【摘要】 目的了解广西霍乱流行的地理分布特征及地理趋势。方法采用趋势面分析方法 ,建立趋势面数学模型 ,对广西1961～1999年霍乱累计发病率资料进行分析。结果发病率在经度108°～109°、纬度22°区域最高,在纬度25°的北部形成另三个高峰,在经度108°～109°带宽上其等值线变化频率最大。结论广西霍乱流行呈现四个地理趋势高峰值 ,以沿海地区发病率最高 ,其次为北部山区 ,流行趋势由南至北向内陆扩散 ,在经度108°～109°区域对地理位置的变化最具敏感性。更多还原

【Abstract】 Objective To study the geographic distribution of cholera epidemic in Guangxi.Methods The trend_surface analysis method was used.The prevalence data used in this article were cited from those between 1961₁999 in Guangxi.Results The incidence rate in the area lying on 108°～109° longitude and 22° latitude is the highest;other 3 high rates were found in the north of 25° latitude, and the biggest change of the equal incidence rate’s line was showed on the 108°～109° longitude area.Conclusion There were 4 high rate areas of cholera epidemic in Guangxi; the coastal area′s incidence rate was the highest and the second was in the mountainous region in the north of Guangxi. The cholera epidemic expanded into inland from south to north ,and had obvious characteristics of geographic distribution in the area of 108°～109° longitude.更多还原
