| 摘 要： | 避难场所的规划选址与开敞空间的避难容灾能力密切相关,但较少研究关注到人口分布现状对避难场所空间选址的影响。以深圳市南山区为例,采用遥感及GIS技术,结合社区人口统计数据,通过分析区内开敞空间的有效性、安全性、通达性及收容性,综合评价其避难容灾能力,为城市避难场所选址筛选出适宜的空间。结果表明:量化的评价程序可有效地剔除有安全隐患或通达性较差、容灾能力不足的空间,结合人口分布现状更能凸显区域内避难场所空间分布的不足,容灾缺口计算结果可作为城市避难场所增设选址的参考依据。

| Abstract: | Planning and locating disaster shelters directly influences the evacuation capability of urban open spaces.However,few researches paid attention to the influence of population distribution on urban shelters location.As a case study in Nanshan District,Shenzhen,the effectiveness,safety,accessibility and accommodation of all open spaces were analyzed through remote sensing,GIS,and community demographic data.Appropriate places were selected for the city shelters.Results show that: quantitative evaluation proce... |
