【摘要】：由于城市中人口高度聚集,一旦发生灾害需疏散受灾居民到应急避难所中,因此应急避难所选址的合理性与适宜性就成为研究的重点。本文从经济性、效率性、公平性、安全性、可达性及环境因素等6个方面出发,选取12个应急避难所选址适宜性评价因子,并构建评价指标体系;利用TOPSIS评价方法构建适宜性评价模型,对研究区42处备选应急避难所的适宜性进行评价,结果表明:优秀级别8个、良好级别10个、中等级别23个、差等级别1个。研究结果可为应急管理部门在选择应急避难所建设位置时提供决策依据。
[Abstract]:Because of the high concentration of population in the city, once the disaster occurs, it is necessary to evacuate the affected residents to the emergency shelter, so the rationality and suitability of the location of the emergency shelter has become the focus of research. In this paper, 12 evaluation factors of location suitability of emergency shelter are selected from six aspects: economy, efficiency, fairness, security, accessibility and environmental factors, and the evaluation index system is constructed. The suitability evaluation model was constructed by TOPSIS evaluation method, and the suitability of 42 alternative emergency shelters in the study area was evaluated. The results showed that there were 8 excellent grades, 10 good grades, 23 middle grades and 1 poor grade. The results of the study can provide the decision-making basis for the emergency management department to choose the construction location of the emergency shelter.
