Research on the Defense Safety Design of Building’s Outer Environment Based on Weaken the Spatial Blind Area—— Take Gated Residential Communities in Changchun as an Example

Abstract

Rapid urbanization and planning idea of huge block lead to the special urban space structure in most China city. Combined with the construction of urban connotation lags behind, serious results in the highlight problem of pathological environmental issues that predispose crime, such as the spatial blind area. Buildings’ outer environment is significant for some kinds of crime. Spatial blind areas are adverse to crime prevention and control which is a key issue of the defense safety design. A favorable buildings’ outer environment(abbr: BOE) provides an entertainment and communication place for residents. However, the unfavorable BOE might bring about spatial blind areas. The author puts forward three kinds of spatial blind areas, which are the position-based spatial blind area, the morphology-based spatial blind area and the atmosphere-based spatial blind area. Taking Changchun gated residential communities as an example, the author analyzes the components of residential BOE, such as building element, landscape element and the path elements. Ultimately, the author proposes the strategies of defense safety about how to reduce spatial blind area.
