    研究結果表明： 1太白山南坡土壤的主要理化性質隨海拔高度的上升呈有規律的變化：隨海拔高度上升，機械組成由粉粒砂粒粘粒逐漸過渡到砂粒粉粒粘粒，海拔1600m以下出現粘化層；土壤有機質豐富，表層有機碳含量一般在20g kg以上，有機碳含量隨海拔高度升高而相應增加，海拔3500 3700m的灌叢草甸植被下有機碳含量最高；土壤呈酸性或微酸性，並隨海拔上升， ph值略微降低，酸性增強，海拔2700m以上的土壤多呈鹽基不飽和狀態，表明土壤淋溶作用較強， ph值和鹽基飽和度呈極顯著正相關；土體與粘粒中的sio _ 2 、 al _ 2o _ 3 、 fe _ 2o _ 3含量相對比較穩定，土體中sio _ 2含量較高， cao含量較少， sio _ 2 、 al _ 2o _ 3和fe _ 2o _ 3含量之和約占土壤礦質部分的92 ，礦質元素含量的順序依次為： sio _ 2 al _ 2o _ 3 fe _ 2o _ 3 k _ 2o mgo cao tio _ 2 mno 。
  2. Besides, the information on actual height of lowest cloud base is used in constructing of cloud liquid water profile by using radiosonde profiles, that makes an improvement of relative accuracy of retrieved value of l at almost all altitudes by 5 - 20 % according to numerical simulation comparison. the lower the altitude is, the more the accuracy is improved

    為減少由於回歸樣本中雲液水廓線的『失真』給反演造成的誤差，本文在對探空廓線作診斷建立雲液水廓線時，引入了實際目測的最低雲底高的信息。數值模擬比較表明該措施行之有效，使對流層中下層的幾乎所有高度上l反演值的精度提高5 - 20 ，觀測高度越低，精度提高越多。
  3. 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。
