目的旨在研究广西不同江河水质与区域霍乱流行的相关关系。方法利用我区1961～1999年霍乱疫情资料及1991～1999年广西24条河流流域水质监测资料，首次按江河区划统计霍乱流行强度，采用后退逐步回归法进行多因素相关分析。结果PH值、悬浮物、氨氮与区域霍乱发病呈正相关性，高锰酸盐指数、亚硝酸盐氮、硝酸盐氮与区域霍乱发病呈负相关性。结论PH值、悬浮物、高锰酸盐指数、氨氮、亚硝酸盐氮、硝酸盐氮是影响霍乱流行的相关因素，三高（PH值、悬浮物、氨氮）和三低（高锰酸盐指数、亚硝酸盐氮、硝酸盐氮）的水体区域易形成霍乱流行区。

Objective To study the correlation between the regional cholera and different water quality in Guangxi.Methods In order to study the intensity of cholera prevalence by dividing the river basins into districts for the first time, data on both epidemic situation of cholera from 1961 to 1999 and water quality surveillance for 24 river basins from 1991 to 1999 in Guangxi were collected. In this study,backward stepwise regression was used to analyze the multiple factor correlation analysis.Results There was positive correlation between PH,suspended matter,amino_nitrogen and the incidence of cholera. There was negative correlation between permanganate index,nitrite_nitrogen,nitrate_nitrogen and the incidence of regional cholera. Conclusion PH, suspended matter, permanganate index， amino_nitrogen, nitrite_nitrogen and nitrate_ nitrogen were interrelated factors which affected the prevalent of cholera. Higher PH, suspended matter,amino_nitrogen and less permanganate index,nitrite_nitrogen, nitrate_nitrogen are the availability facts for the water areas to become prevalent areas of cholera.
