中文摘要	利用2年沙漠边缘至绿洲4个观测点的气象资料，计算得到感热通量、湍流热量、净辐射、同一高度的气压等，讨论这些要素的时间和空间变化规律，解释绿洲至沙漠气温逐渐增加的原因，以对沙漠增温效应做出进一步的分析，为发挥特定地区的农业气候资源优势，促进农业结构调整和区域经济发展及构建新型农业技术体系提供理论基础。
英文摘要	Located in a zone between the Tianshan Mountains and the Altay Mountains, the Junggar Basin is the second largest basin in China, the terrain slopes westward, and the average elevation of the basin bottom is less than 500 m a. s. 1. Gurbantonggut Desert, the second largest desert in China, is located in the Junggar Basin, its area is 48 000 km^2, the most dunes in the desert are fixed and semi-fixed, the vegetation coverage of the fixed dunes varies in a range of 40 % -50 % and of semi-fixed dunes 15 % -12 % ; the annual air temperature and precipitation vary in ranges of 4.3 - 7.9 ℃ and 70 - 150 mm respectively, and the seasonal snow cover depth is 10-20 cm and 30 cm in maximum. In this paper, the sensible heat flux, latent heat flux, net radiation, air pressure, etc. in the southern marginal zone of the Gurbantonggut Desert are calculated based on the meteorological data observed in the southern marginal zone of the Gurbantonggut Desert in recent 2 years and 4 meteorological stations in oases by applying atmospheric thermodynamics theory, and the temporal and spatial changes of these factors are analyzed so as to explain the causes resulting in the temperature increase in the Gurbantonggut Desert and its southern marginal zone as well as the oases. Moreover, the effects of temperature increase of the desert are analyzed so as to provide the theoretical basis for making the agroelimatic resources into full play, promoting the regulation of agriculture structure and regional economic development, and structuring the advanced farming technical system.
