Abstract:: The seep rate of soil water,soil water content, soil temperture, soil evaporation, leaf transpiration were determined. The results showed that the order of the seep rate of soil water was 2 m×4 m>1.5 m×2 m>CK after water was added for 0~4 hours and the varying range of soil water content of 2 m×4 m forest was greatest (+2.09%), whose increased value were 1.47 and 4.18 times more than CK and 1.5 m×2 m forest. The highest temperature of soil in 2 m×4 m forest appeared at 16:00, and higher temperature of soil in 1.5 m×2 m forest appeared during 14:00-18:00. Soil evaporation of 2 m×4 m forest was larger than that of 1.5 m×2 m forest in all day. The total forest evaporation of 2 m×4 m forest [2.47 g/(dm²·d)]was higher than that of 1.5 m×2 m [0.91 g/(dm²·d)]. The total leaf transpiration of 1.5 m×2 m forest [111.47 g/(dm²·d)] was higher than that of 2 m×4 m forest [87.81 g/(dm²·d)]in all day.
