abstract="In order to enhance the ability of urban disaster prevention and mitigation, improve success rate of resident refuge, and reduce irrational use of emergency shelter facilities and waste of resources during a disaster, a model of service scope division was put forward which was aiming at problem of high overlap and unreasonable results in current division of shelters. Firstly, the influence of actual road network and other factors were taken into consideration, and the set of influencing factors and evaluation index system of service ability were constructed, including four first-level indicators: accessibility, rescue balance, selectivity and security, and 16 second-level indicators. Then based on actual road network, the space syntax model and spatial and network analysis tools of ArcGIS were used to calculate data of each indicator. And the comprehensive value of service ability was calculate by the gray comprehensive correlation model. Finally, weighted Voronoi diagram was used to divide service scope of emergency shelter, and the proposed method was applied to the emergency shelters in Haidian District of Beijing to verify its validity. The results show that compared with traditional partition model, the method considers influence of other factors on service scope and can reasonably define service scope of the shelter. © 2019 China Safety Science Journal<p /><p>Language: zh</p>",
