The distribution pattern of these soil types closely follows human activity and climate. The Aqualfs are considered to be transformed from Ultisols by human activities. , Ca, K) adsorbed on the surfaces of soil particles, so that the increase of base saturation results in the soils to become Alﬁsols (Hseu and Chen 1996). Taiwan is a humid and tropical/subtropical country, but the unique difference between the Udalfs and Ustalfs is soil moisture regime depending on local strength of seasonal monsoon from China.
In the sediment basin between exposed coral reefs, Alﬁsols are commonly found in the reserve. Field morphology of the CR3 pedon is described as follows (Fig. 8). If not otherwise indicated, soil color is given for moist soil. The surface soil textures of the four habitats are clayey textured with >40 % clay. 0 cmol/kg). 5). 5YR 4/4) clay; strong medium and coarse angular blocky structures; clear continuous clay coatings on the pedsurfaces (Fig. 13 Mg/ha/year, and thus was in the higher order of the range for humid tropical forests (Liao et al.
Tsai et al. (2008) used three pedons of alluviumrelated red soils were sampled from the Taoyang (TY-YM), Pakua (PK-1), and Chiayi terraces (CY-1), respectively located in northern, central, and southern Taiwan. Meteoric 10 Be dating shows ages of ≥261 ka for TY-YM, ≥124 ka for PK-1, and ≥386 ka for CY-1. However, the trend of these ages does not agree with the degree of soil development. The former two ages are likely underestimated through loss of 10 Be due to strong leaching and considerable erosion.
