Studies on design methodologies for nature restoration on collective housing sites in the metropolitan area of Japan

本研究的主要目的是探讨郊区丘陵地区新城发展的地貌转换过程，以及在其背景下的物理规划与设计的理念与理念。在仙里新城进行了一项案例研究，该研究覆盖了大阪府水田市和丰中市。根据图形图和项目报告中的信息，按照项目层面的三个步骤，即整个地区的项目规划、每个单独地区的规划和每个住宅区的布局设计，密切跟踪原始地形如何融入地貌和景观规划。虽然在项目规划层面上优先考虑地形地貌特征，并采用了许多将地形地貌应用于地貌设计的方法，但在项目后期，由于时间限制和土木工程…的创新，这些方法都被摒弃了更多的G技术。另一方面，在每个住宅区的开发层面上，通过结合地形特征来规划和设计突出的居住环境。本研究从(1)自然地形结构与土地利用模式之间的关系；(2)开放空间、行人通道及其网络系统的配置；(3)维持发达地区整体空间组织的几个值得注意的方面，对基于1965年提出并后来放弃的自然地形的多摩新市镇发展计划进行了研究。与已实现的发展计划的比较研究，需要更多的地貌改造，揭示了基于自然地形的计划的一些重要的当代意义如下。以山脊线和谷地为代表的丘陵地区自然地貌的最基本结构，用来勾勒出发达地区众多的土地利用单元，创造出具有丰富自然环境体验的开放空间和步行道网络，并作为实现居住区和其他设施优化组织的物理要素。从这个意义上说，该地区将为未来以自然环境基础设施为基础的恢复保留大量资源。较少

Primary purpose of this study was to examine the process of landform transformation for the new town development in the suburban hilly topographical areas, and the concepts and ideas of physical planning and design in its background as well. A case study was conducted in Senri New Town that extends across the area of Suita City and Toyonaka City, Osaka Prefecture. Based on the information found in graphical plans and project reports, and following three steps of project level, i.e. project planning for the entire area, planning of each individual area and layout design of each residential block, how the original topography was integrated into the landform and landscape planning was closely traced. Although the topographical features was given a higher priority on the level of project planning and numerous methods to adopt topography to landform design were employed, those have been dismissed in the later steps of project due mostly to time constrains and innovations in civil engineerin … More g technology. On the other hand, substantial endeavors were given to planning and designing prominent residential environment by integrating topographical features on the level of developing each residential block. Tama New Town Development Plan based upon the natural topography that was proposed in 1965 and abandoned afterwards was examined in this study in terms of (1)relationship between structure of the natural topography and land use pattern, (2)allocation of open space, pedestrian ways and their networking system, and (3)several noted aspects of functional system to sustain the overall space organization in the developed area. A comparative study with the realized development plan, which required higher amount of landform transformation, revealed some significant contemporary meanings of the plan based upon the natural topography as follows. The most basic structure of the natural topography in hilly area represented by ridgelines and valley areas was applied to articulate numerous land use units in the developed area, to create a network of open spaces and pedestrian ways rich in experience of natural environment, and to function as a physical elements that realize an optimum organization of residential districts and other facilities. In this sense, the area would have been preserving substantial resources for the future restoration based on the infrastructure of natural environment. Less
