     摘要：目的探讨山东年肾综合征出血热(HFRS)疫源地的空间异质性。方法采用变异函数模型，对山东省1974～2004年的HFRS疫情资料进行定量分析。结果可将山东省HFRS疫源地空间异质性及其动态变化划分成5个阶段，且各阶段存在1个过渡年。结论 HFRS发病率的变异函数模型显示了山东省30年来HFRS疫源地空间结构经历了由简单到复杂，再由复杂到简单的变化过程。

    Abstract： Objective To explore the spatial heterogeneity of HFRS in Shandong province.Methods The model of variation function was used to analyze quantificationally epidemic situation data of HFRS in Shandong(1974～2004).Results The spatial heterogeneity of HFRS in Shandong province was divided into five periods and there was a transitional year among the periods.Conclusion Variation function model about HFRS incidence rate showed transformation process in spatial structure of HFRS infection focus in the last 30 years,which experienced from simple to complex and from comlpex to simple framework. ......
