    Abstract
  • Two typical covering soil units located in karst hill in the Yaji Experimental Site in Guilin are chosen as the research object to analyze the moisture distribution and evaporation rate as well as the related influencing factors on soil profile. The result shows that (1)the soil maximum moisture content layer is located at the junction of the bottom soil and bedrock, the least moisture content at the middle transition layer soil, and the moisture content on the surface soil changes significantly with environments; (2)evaporation is high in summer, with the amount up to 10 mL to 12 mL in 10 cm soil column by day and 0 mL to 3 mL by night; (3)the main factors determining the diurnal evaporation （y） in short terms include solar radiation （x2） and soil temperature (x4),the equation is: y＝18.018+0.001x2-0.691x4.
