【摘要】 根据田间土壤采样数据，利用地理信息系统（ＧＩＳ）中的地学统计方法生成田间肥力分布图，是了解田间土壤肥力差异的重要手段，通过对克里金法、移动平均法、二次样条插值法三种地学统计方法进行试验比较，得出克里金法是一种较适宜的生成田间肥力分布图的地学统计方法。更多还原

【Abstract】 Map of field fertility can be made by geostatistical methods of GIS according to soilgrid samples. This map is an important method to learn variety of the field soil. Compared withthree geostatistical methods (Kriging, Bilinear, Inverse distance two), Kriging is tested asappropriate method to make map of soil index.更多还原
