Using the relative reflection as weighting factor, the weighted mean of the surface albedo over Dunhuang Gobi in typical arid region is calculated and its values are 0.255 ± 0.021. After canceling the interference of the buildings, the mean values of the roughness length averaged with logarithm is 0.0019 ± 0.00071 m. After removing the influence of the oasis, the soil wetness factor computed with data under condition of no precipitation is 0.0045. After removing the influence of the precipitation .the mean values of the soil heat capacity over Dunhuang Gobi in typical ac-id region is 112 × 10 ~6 m~(-3)K~(-1), a bit smaller than the values observed i n HEIFE. But the soil heat diffusivity and conductivity are about one of those observed in HEIFE. The soil water content over Dunhuang Gobi in typical synoptic condition is very little and does not exceed 1% basically.

并且利用相对反射为权重加权平均，计算得到典型干旱区敦煌荒漠戈壁的平均反射率为0.255±0.021；剔除建筑物干扰后，利用对数平均法计算的粗糙度长度平均值为0，0019±0.00071 m；剔除绿洲影响后，用无降水影响的资料确定出土壤湿度影响因子为0.0045；剔除降水影响后，用观测资料计算的敦煌典型干旱区荒漠戈壁的热容量平均值为1.12×10~6m~（－3）K~（－1），比&黑河试验&在戈壁和在其它沙漠观测的有关值略小一些，但热扩散率和热传导率都比&黑河试验&在戈壁观测的值小一倍左右；观测的敦煌戈壁典型天气条件下的土壤含水量非常小，基本上不超过1％。
