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.
