摘　　要：随着健康生活的理念深入人心,人们对公园绿地的数量及品质提出了更高的要求,而可达性可以有效评价公园绿地设施布局是否合理。本研究以成都市青羊区为例,利用两步移动搜索法对青羊区公园绿地可达性进行分析,并结合可达性冷热点分析进一步探究了青羊区公园绿地分布的合理性。结果显示:青羊区大部分区域可达性较低,空间差异化较大,整体呈现可达性水平由南部草堂街道向两边逐渐降低的格局,造成可达性不均衡的主要原因是人口需求与绿地供给水平的不匹配。文章希望通过开展此项研究,从而为公园城市建设提供参考。With the concept of healthy life deeply rooted in people’s hearts,people have put forward higher requirements on the quantity and quality of park green space,and the accessibility can effectively evaluate whether the layout of park green space facilities is reasonable or not.In this study,the accessibility of parks and green spaces in Qingyang District,Chengdu,was analyzed with the two-step moving search method,and the reasonableness of the distribution of parks and green spaces in Qingyang District was further explored by combining with the analysis of accessibility cold hotspots.The results indicated that the accessibility of most areas in Qingyang District is low,with large spatial differentiation,and the overall accessibility level gradually decreased from Cao Tang Street in the south to the two sides,and the main reason for the imbalance of the accessibility was the mismatch between the population demand and the supply level of green space.This paper aims to provide a reference for the construction of park city.
