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

在阪神-浅地地震发生的时候，经过京都市区的花原、西山、大盆断层已经被激活，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房子和死胡同，所以很容易受到灾害的影响。但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，大多数生活在那里的人希望在他们的生活中继续生活在同一个地方，但是他们太老了，也不那么富有，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。在这个计划中，必须将老年人视为暴露者，因为他们中的大多数人在日常生活中都有身体残疾，在灾难中无法避免许多困难。在本研究中，我们的目的是表示一个针对巨大灾害风险的拨备。首先，我们提出了基于城镇景观的脆弱区指数，并在目标区域内显示脆弱区。其次，我们解释了京都市区水边的历史变迁，以检查失去的水边，这是水边创造的潜力，以减轻地震灾害风险。特别是我们将《堀川河水边开发计划》视为一种“水边重生”的实施，以减轻地震灾害风险。通过对目标区老年人访谈调查的分析，了解目标区社区的失活情况。第三，我们在原始调查问卷的基础上提出了老年人的生活方式模式，并探讨了老年人风险缓解社区的建设。社区分为两种类型：居住点型社区和设施型社区。然后我们解释了这两个群体是互补的。但在传统研究中，只是指出了前社区的重要性。因此，我们关注了后者的重要性以及它们之间的互补关系。最后，我们提出了一种基于社区活动来增强区域防灾能力的方法，以实现滨水自然开放空间所具有的减灾功能，因为必须激活区域社区，以规划滨水作为减灾功能。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.
