Abstract:

Abstract: Based on the needs of urban fire station layout assessment, a regional fire risk assessment index system including four indicators, land use type, population density, floor area ratio, and average number of floors was established. And the index score assignment method, regional fire risk calculation method and regional fire risk classification basis were given as well. Based on the results of regional fire risk assessment, fire response standards under different fire risk levels were proposed, and fire station layout assessment methods based on three indicators: fire station response coverage rate, fire station cross response coverage rate and fire station average response time were established. The detailed calculation method of each index and the evaluation standard of urban fire station layout performance were given. Taking a city in North China as an example, the regional fire risk assessment technology and urban fire station layout and optimization technology based on fire risk were verified. 

Key words:  fire risk, fire station layout assessment, network analysis
