摘要
以甘肃省53个气象台站多年平均降水量和蒸发量为研究对象,运用地统计学分析方法,通过比较分析,分别采用指数模型和球状模型对降水量和蒸发量的半变异函数进行了拟合,并且应用克立格插值生成了年降水量与蒸发量的空间分布图,直观分析了研究对象的空间变异规律。
In the paper, Geostatistic method was used to analysis the spatial variations of the average year precipitation and transpiration from 53 meteorological stations in Gansu Province. Through comparison and analysis, using Exponent model and Spherical model to calculate the semivariogram of them separately, spatial distribution maps were generated according to Kriging interpolation method. It analyzed gently the space Mutant law of the Object of the study.
