基于GIS的四川茂县儿童结核病疫情趋势面分析

The trend-surface analysis of childhood tuberculosis in Maoxian based on Geographic Information System(GIS)

【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)技术和趋势面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);儿童结核病发病率高发区分布以雅都乡、曲谷乡、维城乡、洼底乡为中心,且随着与该地区的距离的加大,发病率逐渐降低。【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] Providing a scientific basis for childhood tuberculosis（TB） prevention and control by analysising the geographical distribution of spatial patterns and rules of the Maoxian＇s incidence of childhood TB cases. [ Methods] Geographic Information System（GIS） technology and spatial statistical analysis methods of childhood TB data. [Results] The obvious relevance between altitude, annual per capita income and childhood TB morbidity （r= 0. 671,P= 0.021 and r= 0.703, P = 0. 032） ; the center of high-incidence area of childhood TB distributed to Yadu, Qugu, Weicheng, Wadi townships,and with distance from the region increased, the incidence decreased. [Conclusion] Sichuan Maoxian incidence of childhood TB cases are obvious geographical distribution.
