结合空间组构与环境犯罪学,初步建构基于空间句法的犯罪分布环境阐释理论。以武汉市中心城区为案例区域,以立案判决的2013年盗窃罪、抢劫罪和抢夺罪案件分布地点为数据源,以典型犯罪空间为实证研究对象,解读城市"两抢一盗"犯罪现象的分布环境。宏观尺度下,空间组构自发涌现的城市节点容易成为犯罪吸引场,与犯罪热点区分布形成密切关系;节点可达性衔接宏微观空间,影响犯罪人到达、逃逸犯罪地点成本的大小以及犯罪失败风险的高低;微观尺度上,局部空间与整体空间割裂形成的"空间缝隙"为犯罪人的空间探索创造了可能,空间的高集成度与空间使用者的单一化强化了犯罪集聚;空间拓扑深度则通过塑造社区人流的社会结构与领域感影响犯罪的空间防卫。空间句法为分析犯罪人的滋生环境、犯罪动机的刺激环境、犯罪人"到达"、"实施"、"逃逸"的活动环境以及防卫犯罪活动的约束环境提供了有力支撑。
By integrating spatial configuration and environmental criminology theory, this study tentatively constructed a theoretical framework for elucidating crime distribution environment based on space syntax. Address- level crime data from law court was used to interpret the distribution environment of robbery, snatch and theft crime. The central area of Wuhan was taken as a case study area, and several typical crime spaces were analyzed for further empirical studies. This research showed the following four results:(1) Under the macroscopic space, crime hot spots are closely associated with crime attractors, which are the spontaneous emerging urban nodes in spatial configuration.(2) The accessibility of urban nodes that link the macroscopic spaces with the microcosmic ones, has an impact on the cost of arriving at and escaping from crime locations and the risks of failure.(3) Under the microcosmic space, the "spatial gap" generated by the separation of global and local space,creates potentials for criminals' spatial exploration. Meanwhile, homogeneous use of space intensify crime concentration with high integration.(4) By forming the social structure and territoriality of a community, the topological depth of space influences the defense space. In conclusion, the proposed space syntax method provides a theoretical and technical support for systematically elucidating the breeding environment of criminals, the stimulation environment of criminal motive, the criminal activation environment and the constrained environment for preventing criminal activities.
