中文摘要：
分别采用多元回归模型法、趋势面法、普通克里格法、反距离加权法和径向基函数法5种不同的空间插值方法,对内蒙古地区及其周边地区39a多年平均降水、相对湿度和气温进行空间内插方法优化进行了综合分析与比较。结果表明：以四球球面模型和合理二次模型为半变异函数模型模拟数据空间变化趋势的普通克里格法是内蒙古地区多年平均降水和相对湿度的最优空间化插值算法,以高次曲面方程为基本函数的径向基函数法是气温的最优空间化插值算法。
英文摘要：
A comprehensive analysis and comparison of optimized spatial interpolation methods was made to interpolate the average annual rainfall,relative humidity and atmospheric temperature from 1971-2009 by multivariable regression,trend,ordinary Kriging,inverse distance weighted and Radial Basis Functions in Inner Mongolia region.The results showed： OK with Tetraspherical and Rational Quadratic as semivariogram model is optimal spatial interpolation method in the process of imitating the spatial data trend of average annual rainfall and relative humidity respectively,RBF with Multiquadric functions as kernel function is optimal spatial interpolation method about average annual atmospheric temperature.
