摘要: 社区生活圈逐步成为国土空间规划的核心概念。聚焦社区生活圈规划的前置性问题，提出理想社区生活圈与实际社区生活圈的概念体系与划分方法，并以北京市清河街道当代社区、怡美社区为例进行研究。基于地理空间数据的结晶生长模型，划分出理想社区生活圈范围；基于居民出行的GPS数据，划分出实际社区生活圈范围。城市社区生活圈的内部结构由“基本生活圈—弹性生活圈—共享生活圈”组成。理想社区生活圈呈现类似“摊大饼”式的扩张模式，而实际社区生活圈呈现出“点—轴”分布的结构，共享生活圈也呈现出相似特征。总体来说，本研究为深入理解社区生活圈的划分方法和居民日常活动及行为的关系提供了新的视角和思路。
Abstract: The concept of the Community Life Circle (CLC) is progressively emerging as a central element in territorial spatial planning.This study addresses the foundational issues pertinent to CLC planning, proposing a conceptual framework and delineation methodologies for Ideal Community Life Circles (ICLCs) and Actual Community Life Circles (ACLCs). Empirical research was conducted on two communities in Qinghe Street, Beijing: the Dangdai Community and the Yimei Community. Utilizing a crystal growth model based on geographic spatial data, we delineate the boundaries of ICLCs. In contrast, ACLCs are identified using GPS data reflecting residents' travel behaviors. The internal structure of urban community life circles is categorized into three hierarchical levels: Basic Life Circles, Elastic Life Circles, and Shared Life Circles. Our findings indicate that while ICLCs exhibit a "pancake-like" expansion pattern, ACLCs display a "point-axis" distribution structure, a characteristic also observed in Shared Life Circles. In conclusion, this research provides novel insights into the relationship between CLC delineation methods and residents' daily activities and behaviors, offering significant implications for future urban planning practices.
