| The design of defense safety refers to the improvement of people’s living material environment,which makes the external space have the function of increasing the difficulty of crime and preventing crime.The text selection point is the Shengtai square area of Changchun City,which is the new urban area of Changchun City.With the acceleration of economic construction and urbanization,a lot of pathological space caused by improper environmental design has been formed.As a result,people work here and life safety feelings have been reduced.Therefore,through the collation and analysis of the existing literature,the building elements,traffic elements and service facilities elements in this area are selected,and the problems existing in the design of the external environment of the building are analyzed based on the theory of daily behavior,and the design suggestions and improvement suggestions are put forward.Routine Activity Theory is a branch of the theory of "CPTED(crime prevention through environmental design)".the use of "Routine Activity Theory " to explain criminal behavior is based on the three main components of the theory: motivated offenders,suitable targets,and lack of effective surveillance.The outside environment is the carrier of crime,and its design will affect the behavior of daily environmental participants.People’s daily behavior can be mainly summed up as necessary activity,spontaneous activity,social activity.This paper combines Routine Activity Theory with three main daily behaviors.Based on this theory,this paper discusses how the design of external environment affects the occurrence of criminal behavior.By means of questionnaire and interview,the results of the questionnaire are analyzed by spss analysis software,which includes reliability analysis,factor analysis,multiple linear regression analysis,and then draw a conclusion.The previous research on defense security design based on Routine Activity Theory at home and abroad mainly focuses on the behavior of offenders,but the study of daily ordinary environmental participants is rarely involved.Therefore,this paper analyzes the feelings of the actors in this area from different angles,and then reveals the defects of the built environment and attracts public attention.Based on the Routine Activity Theory,the design strategy of defense safety is put forward,and the final purpose of this paper is to establish the defensive space in the ecological square area. |
