摘要
地质统计学是用来分析空间相关变量结构的统计学方法。地质统计学中的变差函数和变差图,可分析空间变量在不同方向或不同环境条件下的空间结构(包括空间相关程度和范围以及空间连续性的大小)。用散点图、相关图和协方差方法来量化空间变异性,可以除去局部平均值和方差值的变异所引起的误差,从而更明确地进行空间结构分析。目前运用地质统计学研究昆虫种群空间结构的工作多集中在森林昆虫和大尺度昆虫方面。
Geostatistics has attracted the attention of many ecologists who need better explaining and modeling tools for describing spatial structure and patterns of organisms. This paper introduces the general methods of geostatistics, including variograms, h scatterplots, correlograms, covariance measures. Geostatistics is independent of mean variance relationship and therefore can be used to verify more traditional methods of evaluation insect spatial structure. A lot of works have demonstrated how to analyze spatial structure of insect population with geostatistics.
