The accessibility of green space is an important factor affecting urban ecological resilience. Improving the accessibility of green space and optimizing its layout can effectively enhance urban ecological resilience. Taking Busan as an example, this paper uses Gaussian Two-step floating catchment area method (Ga2SFCA) to evaluate green space accessibility. The Getis-Ord   method is used to identify significant hot spots and cold spots of green space accessibility, conduct hot spot analysis, and analyze its spatial agglomeration characteristics. The results show that the overall green space accessibility shows a basic trend of decreasing from both sides to the middle. There are significant differences in accessibility between different administrative regions, and the spatial distribution of green space resources is uneven. There is an imbalance between population density and green space supply and demand. The spatial agglomeration characteristics of green space accessibility are significant and clearly layered. This paper can accurately identify resource shortage or surplus areas in the city and areas that need priority improvement by comprehensively analyzing accessibility, hot and cold spots, and population density, providing strong support for balancing the supply and demand of green space resources and improving the quality of urban ecological resilience.
