以济南市主城区为研究区域,以边长300 m的六边形聚合居住区为研究单元,采用多级半径的高斯两步移动搜索法,分析2010年和2021年不同级别公园绿地步行可达性和综合可达性的时空特征,并利用地理探测器探寻公园绿地可达性空间分异的影响因素.结果表明:(1)2010-2021年济南市主城区三个等级公园绿地的可达性均值都得到了提升,且可达性均值和提升幅度Ⅰ级＞Ⅱ级＞Ⅲ级,Ⅰ级公园绿地可达性空间格局在原来"核心—组团"的基础上增加了"带状"布局,Ⅱ级和Ⅲ级公园绿地可达性分别表现为"组团状"和"散点状"布局;(2)济南市主城区公园绿地综合可达性平均值提高,济南市主城区步行15 min以内能到达公园绿地的居民比重由2010年的42.94％提高到了59.53％,综合可达性空间格局及其演变呈现出与Ⅰ级公园绿地相似的特征,并在主城区东部出现与城市建设方向相一致的"组团扩散"现象;(3)公园绿地可达性的空间格局受"供给—连接—需求—社会经济"4个因素的综合影响,不同等级公园绿地可达性的影响因素趋同,但各因素的影响强度存在明显分异,影响强度的差异随着公园绿地等级的下降而增大.
Analysis of Spatiotemporal Evolution and Influencing Factors of Accessibility of Multi-level Park Green Spaces in the Main Urban Area of Jinan City at the Cellular Scale
The main urban area of Jinan is taken as the research area,and the hexagon converged residential area of 300 m side length is taken as the research unit.Using the multistage radius Gaussian two-step mobile search method,the paper analyzes the tempo-ral and spatial characteristics of the walking accessibility of different levels of park green space and the comprehensive accessi-bility of park green space in 2010 and 2021.The factors influencing the spatial differentiation of the accessibility of green space in parks are explored by means of geographic detectors.The results show that:(1)From 2010 to 2021,the average accessibility of green space in three levels of parks in the main urban area of Jinan has increased,and the average accessibility of Grade Ⅰpark green spaces is the highest and the improvement is the greatest.The spatial pattern of accessibility of green space in GradeⅠ parks has increased by"ribbon"layout on the basis of the original"core-cluster".The accessibility of green space in Grade Ⅱand Grade Ⅲ parks is"cluster-like"and"scattered",respectively.(2)The average comprehensive accessibility of park green space in the main urban area of Jinan increased from 42.94％in 2010 to 59.53％in 2021,and the spatial pattern and evolution of comprehensive accessibility showed similar characteristics to Grade Ⅰ park green space,and the phenomenon of"cluster diffusion"in the eastern part of the main urban area was consistent with the direction of urban construction.(3)The spatial pattern of the accessibility of park green space is comprehensively affected by four aspects of"supply-connection-demand-social economy".The influencing factors of the accessibility of different levels of park green space are similar,but the influence intensity of each factor is significantly different.Besides,the difference of influence intensity increases with the decline of park green space grade.
