中国结核病的空间积聚性研究

Study on Spatial Clustering of Tuberculosis in China

目的探索中国结核病的空间积聚性,为我国因地制宜制定不同的控制措施提供科学依据。方法应用主成分分析、聚类分析和对应分析研究中国结核病的空间积聚性。结果(1)选取两个主成分作为我国结核病发生的综合指标。(2)聚类分析谱系图显示我国结核病的发生可分为3个主要空间分布区域,并在电子地图中标示出来。(3)制作对应分析图研究结核病发生的空间积聚性。结论将以上三种方法结合起来能更好研究疾病的空间分布和空间积聚性。

Objective To explore the spatial clustering of tuberculosis in China and to provide clues of implementing strategy of control. Methods Principle components analysis, clustering analysis and correspondence analysis were applied to analyze the spatial clustering of tuberculosis, Results （1）Two principle components were extracted to indicate the comprehensive assessment of the tuberculosis in China. （2） According to clustering analysis, three clusters were developed and the electronic map was made to illustrate the spatial distribution of the tuberculosis in China. （ 3 ） Correspondence analysis map was made to analyze the spatial clustering of tuberculosis. Conclusion The three methods together were suitable for analyzing the spatial distribution and spatial clustering of the disease.
