| Research Abstract |
This study aimed to clarify the physiographical constraints of alpine landslides on landscape evolution during the deglacial and interglacial periods in the Japanese Alps, from the perspectives of historical geomorphology and Quaternary science as well as plant ecology and paleoecology. In Mount Shiroumadake, Mount Eboshi-dake, Mount Asahi-dake and Mount Chogatake of the northern Japanese Alps, geomorphic features of landslide complexes and gravitational mass rock deformation have affected the development of alpine plant community. In Mount Suishodake of northern Japanese Alps, the early Holocene large landslides effected the formation of bogs, wet meadows and patchy forest of conifers. Geospatial analysis using GIS, DEM, RS and digital data of regional geology clarified that formation and development of alpine lakes and ponds have also been influenced by landslide topographies such as antiscarps, linear depressions and low relief mounds.
