| 摘 要： | 随着环境变化加剧、技术进步扩散、城市化生活转向等因素的交织叠加,日常活动空间的供需过程需要并可以更具韧性,但既有研究鲜有涉及。因而,聚焦中国社会经济发展主要矛盾,挖掘面向城市居民日常活动与环境供需矛盾的城市韧性内涵,建构有机整合的理论框架和评估指标体系,并以南京市中心城区为例,依托地理大数据支撑,进行日常活动-环境系统的韧性评估及空间特征研究。主要结论：① 韧性要素在活动与环境间以及数量与质量之间的供需结构失调,且供需不均衡和不充足的问题同时存在并相互制约。② 活动韧性、环境韧性各自的空间分异显著且供需水平及相互匹配程度较低,导致系统韧性呈现低水平蔓延的空间形态。③ 活动韧性、环境韧性及系统韧性之间的空间支撑或匹配作用没有充分发挥,导致日常活动空间的供需关系分异较大且缺少连续良性的空间互动。基于此,应根据韧性演进阶段,促进日常活动空间供需网络的整体动态协同优化。

| Abstract: | With the interaction of environmental changes, technological progress, and urbanized life, the supply-demand process of daily activity space needs and can be more resilient, but the existing study is rarely involved. Therefore, this study focuses on the main contradiction of China's social and economic development, excavates the connotation of urban resilience under the scenario of supply-demand contradictions between daily activities and the environment, and then constructs an organically integrated theoretical framework and evaluation index system of urban resilience. Finally, taking the central urban area of Nanjing as an example, and relying on the support of geographical big data, the comprehensive evaluation on spatial characteristics of daily activity-environment system resilience is carried out. The main conclusions are as follows: (1) The structure of supply and demand of resilience factors between activities and environment as well as between quantity and quality is out of balance, and the imbalance and insufficiency of supply and demand exist simultaneously and restrict each other. (2) The spatial distribution of activity resilience and environmental resilience is significantly different, and the level of their supply and demand is low, as well as the degree of their mutual matching, which resulted in a spatial pattern of low-level spread of daily activity-environment system resilience. (3) The spatial support or matching role among activity resilience, environmental resilience, and system resilience has not been fully exerted, leading to serious differentiation of supply and demand of daily activity space, and lack of continuous benign interaction in spatial distribution. Therefore, the overall dynamic synergistic optimization of the supply and demand network of daily activity space should be promoted according to the evolution stage of resilience. In short, for urban resilience research, this paper has some reference value for the expansion of cross-fields, the integration of theoretical frameworks, the optimization of evaluation methods, and the implementation of governance concepts. |
