Abstract: Spatial equity of parks is a major concern in environmental justice studies. While many measurements have been used to evaluate access to parks, few studies have considered the impact of travel behavior on park accessibility. This study aims to establish a travel behavior-based Gaussian two-step floating catchment area (TB-G2SFCA) method to assess spatial equity of parks in the Nanjing region, and Local Moran's I index is applied to identify spatial agglomeration patterns in assessing equity. The results demonstrate that (1) the traditional single-mode model maybe cannot provide accurate approach to evaluating park accessibility while the TB-G2SFCA method can provide a more realistic park accessibility evaluation; (2) the inhabitants of most communities distributed south of the Yangtze River can obtain better park services than the northern areas; (3) the spatial disparities of equity in park accessibility are severe in three suburban districts, relatively minor in four central districts, and insignificant in two central districts. These findings may assist urban planners and policy makers to frame more reasonable policy and planning to improve spatial equity to parks in urban areas.
