摘要： 用多个热敏电阻温度计对准格尔旗五道敖包坡梁地不同部位离地面30，80，150cm的气温进行测定，结果表明，黄土高原的沟壑地形中，同海拔高度南坡的温度较北坡高,有的高出0.3-0.5℃。近地面30cm的日平均气温一般高于150cm，有的位点白天温度平均高1.0℃,尤以光照条件好地方明显;而夜间近地面的温度相对较低。地形影响到温度差异，同时影响到降水的重新分配，进而将影响到作物的生长发育。

Abstract: The thermometers with heat sensitive resistance sensors were used to measure the air temperature of different sites and heights over ground 30cm, 80cm and 150cm of sloping and hummock at Wudaoaobao of Zhungeer. The result showed that the air temperature of south sloping were higher than that of north sloping at same height on donga landform of loess high plateau, at some sites the temperature of south sloping was higher 0.3℃ to 0.5℃ than north sloping. The mean air temperature of daytime at 30cm above ground was higher than that at 150cm, and at some sites the difference was higher than 1℃, and in night the temperature of 30cm above ground was lower. The landform affected air temperature of different sites and the re-distribution of rainfall, which would affected the crop growth and development.
