为支撑并指导城市地上与地下公共空间的一体化、系统性规划建设，提出地下公共活动空间布局对城市公共中心体系协调作用的测度方法。基于兴趣点和人口活动强度数据分别识别城市公共中心体系和市民公共活动的空间格局，以计入、不计入地下公共空间兴趣点的城市公共中心体系格局和市民公共活动分布格局的相似度之差，度量地下公共活动空间的全局协调作用； 以城市公共中心相对于市民活动集聚中心点的偏移情况，度量局部协调作用； 最后，对上海市静安区进行实证研究。结果表明： 1）静安区地下公共活动空间布局主要在中微观尺度上发挥协调作用，作用强度随研究半径扩大而迅速减弱； 2）局部测度表明地下公共活动空间能对城市公共中心体系产生向心集聚和移心2类作用，前者提高发展滞后地区的公共空间供应效率，后者可将集聚效应转化为外溢效应； 3）静安区北部和苏河沿岸等区域存在移心作用失效的地下公共活动空间规划错位布局； 4）200、500 m研究尺度的全局测度和结合定性分析的局部测度能有效揭示地下公共活动空间的协调作用效果，适宜纳入城市公共中心体系建设情况的监测指标体系。

In this study, measurements of the coordinating effect of underground public spaces on the urban public center system are presented to support and guide the integrated and systematic planning of urban public spaces both aboveground and underground. The spatial patterns of urban public spaces and human public activities are identified based on points of interest and real-time population activity intensity data, respectively. The global coordinating effect of underground public spaces is measured by comparing the similarities between the patterns of urban public spaces (including and excluding underground public spaces) and human public activities. The local coordinating effect is measured by comparing the deviation of clustering centers of the three spatial distributions. The methodology is applied to an empirical study of the Jing′an district, Shanghai, China. Conclusions are drawn as follows: (1) The layout of underground public spaces in the Jing′an district primarily exerts a coordinating effect at the meso-and microscale, with the intensity of the effect decreasing rapidly with the expansion of the study radius. (2) The local measurements reveal and distinguish the centripetal and the centrifugal effects of underground public spaces: the former improves the efficiency of public space supply in lessdeveloped urban areas, whereas the latter transforms an agglomeration effect into a spillover effect. (3) There is a staggered layout of underground public spaces in the northern part of the Jing′an district and along the Suhe creek, where the centrifugal effect exists. (4) Global measurements with 200 m and 500 m radii, combined with local measurements and qualitative analysis, can effectively reveal the coordinating effect of underground public spaces and are suitable for inclusion in the monitoring index system for the construction of urban public center systems.
