基于低碳出行方式的南京市本地居民景点可达性研究

以南京市为研究区，选取22个3A级及以上旅游景点，基于ArcGIS平台可达性计算的网络分析与栅格分析方法，分析了在步行+共享单车+地铁新型低碳出行方式之下，现阶段和地铁第二期建设完成阶段居民到达旅游景点的最短时间与平均时间以及变化情况，发现二期地铁的建设使旅游景点的平均时间可达性减少了3.96 min；现状地铁下有8个旅游景点可达性较好，14个一般，二期地铁建设完成后，将有16个景点可达性较好，6个一般；老城区内居民前往景区的平均时间可达性内部差异小，栖霞区、江宁区、雨花台区、浦口区内部差异大；有62.87%的区域在二期地铁的建设下可达性变化在5 min之内，可达性变化大的区域基本与二期新增地铁线路经过的区域一致。

Attractions’ Accessibility of Local Residents in Nanjing: Based on A Low-carbon Trip Mode

Taking Nanjing as research area, based on the new type of low-carbon travel mode, walking and bicycle sharing and subway, combines the network analysis with the grid analysis method of accessibility calculation by ArcGIS, and chooses 22 tourist attractions of 3A level or above, it analyzed the average time, the shortest time and the change time of residents reached to scenic spots, based on the current and future construction of Nanjing subway. The paper found that the second construction of subway reduced the average time accessibility of tourist attractions by 3.96 minutes; Based on the current subway, 8 tourist attractions’ accessibility is good, 14 tourist attractions’ accessibility is common, after the second construction is completed, 16 attractions’ accessibility is good, only 6 is common; The old city has a small difference on the average time, which residents reached to the scenic spots, while Qixia district, Jiangning district, Pukou district and Yuhuatai district have big differences; In the second phase of the subway construction, 62.87% of the area changes the accessibility within 5 minutes and the area with large changes in accessibility basically coincide with the areas that the newly added subway lines of the second phase pass through.
