摘　　要：本文对古尔班通古特沙漠及其南部不同距离绿洲温度进行了分析。结果表明,由石河子至147团至150团至沙漠其温度变化幅度逐渐增大。各观测点气温变化呈单峰曲线,峰值均出现在14:00,从沙漠到石河子其峰值逐渐减小;地表、10cm和20cm温度峰值出现时间相继滞后2h左右,沙漠地表峰值比石河子、147和150分别高12.8、9.3和5.7℃。温度的梯度性分布是造成从沙漠边缘到绿洲腹地棉花生育期不同的原因,这对棉花的播种、田间管理等有一定的指导意义。In this paper the temperature is analyzed in Gurbantunggut Desert and oasis in different distance in the south. As a result,from Shihezi to 147 to 150 to desert the mutative extent of temperature is gently increasing. Change of the air temperature of every observation station is the monomial curve, and the highest temperature of them is at 14：00, from desert to Shihezi the highest temperature is gently reducing; the appearing time of the highest temperature of the ground, 10cm and 20cm drop behind 2h one after the other, compared with Shihezi, 147 and 150 the highest temperature of desert top respectively 12.8℃,9.3℃ and 5.7℃.The gradient distributing of temperature is the reason of different days from emergency to maturity of cotton from the edge of desert to hinterland of oasis. It has instructive significance for seed sowing and the management of field and so on.
