摘要
目的利用地理信息系统(Geographic Information System,GIS)技术探讨2005—2012年云南省野生蕈中毒的地理分布特点,并分析与云南省野生蕈中毒有关的重要环境因素影响状况,为有效防控野生蕈中毒提供科学依据。方法收集2005—2012年云南省野生蕈中毒事件数据和有关的环境资料,运用MapInfo 7.8软件制作野生蕈中毒事件地理分布图,采用多因素线性回归分析法探讨野生蕈中毒发生与环境因素的关系。结果 2005—2012年云南省共报告野生蕈中毒事件187起,地理分布上有2个聚集区,分别位于滇东南文山州的广南县、文山市、砚山县、丘北县,以及滇西南普洱市的澜沧县、孟连县,临沧市的沧源县、凤庆县,西双版纳州的勐海县。年均气温、年均降水量与野生蕈中毒发生的高低存在一致性,纬度、农村居民年人均纯收入则存在反一致性。结论云南省野生蕈中毒具有明显的地域分布规律,相关部门应根据其发生的地理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 geographical distribution characteristics of wild mushroom poisoning in Yunnan Province from 2005-2012 by Geographic Information System, and analyze the effect of important environmental factors, and provide scientific evidence for developing control strategies. [Methods]Data of wild mushroom poisoning incidents and the relevant geographical information in Yunnan province from 2005 to 2012 were collected. MapInfo 7.8 software was used to make thematic map. The relevance of wild mushroom poisoning and geographical factors was analyzed through using multivariate linear regression. [ Results ] There were 187 wild mushroom poisoning events reported from 2005-2012. Two gathering areas located in southwest （ Canton County, Wenshan City, Yanshan County, Qiubei County of Wenshan Prefecture ） and southeast （ Lancang County, Menghan County, Lincang Cangyuan County, Fengqing County of Pu＇ er City and Menghai County of Xishuangbanna Prefecture ） of Yunnan province. Consistency was found between annual average temperature, annual precipitation and the prevalence of wild mushroom poisoning, while anti-consistency was found between latitude and annual per capita net income of rural residents. [ Conclusion] The prevalence of wild mushroom poisoning is obviously distributed geographically in Yunnan Province. Relevant departments should develop effective measures, based on the geographical distribution of its occurrence characteristics and related factors.
