摘要
介绍一种研究区域生物灾害空间分布的方法：基于区域化变量理论的克立格插值技术，包括空间半变异方差的计算及其曲线的拟合，克立格内插权重的推导，以及待估点内插值的计算．通过构造一个简单例子，说明该方法在生成区域生物灾害空间分布情景中的独特作用。
A method named Krige interpolation, based on regionalized variable theory, was presented for the study of regional disaster of pests, including the calculation of semivariogram and its simulation, the solution of weights of samples used in interpolation, and the estimation of values of unknown points. The major advantage of presented method seems to be obvious in generating the spatial scenario of regional disaster of pests through the given example.
