicators was the lowest. Conclusion There are regional differences in the water monitoring in the city, and the microbial contamination in the wet season is the main reason for the low qualified rate of drinking water in the rural area.
