在元谋干热河谷对桉树林、银合欢林、灌丛、草地和裸地5种土地利用类型0~100 cm土壤剖面的容重、总孔隙度、毛管孔隙度和非毛管孔隙度进行分析研究。结果表明：元谋干热河谷桉树林、银合欢林、灌丛、草地和裸地5种不同土地利用类型土壤容重在0~100 cm土壤剖面变化规律为随着土层深度增加,土壤容重增大;土壤总孔隙度和非毛管孔隙度随着土层深度的增加而减小;土壤毛管孔隙度较高,主要由土壤质地决定。元谋干热河谷地区土地利用方式不同造成土壤容重、总孔隙度、毛管孔隙度和非毛管孔隙度在土壤剖面上的分布差异。

The soil bulk density,soil total capillary,capillary porosity and non-capillary porosity of 5 different land use types in 0~100 cm soil profile were studied.The results showed that the soil bulk density increased with the increasing of soil depth in 0~100 cm soil profiles of 5 different land use types,but the change patterns of soil total capillary and non-capillary porosity were on the contrary.The soil capillary porosity was higher and it mainly depending on soil texture of dry-hot valley.The results suggested that the distribution differences of soil bulk density,soil total capillary,capillary porosity and non-capillary porosity in soil profile caused by the different land use types at dry-hot valley.
