| In the early days,most of Chinese urban parks adopted enclosed design and closed-end management,which made the parks isolated from the outside cities.Under the condition of limited resources,the way was conducive to the safety of the park,but constrained the use efficiency of the park to a certain extent.With the rapid development of Chinese social economy,the city park as the scarce resources,quality and public welfare widely attention,the city park quality has become one of the important indicators to reflect the quality of the city life,therefore improving the public of the park has become a hot topic of many cities.The construction practice of "park City" in Chengdu,the construction goal of "Forest City" in Shenzhen,and the "Cloud Road","Green road" and "open and accessible park" in Guangzhou share the common characteristics of promoting the opening and accessibility of parks and realizing multiple effects such as landscape,activities and social and economic benefits.The change of the urban park boundary from closed to open greatly improves the accessibility of the park,but also brings challenges to the safety of the park.In this process,the cost of park management is greatly increased,and the demand for people and technology is constantly increasing."What changes have happened to visitors’ perception of safety?" "How does park security respond from space environment design to safety management?" Have become the difficulty to be solved urgently.Overseas for safety perception of theory and practice research have certain forwardlooking,such as maslow’s hierarchy of needs from the demand side of the person to show us the importance of security,can defend a space theory,the environmental design theory of crime prevention,situational crime prevention theory and the broken window theory to us this paper expounds the influences of the safety awareness of different levels of the element.In this context,through the analysis and comparison of relevant theories abroad,the guiding role of the theory of Crime Prevention by Environmental Design(CPTED)as the theoretical basis is determined.Based on this theory,taking Guangzhou urban Comprehensive Park as the research object,the surrounding environment,boundary space environment design and boundary space control form were investigated on site,the environmental characteristics of open boundary space of urban park were analyzed,and the safety perception evaluation system was constructed with the help of analytic hierarchy process.Then,through the questionnaire survey method,respectively to the Liwan Lake Park,Tianhe Park and Huangpu Park issue based on the evaluation system of questionnaire investigation,the evaluation results proved the feasibility of the evaluation system,and reflects the space present situation of guangzhou city park open boundary field weakening,monitoring using the deficiencies and the phenomenon such as channel control is weak.Finally,according to the evaluation results,the improvement strategies of material space,safety technology and later management are proposed.It is hoped that while attracting the attention of all parties on how to open the urban park,we should also pay attention to the safety problem after the opening,so as to reduce the park management cost,improve the management eff iciency,make visitors feel at ease in the open urban park,and make a contribution to promote the opening of Guangzhou urban park boundary. |
