摘　　要：阐述了南亚热带低山、丘陵、台地赤红壤总库容、贮水库容、通透库容的占有情况。探讨了水库容的有效性以及不同利用方式的赤红壤有效水库容与无效水库容的差异，并对影响赤红壤水分有效性的因素作了分析．结果表明：赤红壤贮水库容小，尤其是有效水库容小；赤红壤水分有效性主要与土壤有机质相关。This paper deals with the occupation of total volumetric capacity,water-holding capacity and transmission volumetric capacity of latored soils in low mountain,hills and platform in the south subtropics, discusses the differences in the occupying amount and occupying proportions of the available and unavailable water-holding capacity of the lated soils under different utilization patterns, and analyses the factors that control the water availability. Results show that the waterholding capacity, especially the available one,is less; and the water availability of the latored soils is affected by OM contrt particle composition and utilization patterns.
