摘要
使用Kriging插值、采用反距离权重法（IDW）、Spline插值方法对青藏高原气温进行空间插值比较研究。利用青藏高原10个实测站点数据与3种插值数据进行模拟，同时采用1A（一致性指教）来评价模拟的结果，3种气温插值结果与实测值之间的统计分析如下，IA分别为-0．81、-1．05、-1．73；插值精度效果最好的是Kriging，最差的是Spline。
The spatial interpolation of temperature on the Tibetan Plateau was carried out by using Kriging interpolation ,the inverse distance weighting method （IDW）,and Spline interpolation method. Ten actual site data and three interpolation data of the Tibetan Plateau were involved to complete the simulation, and the simulation results were evaluated by IA （consistency index）. The statistical analysis of three kinds of temperature interpolation results and measured values were as follows, IA were -0.81 ,-1.05 ,-1.73 respectively, Kriging method showed the best accuracy, while the Spline method worked worst.
