Relationships between vegetation units of secondary forests of Quercus serrata and soil conditions were studied in Tokorozawa city, central Honshu, Japan. The forests were classified into 2 associations of Quercetum acutissimo-serratae, including 2 subassociations, and Castaneo-Quercetum serratae, with 2 subassociations and 4 variants. The soils of Quercetum acutissimoserratae were mainly Andosols, and those of Castaneo-Quercetum serratae, Brown forest soils. Clear differences in soil conditions were detected between the typical subassociation of Quercetum acutissimo-serratae and the variant of Acer crataegifolium of the typical subassociation of Castaneo-Quercetum serratae, these being integral parts of each association. Major differences were evident in depth of A horizon, pH and porosity. It was ascertained that Quercetum actissimo-serratae was distributed on soils with a deeper A horizon, higher humus content and higher pH values and porosity percentages than Castaneo-Quercetum serratae. These results suggest that such pedological physicochemical properties contribute to the differentiation of these associations in the secondary forests of Quercus serrata.
