日本密集市街地更新中灾害韧性提升的经验与启示

Experience and Enlightenment of Disaster Resilience Improvement in High-density Urban Renewal in Japan

城市高密度老旧城区具有较高的应灾脆弱性,需要通过城市更新进行局部空间整治以提升其灾害韧性。针对高密度老旧城区更新中改造空间不足、居民意愿低下等常见问题,从法规引导下的安全底线保障、全方位的项目补贴激励两方面出发,分析日本密集市街地更新中的应对方法,并总结在城市更新背景下日本区内停留地区制度对于高密度城区避难空间规划的应用价值,最后为我国高密度老旧城区更新和韧性提升提出相应建议。

High-density old urban areas are more vulnerable to disaster damage,and local spatial remediation through urban renewal can significantly improve disaster resilience.Aiming at the common problems such as insufficient renovation space and low residents'willingness in the renewal of high-density old urban areas,this paper introduces the solutions to the renewal of Japan's high-density urban areas from two aspects:the bottom line of safety under the guidance of regulations and all-round project subsidy incentives,then analyzes the role of Japan's stay area system in the planning of shelter space in high-density urban areas under the background of urban renewal,and finally puts forward corresponding suggestions for the renewal and resilience improvement of high-density old urban areas in China.
