| Research Abstract |
In this study we present the preliminary results about the analysis of theδ18Ｏof phytoliths from living leaves of Japanese Sasa and Phyllostachys toward the future paleoenvironmental reconstruction. The relationship between the δ18Ｏ value of the sample and estimated mean annual temperature at the sampling site indicates weak positive correlation as a whole and it seems to be also affected by latitude, altitude and distance from coast. More data and further statistics research are needed to clarify the implication of the relationship between environmental factors and theδ18Ｏ value of phytoliths from Japanese Sasa and Phyllostachys.
