摘　　要：对古尔班通古特沙漠及其南部不同距离绿洲的气温以及不同深度的土温进行了比较分析。结果表明,沙漠地表温度和气温升降速度比绿洲观测点要快、变化幅度大;在局地环流和“城市热岛效应”的共同作用下,10:00～12:00石河子市气温的升温幅度大于沙漠,但沙漠特殊的下垫面性质以及地理条件,使得沙漠温度仍然高于绿洲;沙漠成为影响绿洲气候和农作物生长发育的生态区,使绿洲具有比同纬度地区优越的热量资源;从沙漠边缘到石河子市,春季各农业界限温度的稳定通过日期逐渐提早,这为棉花等绿洲优势作物的播种期、物候期、作物生育及生理生态特性研究与生产具有一定的指导意义。In this paper the air temperature of different depth of soil compared with that of soil in Gurbantunggut Desert and oasis in the south different distance of it. The analysis results indicate that the ascending and descending speed of ground temperature and air temperature of desert are greater than that of oasis and the variable extent of it is greater than that of oasis. With the combined action of partial circumfluence and urban heat island, the increasing extent of temperature of Shihottze is greater than that of deserts between 10：00 and 12： 00, but the special character of underlying surface and geographical condition of desert still make the temperature of the desert be higher than that of oasiss and the desert become the ecological area which influences the climate and growth of agricultural crops in the oasis which makes it obtain more advantageous heat sources than that in the same latitude. It is found that the limit temperature in different agricultural areas every spring gradually comes ahead of time, which is advantageous to season of sowing, phenological period, growth and ecological characters of crops.
