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

这项研究的目的是为公共服务建设展览和教学方法，如实地考察和讲座，以博索半岛南部米尼奥卡地区的地质环境为基础，介绍自然与人的相互作用。许多滑坡分布在米尼奥卡地区的低起伏山坡上，在那里Hota组的页岩或砂岩被剪切。这里的地貌过程不同于其他以正常河流侵蚀为主的山区。由于滑坡的发展，地表地质、土壤、水、植被、土地利用等土地条件也发生了变化。因此，滑坡区适合作为自然与人类相互作用的案例研究。在此基础上，以10米等高线间距制作了详细的地形模型，从鸟瞰的角度展示了山体滑坡的分布格局和滑坡侵蚀的地貌。我们还制作了一些展览，展示了滑坡区的地貌过程或滑坡分布与地质、水、土地利用等的相互作用，并与周围的山脉和丘陵进行了比较。地形模型地貌分类图图例如下：以滑坡侵蚀为主的山地（米诺冈山）滑坡区相对较新山岭峰山坡缓坡以河流侵蚀为主的山地（喀萨山和阿瓦山）侵蚀陡坡侵蚀缓坡冲积平原

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
