摘要
公园绿地的可达性对于提升民生福祉、环境公平及城市高质量发展具有深远意义。综合考虑公园绿地的主观和客观供给能力,基于公园绿地规模、网络好评度、高德地图API路径规划等数据,运用高斯两步移动搜索法测度了居民单一出行及多交通出行模式下福州市公园绿地的客观和主观可达性,得出以下结论:(1)同一出行模式下公园绿地的主客观可达性差异大,客观可达性的高值区主要分布在非中心城区,而主观可达性的高值区大多分布在中心城区;(2)不同交通出行模式下主观和客观可达性也存在差异,步行出行模式下的公园绿地可达性低于驾车和公共交通出行模式的可达性,综合出行模式的可达性分布与驾车可达性分布相似,尚未形成公共交通主导的公园绿地发展模式;(3)公园绿地主客观供需平衡的县域少,供需不平衡的县域多,高人口密度县域存在公园绿地供给小于需求问题,非中心城区县域公园绿地主客观供需比普遍较低;(4)步行、驾车、公共交通出行模式下的高客观供需比-高主观供需比的公园绿地仅三坊七巷和福州市贵安新天地休闲旅游度假区,超过70%的公园绿地属低客观供需比-低主观供需比类型。本研究不仅关注公园绿地的空间可达性,也基于人的感受对公园绿地的主观可达性加以测度,为可达性评价提供新的研究思路,同时也为福州市公园绿地资源配置和存量绿地的质量提升提供建议。
The accessibility of green parks is of significance to the promotion of people′s livelihood and well-being,the environmental equity and high-quality urban development.In this paper,based on the green park scale,network evaluation,Amap API path planning and other data,the Gaussian two-step floating catchment area method is used to measure the objective and subjective accessibility of green parks in Fuzhou City under single travel mode and multi-traffic travel mode.The results show that:(1)There are great differences in subjective and objective accessibility of green parks.The high-value areas of objective accessibility are mainly distributed in non-central urban areas,while the high-value areas of subjective accessibility are mostly distributed in the central urban areas.(2)There are also differences between subjective and objective accessibility under different travel modes.The accessibility of green parks under walking travel mode is lower than that of driving and public transport travel mode.The accessibility distribution of comprehensive travel mode is similar to that of driving accessibility,and the green space development model dominated by public transport has not yet been formed.(3)There are fewer counties with the balanced supply and demand,and there are more counties with imbalance between supply and demand.In the counties with high population density,the demand exceeds the supply of green parks.The ratio of objective and subjective supply and demand of green parks in non-central urban areas is generally low.(4)The green parks with high objective accessibility-high subjective accessibility under the mode of walking,driving and public transport are the Three Lanes and Seven Lanes and Guian Xintiandi Leisure and Tourism Resort in Fuzhou City,and more than 70%of the green space belongs to the type of low objective accessibility-low subjective accessibility.The study not only pays attention to the spatial accessibility of green space,but also measures the accessibility of green space from human feelings,so as to provide new research ideas for accessibility evaluation.At the same time,it also provides suggestions for the allocation of green space resources and the improvement of green space quality in Fuzhou City.
