Urban park green spaces (UPGS) constitute a vital component of urban ecosystems, and the unequal distribution of UPGS can significantly impact the well-being of residents. Therefore, investigating the spatial delineation methods of UPGS service levels from the perspective of opportunity equity contributes to enhancing people's quality of life and promoting social harmony. Taking the Yingze District of Taiyuan City as an example, this study uses a modified accessibility measurement method of UPGS with the smallest clustered unit (building) as the service demand point and the UPGS entrance/exit as the service provision point, to establish a micro-scale evaluation framework for spatial equity considering the service radius and service quality of UPGS. The findings are as follows: after setting different service radius for UPGS at different levels, additional areas not covered by UPGS service were identified compared to setting the same service radius uniformly, which could prevent these areas from being overlooked in urban plans. After considering the quality of UPGS services, additional areas with low and high UPGS service levels were identified. Accurate spatial delineation of UPGS service level can avoid wasting public resources by including areas with high service levels in the scope of new UPGS requirements, while areas with low service levels lose opportunities for consideration in future urban infrastructure planning. This study emphasizes the residents' demand for both the quantity and quality of UPGS, facilitating an accurate assessment of whether urban residents can enjoy UPGS, the number of UPGS options available to them, and evaluate the quality of UPGS services experienced. Overall, this research provides new insights for evaluating the spatial equity of urban public facilities.
城市公园绿地（UPGS）是城市生态系统的重要组成部分，而 UPGS 的分配不均会对居民的幸福感产生重大影响。因此，从机会公平的角度研究 UPGS 服务水平的空间划定方法，有助于提高人们的生活质量，促进社会和谐。以太原市迎泽区为例，本研究采用改进的最小聚类单元（建筑物）作为服务需求点，UPGS 出入口作为服务供给点的 UPGS 可达性度量方法，建立了考虑 UPGS 服务半径和服务质量的微观尺度空间公平性评价框架。研究结果表明：在为不同水平的 UPGS 设置不同的服务半径后，与统一设置相同服务半径相比，会发现更多未被 UPGS 服务覆盖的区域，从而避免城市规划中忽略这些区域。在考虑 UPGS 服务质量后，会发现更多低服务水平和高服务水平的区域。准确划定 UPGS 服务水平可以避免在新的 UPGS 要求范围内包括高服务水平的区域，而低服务水平的区域在未来城市基础设施规划中失去考虑的机会。本研究强调了居民对 UPGS 数量和质量的需求，有助于准确评估城市居民是否能够享受到 UPGS、他们可选择的 UPGS 数量以及评估他们所体验到的 UPGS 服务质量。总的来说，这项研究为评估城市公共设施的空间公平性提供了新的视角。
