摘　　要：探讨了土壤温度的日、年变化规律及土壤温度梯度的变化特点,分析了土壤水分运动及土壤水和潜水之间的水分交换规律与土壤温度变化之间的关系。通过实验和分析证实,温度的日变化是引起浅层地下水位日变化的主要原因之一。The daily and yarly periodic variation regularities of soil temperature and characteristics of soil temperature gradient variation have been studied in this pa- per,the relationship between soil water movement as well as the exchange regulari- ty 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.
