【摘要】 基于36个中国主要城市的4万余个公园绿地、9万余个居住区及200余万人口空间分布大数据，构建公园分布均好度评价模型；持续4年对36个中国主要城市公园空间分布情况进行跟踪评估。结果表明：1)2021—2024年全国公园分布均好度平均值从1.54提升至1.59，增幅达0.05;2)不同规模城市呈现差异化增长趋势，特大城市与Ⅰ型大城市增速加快，Ⅱ型大城市增速放缓，超大城市则出现小幅波动；3)从公园类型看，游园(口袋公园)服务覆盖率4年增长近2%，显著高于综合公园(1.7%)和社区公园(0.5%);4)城市更新背景下中小规模公园建设对优化空间均衡性具有关键作用，南昌、合肥等城市通过高密度游园布局实现公园分布均好度跨越式提升。更多还原

【Abstract】 This study is based on big data on the spatial distribution of over 40,000 parks and green spaces, over 90,000 residential areas, and over 2 million people in 36 major cities in China, and constructs an evaluation model for the average distribution of parks. It tracked and evaluated the spatial distribution of parks in 36 major Chinese cities over a period of 4 years. The study found that the average distribution of parks in China increased from 1.54 to 1.59 between 2021 and 2024, with an increase of 0.05. Different-sized cities show differentiated growth trends: the growth rate of mega cities and Type Ⅰ cities accelerates, while that of Type Ⅱ cities slows down, and there are slight fluctuations in mega cities. From the perspective of park types, the service coverage rate of amusement parks(pocket parks) has increased by nearly 2% in the past four years, significantly higher than that of comprehensive parks(1.7%) and community parks(0.5%). Research has shown that the construction of small and medium-sized parks plays a crucial role in optimizing spatial balance in the context of urban renewal. Cities such as Nanchang and Hefei have achieved a leapfrog improvement in overall quality through high-density park layouts.更多还原
