摘要

Although urban green space (UGS) is an important factor in improving the well-being of residents, the problem of green injustice has been proven to be prevalent. Balancing the quantity distribution of UGS is an important way to solve the problem, but the effect is declining owing to many reasons. The general lack of evaluation of UGS quality in accessibility model leads to the insufficient understanding of real inequality and the inability to excavate strategies from the level of quality. Accordingly, this article first established an evaluation system for the serviceability of UGS (including size, outerconnectivity, inner-connectivity, diversity, eco-serviceability, and compactness). Based on the comprehensive floating catchment area method, the spatial distribution patterns and inequality differences of UGS quantity and quality accessibility under three traffic modes are compared. The results show that evaluating the quantity inequality of UGS may lead to overestimation of real inequality, and other functional advantages can offset the quantitative disadvantages. The government-led quality improvement intervention and the policy of enhancing residents' transportation capacity can alleviate green inequality. The finding confirms the significance of serviceability in improving green equity and provides guidance for government leaders and researchers on the development of UGS in the future.
