Study on effects of alpine landslides during deglacial and interglacial periods on landscape evolution in the Japanese Alps

本研究旨在从历史地貌学和第四纪科学以及植物生态学和古生态学的角度，阐明日本阿尔卑斯山冰川消退期和间冰期期间高山滑坡对景观演变的自然约束。在日本阿尔卑斯山北方的白岳山、江保岳山、旭岳山和长岳山，滑坡复合体的地貌特征和重力块体岩石变形影响了高山植物群落的发育。在日本阿尔卑斯山北方的水照岳，全新世早期的大型滑坡影响了沼泽、湿草甸和零星针叶林的形成。利用GIS、DEM、RS和区域地质数字数据进行的空间分析表明，高山湖泊和池塘的形成和发展也受到反陡坎、线性洼地和低起伏土丘等滑坡地形的影响。

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.
