  1. During the course of the research, the criterions of the interpolation effect are mean error ( me ), mean absolute error ( mae ), root mean squared interpolation error ( rmse ) and the difference of mean square deviation between the measured and the estimated surface air temperature. the conclusions are as follows : ( 1 ) by contrasting the gaussian weighted model associated with the error modification with the gaussian weighted model, the error modification is proved to considerably ameliorate the precision of spatial interpolation ; ( 2 ) on the base of the gaussian weighted model, taking altitudinal effect into account can reflect the trend in which temperature changes according to the topographic altitude and may ameliorate the precision of spatial interpolation correspondingly and apparently, which indicates that topographical effect on the preciseness of spatial interpolation can not be disregarded in terms of the region with complicated topography ; ( 3 ) the map of daily surface air temperature distribution, using the modified gaussian weighted model a and b, can accurately reflect the temperature - changing - with - topographical - altitude trend. among them, the better is the model a, whose me is below 0. 03 ?

    在此過程中,採用平均誤差( me ) ,平均絕對誤差( mae ) ,插值平均誤差平方的平方根( rootmeansquaredinterpolationerror ,簡稱rmsie ) ,插值前後測站要素值的均方差( meansquaredeviation ,簡稱msd )差值作為判定插值效果的標準,得出如下結論:通過高斯權重法與結合逐步訂正的高斯權重法的對比,說明結合逐步訂正方案的高斯權重法可大大提高地面日氣溫的插值精度;在高斯權重法中加入海拔影響項可以反映出溫度隨地形高度的變化趨勢,同時也能較大地提高地面日氣溫的空間插值精度,說明在地形復雜的區域,地形影響在插值精度中是不可忽略的;對于高斯權重法的兩種改進方案得到的地面日氣溫分布圖都能很好地反映出表面大氣氣溫隨地形高度的變化趨勢。
