Research On Defense Safety Design Of Building's Outside Environment In Urban Rural Fringe Areas Of Changchun City

Urban-rural fringe areas refer to the combination areas of urban and rural areas,it is a special area where the city expands to the countryside,the countryside integrated into the urban areas,with the role of link between the city and the village.However,due to its own ambiguous,dynamic,complex and complex characteristics,so that there are more safety risks in the outer environment of buildings,easily leading to crime.Therefore,it is of great significance to study the defense safety of outer environment of buildings in the urban-rural fringe areas.At present,China's research on the defense safety of outer environment of buildings is still in its infancy,and the research on the of urban-rural fringe areas is very few.The paper studies defense safety of outer environment of buildings in the urban-rural fringe areas of Changchun City,Based on the characteristics of defense safety,the urban-rural fringe areas of Changchun City are divided into three different types,namely,the urban-rural fringe areas of industrial landdominated,the urban-rural fringe areas of residential-dominated,and the urbanrural fringe areas of agricultural land-dominated.And it analyzes and summarizes the four key locations of defense safety of outer environment of buildings,namely spatial node,linear road,transition boundary and spatial area.Through the investigation of three different types of the urban-rural fringe areas in Changchun City,this paper analyzes the defense safety problems in four different locations by combining the crime pattern theory in the field of criminology.Finally,the author puts forward the feasible strategy of defense safety design for the specific situation of the urban-rural fringe areas in Changchun City by using the crime pattern theory.The purpose of this study is to expand the scope of defense safety research,so that it is not limited to residential areas,urban public space and other fields,but the special area of the urban-rural fringe areas that aren't not involved in,through the feasibility of the design strategy to prevent crime,in order to improve the quality of life of residents in urban-rural fringe areas and to protect the personal and property safety of residents,and to provide theoretical basis and design basis for the defense safety design of outer environment of buildings in the urban-rural fringe areas in the future.
