基于GIS四川茂县儿童结核病探索性空间数据分析

目的:探讨四川茂县儿童结核病发病率的空间地理分布模式及规律,为儿童结核病的有效防控提供科学依据。方法:采用地理信息系统(Geographic Information System,GIS)技术和空间统计分析方法对结核病相关资料进行分析处理。结果:海拔和人均年收入分布与儿童结核病发病率之间有明显的相关性(R=0.671,P=0.021和R=0.703,P=0.032);儿童结核病发病率地图和Moran's I空间自相关分析均显示结核病发病存在空间聚集性(Moran's Index=0.02,Z值为2.07),Local Mo-ran's I统计分析指出儿童结核病的高发热点区域。结论:四川茂县儿童结核病发病率呈明显的地域分布规律。

The exploratory spatial data analysis of childhood tuberculosis in Mao county based on Geographic Information System

Objective:To provide a scientific basis for preventing and controlling childhood TB by analyzing the geographical distribution and rules of the incidence of childhood TB in Mao county.Methods:Geographic Information System(GIS) technology and spatial statistical analysis methods were used to analyze the childhood tuberculosis data Results:Altitude and annual per capita income had a direct bearing on the incidence of childhood TB(P=0.021 1 and P=0.032).The incidence maps of childhood TB and Moran'sⅠspatial autocorrelation analysis showed that the spatial aggregation was in childhood TB(Moran's Index = 0.02,Z value of 2.07).Local Moran's I statistical analysis could point out the high incidence region of childhood TBConclusion:The incidence of childhood TB is obvious geographical distribution in Mao county of Sichuan province
