[摘要] 目的：了解地理位置及地势特点对本市农村居民饮用水的影响，为改善居民饮水质量、预防水介疾病提供依据。方法：2005～2007年，根据不同地势特点(沿海、平原丘陵、丘陵山区)采用多阶段抽样方法，调查农村饮水情况。结果：总硬度、细菌总数、氯化物、总大肠菌群、铅、肉眼可见物、铁、pH、锌、氟化物、色度、溶解性总固体，其阳性检出率有显著性差异 (P<0.01)。对不同地势特点的饮用水中总硬度、铅、氯化物两两比较结果显示，平原地区高于其他两个地区，有显著性差异 (P<0.01)，其饮用水中细菌总数比较，以丘陵山区饮用水中细菌总数最高。结论：总硬度、细菌总数、氯化物、铅是影响本市农村居民饮用水的主要因素，氯化物含量与沿海岸线有关，丘陵山区细菌总数最高，建议不同的地理位置和地势特点，应采用不同的改水措施。
