Research On Defense Safety Design For The External Environment Of Changchun Residential Block

With the rapid development of Chinese social and economic development, people’s living standards improve, but the crime rate in urban residential areas, but straight up, so the living environment of security issues become the focus of attention.External environment through the design of the building, residents can create a safe living environment, reduce the incidence of crime, to some extent, however, as Chinese residential block appeared earlier collection of residential portfolio model, initial design did not adequately consider the safety factor, defects outside the building environment, so outside the building blocks of residential security issues environmental Defense study has important significance.Firstly, through the selected research background begin to understand the importance of research, through the study of relevant data at home and abroad, to " Crime Prevention Through Environmental Design "(CPTED) theory and "the Urban Physical Environment Vulnerable to Crime "theory writing basis.After determining the paper frame, the use of data analysis, the actual investigation, comparative analysis and questionnaire on the status of Changchun City block of residence to investigate and analyze the material factors that affect the living environment of defense blocks away safe and non-material factors which form the building material factors including the layout of the space, the road system, landscape layout light environment and residential block, non-material factors mainly refers to residential block management. By summing up the results of the residential block factors outside the building environmental problems:(1) building space feel there is obviously insufficient;(2) road system is not standardized;(3) landscape layout very lacking;(4) equipped with lighting facilities not complete;(5) living neighborhood management model is unreasonable.Outside the building blocks of living environment is a necessary existence is inseparable from people’s daily life places, the author proposed for the problem, combined with defensive security-related knowledge, presented with a targeted approach in the final of the feasibility and opinion.At present, Chinese security for defense research has just started, is available for reference and inspection of materials not many, so I hope that by studying the results of this paper, in order to provide reference materials related fields.
