1988年8~9月,在河西走廊的化音和张掖地区进行了一次预备性观测实验。本文利用预备观测中所取得的少量资料,分析了干旱地区太阳辐射各个分量和太阳分光谱辐射的一些气候学特征。结果表明:该地区秋季大气透明度较好;光资源充足;兰紫光在总辐射中所占比例较大;地表净辐射具有平原地区的特征,其值介于平原与高原地区之间。

In September, 1988, a trial observation of the HEIFE was carried out at Huayin and Zhangye. Based on the collected observed data, the climatological characteristics of each component of solar radiation and spectral radiation over arid region have been analysed in this paper. The results are as follows: In that region during Autumn, the atmospheric transparency is higher; The solar resources is rich; And the energy ratio of blue-purple light in the total short-wave radiation was higher. The characteristic of surface net radiation is similar to that at plain region, which value is between that of Tibet Plateau and East Plain.
