结果：获得疾病空间分布变异函数模型及其流行病学含义。
Results: The variograms model and its epidemiology implication were obtained.
方法：在疾病空间相关自相关假设下，构造疾病空间分布变异函数模型，应用变异函数计算HFRS的空间分维D值。
Methods:Based on the spatial correlation or autocorrelation hypothesis, the spatial semivariograms model of HFRS was built, and the fractal D of HFRS was calculated by its semivariograms model.
空间流行病学则是当中一个常被忽略的范畴，著眼于健康与疾病的地理分布。
Spatial epidemiology zooms in the geographic distribution health and diseases, an often neglected dimension of epidemiology.
