Abstract:: Based on geostatistical method and GIS,the paper uses several interpolation methods to estimate the weather data on Loess Plateau.The result of geostatistical method is better than the reverse distance weighting method,polynomial interpolation method and radial basis functions method.The Simple Kriging is the best interpolation method to annual average rainfall;in consideration of great influences of the elevation information.It is taken as an influencing factor of the second class,and introduced into the Co-Kriging method for spatial interpolation,Simple Co-Kriging is best to annual average temperature on Loess Plateau.Annual average rainfall and annual average temperature in southeast are much than northwest on Loess Plateau,the ambit is clear.The annual average rainfall is 117~721 mm,and the annual average temperature is 7.0~14.0℃,so the climate of Loess Plateau suits agriculture and animal husbandry.
