摘要:
在快速城市化和地震灾害频发的背 景下,绿地系统的防灾避难功能得到极大重 视。高校是城市中人口密集区域之一,又是国 家人才的集中地,高校绿地系统应急避难机 能的研究就显得尤为重要。该研究对福州大 学绿地系统应急避难的机能进行分析,首先 调查并统计整理了福州大学旗山校区的各项 基本数据;其次运用ArcGIS的空间技术分析 手段,分别以服务半径300 m、500 m计算缓 冲区所覆盖面积;最后对绿地系统进行可达 性分析。通过分析得出结论:福州大学绿地 避难系统基本满足紧急、固定的避难场所要 求,但生活区和教学区人均避难面积相对较 低;可达性方面教学区最弱,运动区最好。通 过得出的结论,为提高该校园应急避难能力 提出建议。

Research on Emergency Shelters Capacity of Urban Green Space System Based on GIS

Abstract:
Under the context of rapid urbanization and frequent earthquake disaster, the disaster prevention and sanitation function of the green space system has been greatly paid great attention to. Colleges and universities are one of the most densly populated areas in the city, and it is the focus of the national talent. Hence, it’s particularly important to conduct studies on the emergency shelters capacity of the green space system. This paper analyzes the function of shelters of green space system in Fuzhou University. Firstly, it investigates and summarizes the basic data of Qingshan campus in Fuzhou University. Secondly, using ArcGIS’s spatial technology analysis method, the coverage area of the buffer is calculated by using the service radius of 300 m and 500 m respectively. Finally, the reachability of the green space system is analyzed. Through the analysis, it’s concluded that Fuzhou University green shelter system basically meet the urgent and fixed evacuation sites, but the living area and teaching area per capita asylum area is relatively low, and the accessibility of the teaching area is the weakest, and sports area is the best. It’s expected that it will provide suggestions for improving the campus emergency shelter capacity.
