A study on urban disaster risk evaluation and mitigation in an aged society using spatial temporal geographic information

在坂神淡路大地震前后，穿过京都市区的花入、西山、小备断层活动，因此有必要对京都市区的巨大灾害采取行动。这个地区有很多传统的木制房屋和死胡同，因此很容易受到灾害的影响。但是，我们不能仅仅为了防止灾难的破坏而改变城市景观，因为它是日本的文化资产之一。此外，大多数住在那里的人都希望在他们的生活中继续住在同一个地方，但他们太老了，也没有那么富有，他们无法自己修复他们的生活环境。因此，我们必须考虑在这些地区发生灾害后的风险缓解计划。在此计划中，有必要将老年人视为风险承担者，因为他们大多数在日常生活中有身体障碍，在灾难中无法避免许多困难。本研究的目的是在tta中表示一个巨大的灾难风险准备金， 关于我们 首先提出了以城市景观为基础的脆弱区指数，并将脆弱区划分为目标区域;其次，对京都市城区滨水历史变迁进行了说明，以检查作为滨水创造潜力的丧失滨水，从而减轻地震灾害风险。特别是我们考虑了堀川川滨水开发计划，作为减轻地震灾害风险的滨水再生的实施。通过对目标区老年人的访谈调查分析，了解了目标区社区的失活状况。再次，在原有调查问卷的基础上，提出了老年人的生活方式模式，并对老年人风险缓释社区建设进行了探讨。社区分为居住点型社区和设施型社区两种类型。然后我们解释了这两个社区是互补的。但在传统的研究中，仅仅指出了前社区的重要性。最后，提出了基于社区活动的提高区域防灾能力的途径之一，以实现滨水自然开放空间所具有的减灾功能，因为规划滨水自然开放空间具有减灾功能，需要激活区域社区。少

About the time at Hanshin-Awaji Earthquake, the Hanaore, Nishiyama, and Obaku fault that pass through urban area in Kyoto city have been activate, so it is necessary to act against the huge disaster in the urban area, Kyoto city. This area has a lot of traditional wooden houses and dead-end street, so it is vulnerable for the disaster. But we can't change the townscape only to prevent damage in a disaster because it is one of the cultural assets in Japan. Furthermore most of people living there hope to keep on living the same place in their lives, but they are so old and not so rich that they can't repair their living environment themselves. Therefore we have to consider risk mitigation plans after a disaster in these areas. In this plan, it is essential to regard aged people as exposures, because most of them have physical handicaps in daily life, and cannot avoid many difficulties in a disaster.In this study, our purpose is to denote a provision against a huge disaster risk in the ta … More rget area.Firstly we have suggested the vulnerable area index based on the townscape and show the vulnerable area in the target area.Secondly we have explained waterside historical transition in urban area, Kyoto city, in order to check the lost watersides which are the potential of water side creation for mitigation of earthquake disaster risk. Especially we have considered Horikawa River Waterside Development Plan as an implementation of waterside reborn for earthquake disaster risk mitigation. Through the analysis of interview survey intended for senior person living in the target area, we knew inactivation of the community of target area.Thirdly we have denoted a pattern of life style of aged people based on our original questionnaire and discussed the construction of community for risk mitigation of aged person. Community has been classified into two types : inhabit point based community and facility based community. And then we have explained that both communities are complementary. But in traditional research, the importance of former community was only pointed out. So we focused the importance of latter one and their complementary relationship.Finally, we have suggested one of the way to increase regional disaster prevention capacity based on community activity to implement disaster mitigation functions which waterside natural open-spaces have, because it is necessary to activate regional community for planned waterside which function as the disaster risk mitigation.
