The results showed that in the four rehabilitated forests, the previous month's soil moisture content had stronger effects on the current month's soil moisture content in 0-40 cm and 20-40 cm layers, but had lesser effects on that in 0-10 cm layer. The soil moisture content in 20-40 cm layer was mainly affected by current month's precipitation, while that in 0-10 cm layer was mainly affected by current month's evaporation. The correlation coefficient between current month's precipitation and soil moisture content was the largest in pure Liquidambar formosana plantation, and the auto-interrelation coefficient of soil moisture content was larger in mixed forests than in pure L. formosana plantation.

结果表明：研究区各重建森林前一个月的土壤含水量对当月整个土壤剖面(0~40 cm)平均土壤含水量和当月20~40 cm土层土壤含水量具有较强影响，对当月0~10 cm土层土壤含水量的影响较小；研究区各重建森林20~40 cm土层土壤含水量主要受当月降水量的影响，0~10 cm土层土壤含水量主要受当月蒸发量的影响；在4种森林重建模式中，枫香纯林当月降水量与当月土壤含水量的相关系数最大，混交林模式土壤含水量的自相关系数大于纯林模式。
