摘　　要：城市公园绿地是城市生态系统的重要组成部分,是展示城市整体环境水平和居民生活质量的重要指标。以开封市鼓楼区城市公园绿地为研究对象,结合道路网结构,运用网络分析方法,以步行、骑行两种低碳出行方式,计算了公园绿地在不同出行时间下的可达性范围。结果表明:步行方式下15 min内仅能覆盖研究区29.9%的城市公园绿地,骑行方式下15 min内可以覆盖研究区89.6%的城市公园绿地,均无法充分满足居民对绿地的使用需求;研究区内公园绿地存在分布集中,各街道分布不均衡等问题。研究结果可以为研究区内的城市公园绿地优化配置给出一定的科学指引。Urban park green space is an important part of the urban ecosystem and an important indicator to demonstrate the overall environmental level of the city and the quality of the residents’ life. This paper takes urban park green areas in Gulou District of Kaifeng City as the research object, combines the road network structures and uses the network analysis method to calculate the accessibility range of park green areas under different travel time by using two low-carbon travel modes, walking and cycling. The results show that the walking mode can only cover 29.9% of the urban park green space in the study area within 15 minutes, while the cycling mode can cover 89.6% of the urban park green space in the study area within 15 minutes, which cannot fully meet the residents’ needs for the use of green space. There is a concentration of parkland in the study area, with an uneven distribution across streets. The results of the study can provide some scientific guidelines for the optimal allocation of urban parkland in the study area.
