在以机动车交通为主导的当代城市中，如何改善步行环境是一项严峻的挑战。本研究提出一种将若干个街区作为一个集合，并在其区域内实行步行优先的城市大街区步行模式，以创建城市步行化单元。同时基于自组织理论，将区域内与步行系统相关的资源配置与空间组织结构的拓扑关系量化建模，以实测、仿真、问卷等方式提取优秀样本案例相关数据，进行空间结构的拓扑学分析，揭示城市空间结构自组织演化规律，并结合空间句法对城市空间形态自组织演化规律进行探索；以GIS结构方程等科学方法对区域交通组织、交通方式、碳排放等进行量化计算；同时结合空间句法和GIS等软件分析步行者需求、空间感知和行为特点，以路径、节点、空间形态及功能支持等多层面关联因素的评估和优化为目标，建立区域内步行系统空间体系的拓扑模型，实现区域步行化，有效利用机动交通便利性，鼓励低碳出行，强化城市安全，同时为机动化时代的城市发展提供一种具有步行适应性的规划模式。

In contemporary cities which dominated by motor vehicle traffic, it’s a very urgent challenge how to improve the pedestrian environment. This study proposes a pattern which multiple blocks as a unit to implement pedestrian priority area in the city. Based on the city self-organization theory, the study quantificationally modeling the topological relationship between the spatial structure and resource configuration related with the pedestrian system. The study extract the key database through empirical measurement, simulation, questionnaires, etc. from sample cases, and analyzing the topological space structure to reveal the evolution of urban spatial self-organization. Meanwhile the study also explores the morphological evolution of space self-organization by the tool of space syntax. And the study calculates the traffic organizing, transportation means and carbon emission etc. by the scientific method, such as GIS structural equation. It analysis the pedestrian user needs, spatial perception and pedestrian behavior characteristics etc. by program like space syntax and GIS and so on. It creates the spatial topological model to optimize the multiple relevant factors like pedestrian path, nod, place, and spatial form etc. The topological model will propose the methodology and analyzing means to urban regional pedestrianizing, motor traffic efficiency, low carbon community creation, and urban security enhancement. Thus provide a new pedestrian adapting urban planning pattern for the urban development and new urban area construction in the motor vehicle era.
