- Abstract:
- In order to improve the accuracy of pre-earthquake disaster risk assessment and estimate the population spatial distribution in post-earthquake disaster rapid assessment,based on the population data of villages and towns surveyed in Sichuan Baoxing County in 2016 and the building data in Tianditu,we use the method of population density of residential buildings to obtain the vector data of population distribution at the scale of residential buildings in villages and towns of Baoxing County,and verify the accuracy of the actual population of individual building through field investigation. The experimental results show that taking the volume of residential buildings as the indicator of population spatial distribution,the fitting accuracy is 0.902 7,and the average relative error of population is 15.23%,which provides more reliable data support for pre-earthquake disaster risk assessment and post-earthquake disaster rapid assessment.
