Study on spatial heterogeneity of hemorrhagic fever with renal syndrome(HFRS) in Shandong province

ObjectiveTo explore the spatial heterogeneity of HFRS in Shandong province.MethodThe 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.ConclusionVariation 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.
