摘要：在毛竹分布南缘的中亚热带与南亚热带气候过渡区,选择土壤类型、坡度、坡向、经营水平等一致的3个海拔梯度毛竹林,对土壤物理性质和水分特性指标进行了测定,结果表明:相同海拔梯度毛竹林随土层的加深,土壤容重、总孔隙度、非毛管孔隙度、饱和持水量、田间持水量、粘粒和砂粒含量增大,而毛管孔隙度和粉粒含量减小;海拔对毛竹林30 cm土层的土壤容重、总孔隙度、毛管孔隙度、田间持水量影响不显著,而土壤非毛管孔隙度、饱和持水量随海拔升高而显著增大;不同海拔梯度毛竹林30 cm土层的土壤微结构颗粒组成为砂粒>粉粒>粘粒,粘粒、粉粒含量随海拔升高而减小,砂粒含量趋于增大;试验区随海拔的升高,土壤物理性质和水分特性趋于有利于毛竹林生长变化。
The three moso bamboo plantations with the same soil type, slope gradient, slope aspect, and management level at three altitudes were chosen to study the physical properties and moisture characteristics of soils in the areas between middle subtropical and south subtropical. The results showed that with the soil depth increasing, soil bulk density, total soil porosity, non-capillary porosity, saturated water capacity, field water capacity, and content of sand and clay increased in the moso plantations at the same altitude, but capillary porosity and silt content decreased. In the depth of 0 - 30 cm, the altitude had no significant influences on soil bulk density, total soil porosity, capillary porosity, and field water capacity, but non-capillary porosity, saturated water capacity increased significantly with the altitude increasing. The content of silt in the soils （0 -30 cm） was greater than the clay content but less than the sand content in the three altitudes, and with altitude increasing, silt and clay in soil decreased, but sand increased. Consequently, the physical properties and moisture characteristics of soil were tended to be beneficial to the growth of Moso bamboo with the altitude increasing.
