摘要/Abstract

推动新城空间的成熟化、品质化转型已成为当前城市建设的趋势,但目前尚缺乏可以精准、定量开展新城空间形态成熟度评价的方法。研究立足量化城市形态学,在经典城市形态分析方法的基础上加入街景大数据和新分析技术,同时结合中国建成环境特征开展在地化指标调整,尝试构建适宜本土的城市形态成熟度的定量评价体系。以上海五大新城为例和一个历史片区,对城市形态成熟度开展测度分析;并统计专家共识与分析结果相校核,证明了该方法的有效性;进而提出针对性的设计导则,为城市更新提供精准支持。此外,由于该方法主要基于开放易得的多源数据开展分析,后续可进一步支持更大范围的城市空间评估,为新城空间形态品质提升提供兼具全局视野和细节图景的研判支持 

In China, in recent years it has become a prevailing trend to promote the spatial maturity and high-quality transformation of new towns, yet there are few quantitative methods to evaluate their urban morphological maturity. From the perspective of quantitative urban morphology, this paper integrates street view data and cutting-edge analytical techniques into classic urban morphological study and develops a quantitative index for evaluating urban morphological maturity that fits Chinese cities by adjusting the indicators in line with the unique characteristics of the built environment of Chinese cities. Focusing on five new towns, as well as a historic area, of Shanghai, the paper evaluates their urban morphological maturity with this quantitative index and verifies its validity by comparing the evaluation result with that of expert consensus. It then proposes some design guidelines that may provide robust support for the regeneration of these new towns. Given its reliance on the multi-source data of open access and ready availability, this index holds promise for evaluating the urban morphological maturity of other new towns, to provide support for urban form improvement from both holistic and detailed perspectives.
