景观流行病学研究中的资料分析方法

大部分流行病学资料具有空间属性、区域变量特征,特别是在群体和生态学层次上研究获得的资料。如常见的流行病学资料发病率问题,常表现为区域变量,随不同的空间位置和空间尺度而变化。这些资料既表现出常规资料的随机性,又具有疾病空间化变量的结构性。基于随机独立同分布假设的传统生物统计学无法正确分析具有空间异质性、空间自相关的流行病学资料。借助具有强大空间数据管理、分析能力的地理信息系统,并结合空间统计学,正确地处理分析流行病学资料是科学的分析方法。合理集成地理信息系统和空间统计分析,正确运用于景观流行病学中,实现两者的完美结合。

Analytical Method for Landscape Epidemiology Study

Objective Most data of epidemiology are spatial with the character of regional variables, particular for the data from the study based on Population level and Ecosystem level. For example, Incidence Of Disease in epidemiology has the character of regional variables, and varies with spatial scale and spatial location. The traditional Biostatistics, which hypothesis on random, the same distribution and independence, goes nowhere to analyze the data with spatial attributes and spatial autocorrelation. GIS has the strong capacity of managing and analyzing spatial data. It's scientific analysis way to draw assistance from GIS and integrate with Spatial statistics analysis to analyze spatial data. Reasonably combining GIS with Spatial Statistics and accurately applied to Landscape Epidemiology, Landscape Epidemiology and Spatial Analysis would be perfectly integrated.
