城市片区空间避难疏散适宜性评价及相关性分析
Spatial Suitability Assessment and Correlation Analysis of Evacuation in Urban Areas
摘要
Abstract
To optimize the shelter and evacuation space in urban areas and improve the emergency management level of the areas,taking the central urban area of a certain city as the research region,an evaluation system for the suitability of shelter and evacuation with"disaster prevention areas"as the object was constructed.And based on spatial statistical methods such as Moran's Index and Gini Coefficient,the spatial characteristics were analyzed to explore the rationality of the spatial distribution of shelters in the areas from the dual perspectives of suitability and spatial attributes.The research results show that there is a certain correlation between the suitability of shelter and evacuation in the urban areas and the compactness and fractal dimension of the areas.The shelter and evacuation facilities and environment can be further improved according to the spatial characteristics of the areas.There are significant differences in shelter and evacuation among the first-level areas,while the differences in the suitability of shelter and evacuation among the second-level disaster prevention areas within them are relatively small.To improve the suitability of shelters in the areas,multiple influencing factors need to be comprehensively considered.关键词
