摘　　要：在地理信息系统教学的上机实验中,通过分析区域化变量理论,选取塔里木河流域日平均降水的Hurst指数H1与其他属性为实验数据,以ArcGIS 10.2软件平台为基础,利用地统计学内插方法——联合克利金法(CoKriging)对指数H1进行空间插值.结果表明,CoKriging可以精确地展现流域降水变化的长记忆性空间分布规律.This paper firstly analyzes the basic principle of geostatistics, that is regionalized variable. Then Hurst indexH1 of the average precipitation in the Tarim River Basin and other properties including longitude, latitude and elevation of 23 meteorological stations are used to experiment data. In the ArcGIS 10.2, Hurst indexH1 was interpolated using geostatistical interpolation CoKriging method. Results show CoKriging method can accurately present the spatial distribution of long memory of precipitation change in the Basin.
