Abstract: As an essential part of environment equity, urban parks provide various benefits such as improving air quality, alleviating urban heat island effect, increasing entertainment opportunities, enhancing aesthetic value, promoting physical and mental health, preventing natural disasters, offering emergency shelters, etc. This paper provides a comprehensive evaluation of the equity of urban parks from the perspectives of accessibility of urban parks in terms of quality, quantity, square and time based on 9 311 residential communities in different traffic patterns. Social equity is discussed based on the Gini coefficient, Lorentz curve and location entropy. In a conclusion, the equity of urban parks in the northern part of Beijing is better than that in the south, and the west is better than the east, and an obvious circle structure is presented with the characteristics of "internally plane, centrally linear, and externally dotted". The areas with higher scores are mainly located within the Fourth Ring Road. The equity of public transportation in urban parks in high-density residential areas is relatively poor. The Gini coefficient of urban park resources in Beijing is 0.35, still imbalanced to some extent in allocation, but is better than that of other super large cities.
