| 摘 要： | 本文利用ＨＥＩＦＥ中绿洲（张掖）和沙漠两个测站１９９１年取得的观测资料，分析了两种不同下垫面太阳辐射能收支及其季节变化特征，结果表明：绿洲地区反射率明显小于沙漠区，季节变化明显；地面有效辐射绿洲小于沙漠，沙漠地区季节变化明显，绿洲则季节不明显；地表净辐射绿洲大于沙漠，不论冬，夏季该地区地面均为热源。

| Abstract: | In this paper,the characteristics of seasonal variation of solar radiation budget over two types underlying surface are analysed by using the data observed in oases(Zhangye) and desert in HEIFE in 1991 The results show that: in HEIFE region, the surface albedo is smaller in oases than in desert and its seasonal variation is obvious The effective radiation is also smaller in oases than in desert, its seasonal variation is obvious in desert and is not obvious in oases The surface net radiation is larger in oases than in desert and the surface heating fields act as a heat source whether in oases or desert for whole year |
