摘　　要：目的:探讨“等值线-面积”多重分形模型在识别疾病空间插值地图的绘图等级界限中的应用。方法:将分形理论与统计学方法相结合,以ArcGIS9.0为数据分析平台和绘图工具,构建疾病空间分布的“等值线-面积”多重分形模型。结果:构建了疾病空间分布的“等值线-面积”多重分形模型,提出了建模的基本步骤,并以肾综合征出血热空间异质性结构及其界限的识别为例,验证了模型的科学性和适用性。结论:利用“等值线-面积”多重分形模型所确定的疾病空间异质性结构及其界限能准确反映疾病空间异质性变化的本质规律。Objective： To explore the application of contour area muhifractal model （CAMM） in identifying the interval cut-off vales of mapping interpolated disease. Methods： Combine muhifractal with statistics in the framework of AreGIS9.0 to set up the CAMM. Results： The CAMM was set up, and its step-by-step procedure was presented. To validate its applicability in mapping disease, the structures and boundaries of spatial heterogeneity of hemorrhagic fever with renal syndrome （HFRS） were identified by using CAMM. Conclusion： The structures and boundaries of spatial heterogeneity of disease identified by CAMM can display the spatial characteristics of disease accurately.
