摘　　要：目的了解丹霞地貌地区居民生活饮用水水质和水性疾病现况,为保护水源、科学改水、防治疾病提供依据。方法在仁化境内不同海拔高度区域,选择有一定代表性的10个水厂监测点进行监测。在水质监测区域收集水性疾病信息,分析水质情况与水性疾病流行病学特征,分析两者相关性。结果检测生活饮用水157份,总大肠菌群、浑浊度合格率分别为31.21%、60.51%、是影响水质合格率的主要原因。总大肠菌群、浑浊度、菌落总数合格率在不同区域比较,差异均有统计学意义(P<0.05),相关分析显示p H、菌落总数合格率与海拔高度呈负相关(r=-0.830,P<0.05;r=-0.740,P<0.05)。介水传染病有一定的流行病学特征,不同区域介水传染病发病率比较,差异有统计学意义(P<0.05),伤寒和副伤寒、其他感染性腹泻发病率与菌落总数合格率呈负相关(r=-0.670,P<0.05;r=-0.674,P<0.05)。慢性非传染性疾病与水质无显著关系。结论仁化地区水质与其他地质区或其他丹霞地貌地区比较,有一定特点和规律。该地区水源虽未受到化学性污染,但总大肠菌群合格率偏低,应引起足够重视。水质对水性疾病有一定影响,为减少水性疾病发生,仍需加强水质处理,加大饮水工程建设力度。Objective To investigate the drinking water quality and the status of water-borne disease in Danxia landformarea and to provide a scientific basis for protecting water sources, improving water quality, preventing and controlling water-borne diseases. Methods Ten monitoring sites in different altitude were selected from the representative water plants inRenhua county of Danxia landform. Data of water-borne disease were collected from the area of water quality monitoring. Thenthe drinking water quality and the epidemiological characteristics of water-borne diseases were analyzed; Correlations betweenthe two were analyzed at the same time. Results A total of 157 samples were detected. The qualified rates of total coliformgroup and turbidity were 31.21% and 60.51% respectively.Significant differences in the qualified rates of total coliformgroup, turbidity, total bacterial count were observed between different regions（P〈0.05）. Significant negative correlations werefound between altitude and the qualified rate of p H（r =-0.830, P〈0.05） as well as the qualified rate of total bacterial count（r =- 0.740, P〈0.05）. Water- borne diseases accorded with certain epidemiological characteristics, there was significantdifferences in the incidence of waterborne infectious diseases between different regions（P〈0.05）,significant negativecorrelations were found between the qualified rate of total bacterial count and the incidence of typhoid and paratyphoid fever（r =-0.670, P〈0.05）as well as the incidence of other infectious diarrhea（r =-0.684,P〈0.05）. No significant association wasnoticed between chronic non communicable diseases and the water quality. Conclusion Compared with other geological areaor other Danxia landform areas, the drinking water quality in Renhua area possesses particular characteristics and rules.Though the water in Renhua area is not subjected to chemical pollution, the qualified rates of total coliform group is relativelylow.
