摘　　要：公园绿地的可达性对居民生活和城市规划具有重要意义。针对现有研究对可达性计算过程中的供给能力影响因素考虑单一的问题,该研究以荆州市中心城区为例,综合考虑主观因素和客观因素对可达性的影响,基于公园绿地面积、植被覆盖度、分形维数、边缘密度和百度评分等数据,运用改进两步移动搜索法测度街道尺度下公园绿地可达性,并采用Moran's I等方法分析其空间聚集模式。研究结果显示,荆州市中心城区公园绿地可达性存在明显的空间差异,中部区域可达性较高,边缘区域较低,且整体呈现出较强的空间集聚性。该研究为荆州市优化公园绿地资源配置和城市规划提供科学依据,也可为其他类似地理现象的可达性研究提供参考。The accessibility of park green spaces is of great significance to residents'lives and urban planning.In view of the problem that existing research considers a single factor affecting supply capacity in the calculation of accessibility,this study takes the central Urban area of Jingzhou City as an example to comprehensively consider the impact of subjective and objective factors on accessibility.Based on data such as park and green space,vegetation coverage,fractal dimension,edge density and Baidu score,the improved two-step mobile search method is used to measure the accessibility of park green spaces at the street scale.,and Moran's I and other methods are used to analyze its spatial aggregation pattern.The research results show that there are obvious spatial differences in the accessibility of park green spaces in the central Urban area of Jingzhou City.The accessibility is high in the central area and low in the marginal areas,and the overall situation shows strong spatial agglomeration.This study provides a scientific basis for Jingzhou City to optimize the allocation of park and green space resources and urban planning,and can also provide a reference for accessibility research of other similar geographical phenomena.
