摘　　要：目的了解怀化市地下水水质状况,为集中式农村饮水安全工程的实施提供参考依据。方法对2005-2009年地下水水质检测结果进行统计分析。结果感观及理化指标Ⅰ-Ⅲ类水占93.4%,Ⅳ-Ⅴ类水占6.6%;各年度水质感观及理化指标检测结果比较,差异无统计学意义（P〉0.05）;细菌总数、大肠菌群总合格率分别为89.0%（162/182）、85.7%（156/182）。微生物指标各年度比较,差异有统计学意义（P〈0.05）。结论 5年间该市地下水水质稳定、水质较好。微生物及个别理化指标超标是不容忽视的问题。集中式农村饮水安全工程实施前,水源水质检测工作必须引起各级政府部门高度重视。Objective To investigate the quality of groundwater in Huaihua,and to provide the reference for the implementation of the centralized rural drinking water security engineering. Method The detection results of groundwater quality from 2005 to 2009 were statistically analyzed. Results According to the sense and physicochemical characteristics indexes,the water quality of grade Ⅰ～Ⅲ accounted for 93.4% and the water quality of grade Ⅳ～Ⅴ occupied 6.6%.No statistically significant difference was found in the detection results among each year（P〉0.05）.The total bacterial count and the total eligible rate of coliform bacteria were 89.0%（162/182） and 85.7%（156/182）,respectively.There was no statistically significant difference in the microbial indexes among each year（P〈0.05）. Conclusions The quality of groundwater during the period of 2005～2009 was stable and quite good,but that microbial indexes and few physiochemical characteristics indexes exceeded the standards could not be neglected.Therefore,the water quality detection of water resource must be highly emphasized in all levels of government departments before carrying out the centralized rural drinking water security engineering.
