| Abstract: | The daily and yarly periodic variation regularities of soil temperature and characteristics of soil temperature gradient variation have been studied in this paper ,the relationship between soil water movement as well as the exchange regularity of soil water with phreatic water and soil temperature varition has also been ana lyzed . From experiments and analysis show that the daily periodic variation of tem perature is one of the main reasons causing the daily periodic variation of phreatic water table. |
