Abstract: The reasonable accessibility of the distribution of fire station is of great significance for preventing and resolving the hidden dangers to urban safety. Traditional fire station distribution rarely considers residents' fire resource demand, resulting in structural problems caused by mismatching supply and demand. This paper improves the traditional site selection model from the aspects of supply and demand. In terms of supply, the best explanatory variable combination and its weight for fire occurrence are determined through exploratory analysis and generalized linear regression, so as to accurately assess the regional fire risk, and the reasonably determine the proposed location of the fire station. In terms of demand, by introducing an accessibility factor to increase the consideration of the location model for residents' demand for fire station. Then take Huizhou as an example to carry out the research on location optimization of the fire station, and verify the optimization effect of the improved location strategy by designing two other location strategies, so as to verify the effectiveness of the text improvement model.

Key words: fire station accessibility, site allocation strategy, fire location distribution, fire risk assessment
