摘　　要：本文采取点面结合 ,运用区域对比方法 ,剖析了福建赤红壤、红壤旱地土壤水总库容、贮水库容、有效水库容和通透库容的差异 。Based on investigation and laboratory analysis of several representative dryland soil pedons in Zhanpu and Jianou, we investigated soil water total volumetric capacity, water-storage volumetric capacity and available water-storage capacity in the lateritic red earth (Typic Rhodudalfs in Soil Taxonomy) and red earth (Humic Hapludults in Soil Taxonomy) dryland. The total volumetric capacity and water-storage volumetric capacity of the lateritic red earth dryland soil is smaller than that of red earth dryland soil. The available water-storage volumetric capacity of the lateritic red earth and red earth dryland in Fujian province were both smaller, only 70mm in 1m solum, which did not reach one third of that of the chernozem in North-East of China and that of chao soil (Ochrepts in Soil Taxonomy) in North China when they are in the same thickness of the solum. At last, some existing water problems were analysed in this paper.
