广州市海珠区绿道分布与可达性研究

Study on the Distribution and Accessibility of Greenways in Haizhu District,Guangzhou City

在高质量发展和提升民生福祉背景下,对广州市海珠区绿道可达性进行研究可促进游人便捷地享有绿道服务,为进一步提升海珠区绿道服务。本研究基于ArcGIS空间分析技术和网络分析法,对海珠区现状绿道在不同的出行方式下进行可达性研究。研究结果表明:①海珠区绿道整体连接通畅度欠佳,空间分布呈“西疏东密”,数量长度呈现“西少东多”的不协调布局。②0~15 min的绿道可达性服务范围内,步行、骑行、机动车可达服务区累计占比分别为53.10%、90.60%、92.96%。③综合三种出行方式,海珠区整体绿道可达性情况良好。

In the context of high-quality development and the improvement of public welfare,this paper aimed to facilitate convenient access to greenway services by the visitors in Haizhu District,Guangzhou,thereby offering insights for enhancing the service of greenways in the region.Utilizing spatial analysis techniques and network analysis methods in ArcGIS,the paper studied the accessibility of the existing greenways in Haizhu District under various modes of transportation.The results show that:①the overall connectivity of the greenways in Haizhu District was not good enough,with a spatial distribution characterized by“sparse in the west,dense in the east”,and an imbalanced layout in terms of quantity and length showing“less in the west,more in the east”.②The service area accessible within 0~15 minutes via greenways,by walking,cycling,and motorized transport,was 53.10%,90.60%,and 92.96%respectively.③Integrating all three modes of travel,the overall accessibility of greenways in Haizhu District was good.
