Comprehensive Study of Exhibions and Methods of Instruction for Public Services such as Field Trips and Lectures Conceming an Interaction of Nature and Man Based on Geological Environments

本研究旨在以博索半岛南部米尼奥卡地区的地质环境为基础，构建关于自然与人的互动的实地考察和讲座等公共服务的展览和教学方法。许多山体滑坡分布在米尼奥卡地区的低起伏山坡上，霍塔群的页岩或砂岩在那里被剪切。这里的地貌过程与其他山区不同，在那里，正常的河流侵蚀要好于其他山区。由于滑坡的发育，地表地质、土壤、水、植被、土地利用等土地条件千变万化。在此基础上，建立了米尼奥卡区(等高线间隔10米)的详细地形地貌模型，从鸟瞰的角度展示了滑坡的分布规律和滑坡侵蚀的地貌形态。地貌模型图例如下：山体和丘陵主要受滑坡侵蚀(米尼奥卡山)滑坡区相对较新山脊和山顶缓坡以河流侵蚀为主的山体和丘陵侵蚀陡坡缓坡冲积冲积平原

This study is aiming at the construction of exhibitions and methods of instruction for public services such as field trips and lectures concerning an interaction of nature and man based on geological environments of the Mineoka district, south of the Boso peninsula.Many landslides are distributed on low-relief mountain slopes in the Mineoka district, where shale or sandstone of the Hota Groups have been sheared. The process of landforms there is different from another mountain area where normal river erosion is superior to. Also land conditions such as surface geology, soil, water, vegetation and land use are full of variety because of the development of landslide. So landslide areas are suitable for case studies of an interaction of nature and man.Then we produced some detailed relief models of geographical feature of the Mineoka district (10 meters contour interval) to show landslides distribution patterns and Jandforms eroded by landslide from a viewpoint of bird's eyes. And we also made some exhibits which showed landform process of landslide area or interactions of landslide distribution and geology, water, land use etc., comparing with the surrounding mountains and hills.The legend of the landform classification map of the relief models is as follows;Mountain and hill mainly eroded by landslide (The Mineoka mountain)Landslide area comparatively newerodedRidge and peakHillside gentle slopeMountain and hill mainly eroded by river (The Kazusa and the Awa hills)Eroded steep slopeEroded gentle slopeAlluvial coneAlluvial plain
