目的 运用地理信息系统技术, 描述三江源地区布鲁氏菌病(布病)的空间分布, 研究其空间流行特征。方法 建立三江源布病现况调查数据库, 采用QHEndem ic-GIS和SPSS 17.0软件统计、分析、制图, 以感染率、患病率叠加分析流行特征。结果 三江源地区布病现况调查的空间分布特征, 与考核期相叠加, 囊谦(2.00%/1.03%)、久治(0.81%/0.63%)、达日(0.58%/0.33%)县的患病率明显高于考核期。考核前后相叠加, 疫情均有上升之势。结论 地理信息系统技术可直观、准确地反映青海省三江源地区布病疫情现状, 区域内各县布病疫情呈散发, 并向周边县(区)扩散, 总体分析显示该地区布病疫情呈回升趋势。

Objective To describe spatial distribution of brucellosis in Three-River Regions and research its epidemiological characteristics with the Geographic information technique. Methods We established Geographic Information System Database of brucellosis in Three-River Regions, epidemiological characteristics were overlay analyzed in infectious rate and prevalence rate with QHEndem ic-GIS and SPSS 17.0. Results Spatial characteristics of brucellosis were showed in GIS, the overlaid prevalence rates in Nangqian(2.00%/1.03%), Jiuzhi(0.81%/0.63%)and Dari(0.58%/0.33%)in inspection period were higher than that in inspection period. Overlaying the prevalence of brucellosis before and after inspection period, the prevalence show an upward trend. Conclusion GIS could reflect the state of brucellosis in Three-River Regions directly and correctly. Prevalence of brucellosis showed a sporadic phenomenon with spreading the neighborhood region, the prevalence showed an up-ward trend in these region, and provide scientific data of brucellosis prevention and control.
