可防卫空间理论与犯罪防预性环境设计

20世纪70年代初，纽曼的《可防卫空间》系统地探讨了社区环境设计与犯罪预防，标志着一个新研究方向的兴起．虽然对可防卫空间理论的评价褒贬不一。但它成功地诱发新一轮的针对城市环境与城市犯罪关联的探索，其中影响较大的要属CPTED(Crime Prevention Through Environmental Design)。即犯罪防预性环境设计．因此。详细地介绍可防卫空间理论与CPTED的基本内容及相关联系，吸取国外经验，对我国城市和社区的发展有重要的指导和借鉴意义．

Defensible Space Theory and Crime Prevention Through Environmental Design

At the beginning of the seventies of 20 century, Newman's Defensible Space Theory systematically discussed the possibility of making crime reduction through community design, which indicates the rise of a new research direction. It has been bringing out a new round of investigation into the relationship between city environment and city crime. Now the CPTED among those research is gaining much momentum and attention. The two theories and their relationship are expounded. It is beneficial to take in foreign experiences and apply them to the urban and community development in China. But the CPTED is limited to some extent and it is part of a comprehensive crime prevention program. There must be a difference between reducing the motive for crime by social prevention and reducing the opportunity for crime by physical prevention. Motive reduction and opportunity reduction should come into combination.
