摘　　要：对低丘红壤地区红壤性水稻土(黄筋泥田)和旱地红壤(黄筋泥)及不同利用方式下土壤的持水和供水特征进行了研究。结果表明,与红壤性水稻土相比,旱地红壤持水供水能力弱;红壤性水稻土各样品之间持水和释水能力的差异与有机质的变化相似,在红壤地区,培肥土壤有利于提高土壤抗旱能力,土壤利用方式不同改变了土壤孔隙的分布状况,使旱地红壤在低吸力段土壤的水分特征存在明显差异。This research was carried out on quaternary hilly red clay soil. Soil water-holding capacity and soil water release characters were analyzed. The results showed that the soil water holding and supplying capacity of upland soil was lower than the paddy soil. The variation of soil water holding and supplying capacity among paddy soil samples was similar to the variation of soil organic matter, it would improve soil drought resistance ability to fertilise the red clay soil. Soil water characters with different soil utilizations varied obviously in low soil suction, and different soil utilizations changed the distribution of soil pore.
