The reasonable planning of emergency shelter in urban communities is one of the important means of disaster prevention. Using the improved Two-Step floating catchment area method and GIS, this paper analyzes the accessibility of emergency shelter in Yuexiu district under microcosmic perspective. The conclusions are as follows: Firstly, the total amount and type of emergency shelter are abundant in Yuexiu district, per capita emergency shelter is high, but spatial distribution is unreasonable; Secondly, the overall accessibility of emergency shelter is poor, north region better than south region, and supply and demand ratio is an important factor about the difference of accessibility; Thirdly, when d0 to 1500m, emergency shelter accessibility reaches the maximum and proportion of service area is the best. The related conclusions can provide some reference for the optimization and planning of emergency shelter in Yuexiu district.
