Urban green spaces (UGS) can counter the ill effects of urbanization in high-density cities. Studies related to these aspects are rare in Indian cities, however. This article aims to assess the availability and accessibility of UGS in Raipur, India. The objectives are to identify the status of UGS alteration, determine the status of available UGS, and identify the optimum population density for which UGS can be made available and accessible. Land use change detection, fragmentation index, availability index, UGS per capita, and neighborhood accessibility are used to assess aspects of UGS. The results show an increase in built-up area (24.32 percent) from 2010 to 2020. They also show a decrease in the UGS availability index and an increase in the fragmentation index from the city center to the outskirts. Uneven distribution of UGS categories is found all over the studied urban area. Low-density areas have more UGS per capita available than high-density areas, whereas medium-high-density areas have the maximum UGS accessibility. The study concludes with density-wise implications to maximize the UGS benefits and identifies medium-high density as the optimum density that allows high accessibility to the available UGS.

城市绿地 (UGS) 可以对抗高密度城市城市化的不良影响。然而，与这些方面相关的研究在印度城市中很少见。本文旨在评估印度赖布尔的 UGS 的可用性和可访问性。目标是确定 UGS 变更的状态，确定可用的 UGS 的状态，并确定可以提供和访问 UGS 的最佳人口密度。土地利用变化检测、碎片化指数、可用性指数、人均 UGS 和邻里可达性用于评估 UGS 的各个方面。结果显示，从 2010 年到 2020 年，建成区面积增加（24.32%）。它们还显示 UGS 可用性指数下降，从市中心到郊区的碎片化指数增加。在所研究的城市地区，UGS 类别分布不均。低密度地区的人均可用UGS比高密度地区多，而中高密度地区的UGS可达性最大。该研究总结了密度方面的意义，以最大限度地提高 UGS 的效益，并将中高密度确定为允许对可用的 UGS 进行高度访问的最佳密度。
