摘　　要：目的利用地理信息系统（geographic information system,GIS）技术探讨2005—2013年云南省野生蕈中毒的时空分布特点,为野生蕈中毒防控提供科学依据。方法采用描述流行病学方法,对云南省野生蕈中毒事件进行分析,运用Map Info 7.8软件制作野生蕈中毒事件空间分布及动态变化图,并采用全局空间自相关Moran＇s I系数探测云南省野生蕈中毒的空间分布模式,最后用局域自相关Gi^＊统计量探测聚集位置与属性。结果 2005—2013年云南省共报告野生蕈中毒事件211起,每年中毒高峰为5~9月。局域空间自相关分析结果显示文山州的广南县、文山市、砚山县、丘北县,普洱市的澜沧县、孟连县,西双版纳州的勐海县、景洪市为野生蕈中毒高发区域。中毒区域还在不断扩大,并逐渐向滇西北、滇东北扩散。结论云南省野生蕈中毒在时间上具有明显的季节性,空间上存在地域分布规律,相关部门应根据其时空分布特点及相关影响因素,制定野生蕈中毒的防控措施。Objective To explore the wild mushroom poisoning space-time distribution characteristics in Yunnan Province in 2005-2013 with geographic information system,and provide scientific evidence for prevention strategy. Methods Descriptive epidemiology was used to analyze the wild mushroom poisoning events in Yunnan province. Map Info 7. 8 software was used to make thematic map. A global means of spatial autocorrelation with Moran＇s I was used to explore the whole spatial distribution pattern of the wild mushroom poisoning incidence in Yunnan Province. The location and intensity of cluster were detected by the local spatial autocorrelation statistic. Results There were 211 wild mushroom poisoning events reported from2005 to 2013. The poisoning peak occurred in 5-9th month annually. Local spatial autocorrelation analysis revealed several counties had cluster such as Guangnan county,Wenshan county,Yanshan county,Qiubei county,Lancang county,Menglian county,Menghai county,and Jinghong county. Poisoning area was still gradually expanding to the northwest and northeast.Conclusion The wild mushroom poisoning events prevalence was obviously distributed seasonally and spatially in Yunnan Province and effective measures should be taken to control its prevalence.
