基于人群分布的高密度老城区避灾空间优化——以重庆渝中半岛为例

Research on Optimization of Disaster-prevention Space of High-density Old City Based on Crowd Activity Distribution:A Case Study of Yuzhong Peninsula of Chongqing

城市避灾空间是城市安全的基础保障,也是韧性城市建设的空间前提。文章通过对重庆渝中半岛高密度老城区避灾空间进行调查分析,提取避灾空间地形环境、空间容量、入口数量等信息数据,分析避灾空间的总体质量;从静态功能与动态活动相结合的角度,对该区域的人群特征进行研究,发现渝中半岛人群活动的4个特征;最后提出高密度老城区避灾空间优化路径思考,希望为我国正在进行的高密度老城区存量空间高质量发展提供参考,为韧性城市建设提供支撑。

This study firstly conducts an investigation in the public space of a high-density old area in Yuzhong peninsula to analyze terrain environment,space capacity and the number of entrance of disaster-prevention space and estimates the overall quality of disaster prevention space.Secondly,the flow characteristics of these area are identified from the perspectives of both the static and the dynamic.Finally,based on the case study in Yuzhong peninsula,this study proposes optimized paths for disaster-prevention space in high-density old city,which provides a reference for high-quality development of the old town stock space and construction of resilient cities in China.
