基于GIS四川茂县儿童结核病探索性空间数据分析

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

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。

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 ＇s Ⅰ spatial autocorrelation analysis showed that the spatial aggregation was in childhood TB （ Morang 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
