摘　　要：对古尔班通古特沙漠及其南缘绿洲间各观测点的热通量、波恩比和净辐射进行了分析.结果表明,从沙漠到绿洲,下垫面获得的净辐射热量中,感热通量和土壤热通量所的占比例逐渐减少,而潜热通量的比例逐渐递增,离沙漠越远潜热通量越大;在12:00～18:00,绿洲裸地上波恩比在2.0～8.9变化,而在沙漠边缘为10～11;早上和晚上沙漠的净辐射高于绿洲,白天近地面净辐射绿洲大于沙漠.Based on the experiments conducting at Gurbantunggut Desert and its south oasis of observation stations, the latent heat, Bowen ratio and net radiation have been analysised. The results show that the ratios of the absorbed to the incoming radiation by the underlying surface from Shihezi oasis to the sand area the sensible heat flux and soil heat flux makes up little proportion, which sensible heat shows increasing and the latent heat further inseasing far from the desert. Bowen ratio ranges from 2.0 to 8.9 during 12：00 to 18：00 in oasis nakedly while 10 to 11 in the edge of the desert.The clean radiation of the morning and the evening of desert is higher than in oasis, the district facing the clean radiation oasis in the daytime is big in desert.
