摘要: 随着城市化的发展，上海、北京等超大城市已经逐渐从土地增量扩展模式转变为存量发展模式，城市空间发展也更加关注集约高效、品质共享等需求。城市更新空间的识别和评估对土地资源利用、更新项目规划等具有重要作用。以上海市中心城为对象，从居住、工业和商业3方面运用因子分析、空间自相关、聚类分析等方法研究不同功能区的特征。研究发现，居住功能区中靠近外围地区的居住区更新需求更加显著；工业功能区中西北部靠近大场镇和南部靠近三林镇的区域急需更新；商业功能区中内环内人民广场、静安寺南京西路、陆家嘴等地区发展较好，周边地区急需更新。最后，结合聚类的方法识别出不同区域的更新重点导向，以期为城市更新项目的实施提供借鉴。
Abstract: With the development of urbanization, megacities such as Shanghai and Beijing have gradually changed from incremental land expansion mode to stock development mode, and urban space development also pays more attention to the demands of intensive efficiency and quality sharing. The identification and evaluation of urban renewal space play an important role in land resource utilization and renewal project planning. This paper takes the central city of Shanghai as the object. From residential, industrial and commercial aspects, the characteristics of different functional areas are studied by using factor analysis, hot spot analysis and cluster analysis. It is found that the residential renewal demand near the periphery area is more significant in the residential functional area. The industrial functional area near Dachang Town in the northwest and Sanlin Town in the south is in urgent need of renovation. The People's Square in the middle and inner ring, Nanjing West Road of Jing'an Temple, Lujiazui and other areas in the commercial function zone are developing well, but the surrounding areas are in urgent need of renovation. In addition, the clustering method is also used to identify the key orientation of renewal in different regions, providing references for the implementation of urban renewal projects.
