摘要
文章以湖南省森林植物园为研究对象,利用问卷调查获取游客样本数据,通过RiverMap获取影像和路网数据,并基于ArcGIS平台分析服务半径的辐射特点和现有路网可达性,结果表明:1)湖南省森林植物园游客随1 km,4 km,7 km不同服务半径范围向外辐射分层分布,且在北—西方向上辐射距离更远;2)老年群体表现出更强的1 km服务范围的分布倾向,中青年愿意支付更多的距离成本,从不同服务半径范围获取公园服务;3)湖南省森林植物园15 min步行、非机动车、机动车出行范围的实际服务覆盖面积比例仅分别达到24.61%,38.04%,50.40%,整体可达性相对较差。基于辐射特点及其年龄特征,提出包括丰富现有路网出行方式、增加出入口、提供更多(非)机动车使用机会等可达性提升对策,以进一步提升城市生态空间服务能力。
This research uses questionnaires in the Hunan Forest Botanical Garden to obtain tourist sample data,and also obtains images and road network data through RiverMap.Based on the data,the paper analyzes the radiation characteristics of the service radius and the accessibility of the existing road network using the ArcGIS platform.The results show that:1)The visitors in the Hunan Forest Botanical Garden are distributed in layers with different service radius of 1 km,4 km and 7 km,and they radiate farther in the direction from the north to the west;2)The elderly people tend to be more distributed in the service range of 1 km,while the middle-aged and young people are willing to pay more distance costs to obtain park services from different service radius areas;3)The actual service coverage ratios of 15-minute walk,non-motorized travel and motorized travel in the Hunan Forest Botanical Garden are only 24.61%,38.04%,and 50.40%,respectively,and the overall accessibility is relatively poor.Finally,based on the radiation characteristics and age characteristics,some countermeasures are put forward for accessibility improvement,including providing more road network travel modes,increasing entrances and exits,and making the non-motorized travel more in use,so as to improve the urban capacity in ecological space services.
