| 公园绿地是城市建成环境和综合生态系统的重要组成部分，研究公园绿地的空间分布和分配均等化水平对公园布局规划工作具有重要的指导意义。以广州市南沙区为例，利用融合了多种出行模式、多级时间阈值及高斯函数的改进型两步移动搜索法，分析南沙区各类型公园绿地可达性空间格局，并在全区综合可达性结果的基础上进行空间自相关分析和公园绿地资源分配公平性探究。结果表明，南沙区不同规模公园的可达性具有差异化的空间格局，其中生态公园和城市公园的整体可达性值高且高值区域存在空间集聚现象，而社区公园和游园因服务范围较小使得整体可达性值较低且空间差异较大；南沙区所有类型公园的综合可达性存在“西北部低、东南部高”的分布格局，空间集聚特征显著；在基于基尼系数的公园绿地公平性测度中，有4个街镇达到高度平均分配水平，3个街镇达到分配相对平均水平，东涌镇基尼系数值最高，但其分配也属于相对合理水平。 |

| Park green space is an important part of the urban built environment and integrated ecosystem. Studying the spatial distribution and equalization level of park green space plays an important guiding role in park layout planning. Taking Nansha District of Guangzhou City as an example, this paper used an improved two-step floating catchment area method that integrated various travel modes, multi-level time thresholds and Gaussian functions to analyze the spatial pattern of accessibility of various types of park green space in Nansha District. Based on the comprehensive accessibility results, analysis of spatial autocorrelation and exploration of the equity of park green space resource allocation were carried out. The results showed that the accessibility of parks of different scales in Nansha District had a differentiated spatial pattern, among which, ecological parks and urban parks had high overall accessibility values and high-value areas had spatial agglomeration, while community parks and pocket parks had smaller service ranges, which made the overall accessibility values were low and spatial variance was high; the comprehensive accessibility of all types of parks in Nansha District had a distribution pattern of “low in the northwest and high in the southeast”, with significant spatial agglomeration characteristics; in the equity measurement of park green space based on Gini coefficient, four streets (towns) reached highly evenly distributed levels, and three streets (towns) reached relatively evenly distributed levels, and Dongchong Town had the highest Gini coefficient value, but its distribution was also at a relatively reasonable level. |
