The character of surface radiation and energy expended over soil temperature variation is that the temperature variation at surface, 5cm depth and 10cm depth are approximately sine curve on clear and cloudy day while this way the temperature variation at 20cm depth shows small extent anti - phase variation and the temperature under 50cm is no diurnal. in contrast, the temperature at 5m, 10cm and 20cm shows linear decrease and the soil - surface temperature is concaved on rainy day
地表輻射和能量耗散反映在土壤溫度變化上的特徵是晴天和陰天地表、 5cm 、 10cm的溫度變化表現為準正玄曲線， 20cm深處的溫度變化呈現出幅度很小的反位向變化， 50cm以下地溫已不存在日變化特徵；雨天5cm 、 10cm和20cm的溫度呈線性遞減，地表溫度表現出由降雨引起的凹陷現象。
