内容 研究概要:The suburbs of Tokyo Metropolitan area has been experiencing heavy land use/cover changes followed by modernization of Japan. The stages of land surface alteration can be precisely monitored by satellite remote sensing data and printed maps. Image processing system and Geographic Information System are used to draw land use/cover maps, and the changes in it was discussed. After delineating the urbanization process, the changes in hydrological cycle are assessed. In this paper, changes in areal evapotranspiration due to urbanization and the response of groundwater flow system for changing recharge are evaluated. As a result, decrease in evapotranspiration is assessed quantitatively, and it is clarified that the effect of decreasing recharge is large in local ground water system in upper stream. Finally, addition of runoff component was discussed. Although, the synthesized basin hydrological model is remained as future objectives, its completion is necessary to get a true prospect of future environments by assessing the consequence of the impact to ground surface by man's activity.
