Abstract

Urban green space equity is a crucial component of achieving urban fairness. This study quantitatively assesses the equity of green space usage in urban villages compared to formal residential communities, focusing on the living spaces of vulnerable groups.

To accomplish this, green space area data, FVC, and NDVI data were utilized to analyze green space conditions in various residential areas of central Beijing. Subsequently, statistical methods, including the Gini index and Theil index, were employed to evaluate the equity of vegetation coverage, vegetation condition, per capita green space, and accessibility.

Our findings indicate that the equity of per capita green space is lower in both urban villages and residential communities across varying distances. However, the assessment results for FVC and NDVI present contrasting outcomes, with slight differences in their equity results.

This study offers valuable recommendations for policymakers to prioritize the enhancement of green space equity in specific residential areas by analyzing the availability of green spaces, as well as the equity of FVC and NDVI in different residential types. Additionally, we propose a pragmatic and effective approach to advancing green space equity in medium and large cities.
