Thermal regime in shallow soil strata in loess plateau

By simulating the climate features on loess plateau,the loess ground thermal regime is deriked.By analyzing the calculated data and the tested data for the thermal regime,the changing law of the thermal regime caused by climatic change is explored.The relationship between loess temperature and loess depth in any month is given.It is pointed that the less the loess depth,the more the variation of temperature caused by climate change,and the more is the highest temperature and the less the lowest temperature.Further,this paper indicates that the more the loess depth is,the less is the variation of loess temperature caused by climate change.And the formula,by which the variation of loess temperature in any depth can be calculated,is arrived at.
