| Research Abstract |
Based on the knowledge that oxygen and hydrogen isotope ratios in tree-ring cellulose can record past changes in precipitation and relative humidity in yearly and seasonal time resolutions, variations in water cycles at many areas from Hokkaido to Southwest islands in Japan were reconstructed during last several hundreds or a few thousands years and analyzed for their climatological, historical and ecological implications, such as long-term changes in Baiu-ENSO relationship, impact of flood and drought cycles on Japanese history and long-term response of vegetation to global warming.
