Abstract
The study aims to understand chemical characteristics of soil solution and spring water on different vegetation management regimes in secondary woodlands of Tama Hills, central Japan. Soil samples were collected at different vegetation management regimes and EC, pH and ion concentration in dissolved water were measured. In results, management types determined the soil chemical characteristics. Ion concentration of Ca2+, Mg2+, and NO3- was significantly lowest at the surface of moved and fallen-leaf-rid sites and highest at those of abandoned. Soil solutions were collected at different micro-scale landforms in a neglected watershed and a managed one. At crest slopes and head hollow, accumulation of EC, Ca2+, and NO3- was significantly higher in the neglected watershed than in the managed watershed. The similar trend was also found in subsurface soil solutions. At valley bottom, however, NO3- concentration declined remarkably, and then it was few in spring water of both watersheds. On the contrary, Na+ and Ca2+, concentrations were increased. Therefore, there was no management effect on chemical characteristics of spring water. This implied denitrification and mineral elution from geological formation could characterize ion components of spring water at an ordinary water-stage.
