基于手机信令数据的上海城市公园供需服务分析

摘要:
利用手机信令大数据,通过对在户外游憩活跃期到访过上海大型城市公园的游客进行空间位置的追踪,尝试寻找游客来源地,直观描述公园的空间服务范围,即“实达性”。将32个大型城市公园“实达性”范围内的游客样本数据与上海街道空间单元进行连接,结合相应单元中可识别出的信令数据样本,计算各街道的公园出游率,比对街道单元中居民的公园使用需求。结合公园空间位置,将上海被大型城市公园服务的区域分为高需低供、高需高供、低需高供、低需低供4类,对每类区域的公园服务特征进行了评价;根据不同类型区域中区级与社区级公园的供给情况,结合《上海市城市总体规划(2016-2040)》中的区域公园布局,对新建大型公园的选址与建设优先次序提出了建议。

Abstract:
The research uses the big data of mobile phone signaling to locate the visitors of large city park in Shanghai during the active outdoor recreation period. The locations of park visitors' homes have been found. And it is able to describe park's "real" service area. The visitors sample data in the "real" service areas of the 32 large urban parks are connected with the Shanghai street space unit, and the park emissiveness of the units are calculated according to the numbers of park visitors whose home location is in the unit and the population in the corresponding unit. With the recreation demand expressed by emissiveness combined with the park supply expressed by park location, Shanghai can be divided into four types of areas which are high demand for low supply, high demand for high supply, low demand for high supply, low demand for low supply. Each type of park service characteristics have been described. According to the supplies of large and community parks in different areas, this paper puts forward some suggestions on the location and construction priorities of the new large parks. And the order of construction priority of regional park layout in "Shanghai Master Plan 2016-2040" is also suggested.
Key words:  urban park  supply-demand balance  mobile phone signaling data  space distribution  Shanghai
