Abstract

In this research, the variations and spatial distribution of soil heat capacity in soybean field and sugarcane field under drought, moderate and humid soil moisture conditions were studied. The soil heat capacity in order to analyze spatial distribution by geostatistical analyst in each plot covered was calculated by the measured soil moisture content, furthermore, the states of dry, moderate and wet soil moisture conditions were determined. The result showed the soil heat capacity was greatest in sugarcane plot but lowest in soybean plot, which was similar to the change of soil moisture content under three soil moisture conditions. It suggested that the soil water content was a primary factor resulting in the change of the soil heat capacity. According to the results of geostatistical analysis of soil heat capacity, the spatial structure ratio of soil heat capacity is 57% -93% under three soil moisture conditions, which belongs to strong moderate spatial relativity. The high threshold spatial distribution of soil heat capacity in soybean and sugarcane fields is stable under drought and humid conditions, which indicates that the soil itself has the ability to restore the stability of its spatial distribution.
