摘　　要：[目的]揭示细菌性痢疾的季节性变化特征,为制定防治策略和采取有效控制措施提供科学依据。[方法]应用集中度及圆形分布法对1990～2007年广西细菌性痢疾的流行季节特征进行分析。[结果]1990～1999年广西细菌性痢疾流行的集中度M值0.37,2000～2007年为0.27。两个时段间的发病高峰日、高峰期及时间跨度分别为6月17日、3月26日～9月7日、164d及6月3日、2月27日～9月7日、192d。[结论]广西细菌性痢疾流行的季节性在逐渐减弱,应做好全年的防控工作。[ Objective] To reveal the seasonal changes of bacillary dysentery and provide scientific basis for the control strategy and measures. [Methods] Concentration and circular distribution method were employed to analyze the epidemic seasonal characteristics of bacillary dysentery from 1990 to 2007 in Guangxi. [Results]3 The concentration degree （M Value） of bacillary dysentery from 1990 to 1999 was 0.37, and the M value from 2000 to 2007 was 0.27. The epidemic peaks, peak periods and peak days in 1990-1999 and in 2000-2007 were June 17, March 26 to September 7 and 164 d and June 3, February 27 to September 7 and 192 d, respectively. [Conclusion] The seasonal distribution feature of bacillary dysentery in Guangxi is being weakened gradually. Prevention and control measures should be taken during the whole year.
