【摘要】：目的:探讨湖南省毒蕈中毒的空间分布及其影响因素,为科学防控毒蕈中毒提供依据。方法:收集2015年湖南省122个区(县)的毒蕈中毒监测数据,利用Arc GIS10.2软件建立病例地理信息数据库,采用Open Geo Da软件进行空间自相关分析和空间回归分析。结果:2015年湖南省毒蕈中毒报告发病率2.94/10万,病死率0.56%。全局空间自相关Moran's I值为0.315(P0.05),提示湖南省毒蕈中毒发病存在空间聚集性;局部空间自相关结果显示,毒蕈中毒发病热点区域为宁乡县、湘潭县、邵阳县、零陵区、嘉禾县、临武县等。冷点区域为古丈县、鹤城区、鼎城区、岳阳县等。空间回归分析显示,毒蕈中毒发病情况与年平均温度(Z=2.145,P=0.032)、人均卫生机构数(Z=2.352,P=0.019)、中学生人数(Z=4.309,P0.001)呈正相关,与中学教职工人数(Z= 2.626,P=0.009)呈负相关。结论:湖南省毒蕈中毒发病存在空间聚集性,发病主要集中在湖南省中部和南部地区,北部地区发病率较低。年平均温度、中学生人数在空间层面上对毒蕈中毒发病具有一定程度的正向影响作用。
[Abstract]:Objective: to investigate the spatial distribution and influencing factors of mushroom poisoning in Hunan Province, and to provide scientific basis for prevention and control of mushroom poisoning. Methods: the surveillance data of mushroom poisoning in 122 districts (counties) of Hunan Province in 2015 were collected. Case geographic information database was established by Arc GIS10.2 software, spatial autocorrelation analysis and spatial regression analysis were carried out by Open Geo Da software. Results: incidence rate of mushroom poisoning in Hunan Province in 2015 was 294,400, 000. The overall spatial autocorrelation (Moran's) I value is 0.315 (P0.05), indicating that there is spatial aggregation in the incidence of mushroom poisoning in Hunan Province, and the results of local spatial autocorrelation show that the hot spots of poisoning are Ningxiang County, Xiangtan County, Shaoyang County, and Lingling District, and the results of local spatial autocorrelation show that the hot spots of muscaric poisoning are Ningxiang County, Xiangtan County, Shaoyang County, and Lingling area. Jiahe County, Linwu County and so on. The cold spot areas were Guzhang County, Hecheng District, Dingcheng District, Yueyang County, etc. Spatial regression analysis showed that the incidence of toadbox poisoning was positively correlated with the annual average temperature of 2.145%, the number of per capita health facilities was 2.352%, the number of health facilities per capita was 0.019%, and the number of middle school students was Z4.309 (P0.001). Conclusion: the incidence of mushroom poisoning in Hunan Province is mainly concentrated in the central and southern areas of Hunan Province, and the incidence rate is relatively low in the northern part of Hunan Province, and the annual average temperature is low, conclusion: the incidence rate is negative correlation with the number of middle school teaching staff (Z = 2.626P0. 009). The number of middle school students has a positive effect on the incidence of mushroom poisoning at the spatial level.
