摘要
基于地理国情市情普查监测成果数据,采用时空变化监测分析方法,从地理空间层面对城市韧性进行评估,为韧性城市的建设提供技术和数据支撑。首先,研究了多源异构时空地理数据大融合,建立了城市空间韧性数据库;然后,综合运用GIS技术、DSM差分技术、遥感影像识别等先进技术,从空间维度和时间维度进行了城市基础韧性研究;最后,以城市高危仓储分布和监测方法为例,进行了城市韧性专项监测研究。综上,本文所述方法将大幅度提升地理信息数据服务韧性城市建设的能力。
Based on the achievements of the geographical conditions census,this paper adopts a method of spatial-temporal change monitoring to evaluate urban resiliences and provides technical support for the construction of resilient urban. Firstly,this paper studies the integration of multi-source heterogeneous spatial-temporal geographic data,and establishes resilience database of urban space. Then,using the advanced technologies such as GIS,DSM and remote sensing image recognition,the basic urban resilience is studied from space dimension and time dimension. And then,the urban high-risk storage distribution and monitoring methods are taken as an example to monitor the urban resilience in special area. Finally,from the time dimension,the change monitoring of urban resilience is studied. In conclusion,the method described in this paper will greatly enhance the ability of geographic information to resilience urban construction.
