Study On Comprehensive Park Of Nanchang From The Perspective Of Security

The comprehensive park is part and parcel of the urban green space system.It is a place to meet the leisure needs of urban residents,provide rest,excursions,exercise,exchanges,and organize various collective cultural activities.Therefore,people's needs are the core of park construction.In the level of human needs,second only to the physiological needs is the security needs.The sense of security is the most fundamental feeling of people,which will directly affect other feelings and behaviors.Previous studies have paid more attention to the satisfaction of tourists and the law of landscape preference.This dissertation takes the safety of tourists in the park environment as the research direction,do the conducts field research and questionnaire survey on three large comprehensive parks in Nanchang.Exploring the influence of various landscape elements of the comprehensive park on the safety of tourists,the weight coefficient of each landscape element and the similarities and differences of the security feelings of different characteristic groups in the park environment.By using the analytic hierarchy process,principal component analysis method,Delphi method and other methods to construct the comprehensive park landscape security evaluation system,including six first-level indicators including water body,topography and geology,road and square,plant community,facilities and skits,overall environment,and 26 second-level indicators including water depth,water bank protection,water quality and hydrophilic experience activities,and the weight coefficient of each indicator was calculated through the survey data.A landscape security evaluation survey was conducted on the three comprehensive parks of Bayi park,people's park and Ganjiang citizen park in Nanchang city,and it was concluded that the security score was 3.25 for Ganjiang citizen park,2.98 for people's park,and 2.95 for Bayi park.According to the classification of landscape elements,the scores from low to high are 2.86 for road square and 2.99 for facility sketch,3.03 for water body,3.06 for overall environment,3.19 for topography and geology,and 3.27 for plant community.Research on the similarities and differences of the sense of security of different characteristics of people in the park environment,which shows women have a lower sense of security than the male group.In the five variables of park water depth,high platform protection plant canopy closure,night lighting facilities,and paving slip resistance,women's safety assessment was significantly lower than that of men;children's fear of park water depth was significantly higher than other groups;In the nine variables,such as the slope of the park site,the protection of the platform,and the flatness of the pavement,the safety assessment was significantly lower than that of the younger group;People who had been exposed to danger or accidental injury in a park or other outdoor green space rated their sense of safety significantly lower than those who had no such experience;the difference of education degree and frequency has no significant influence on the safety evaluation of the park.Combining the existing problems in the construction of comprehensive parksecurity and the evaluation system of comprehensive park landscape security,this dissertation proposes security improvement strategies and design suggestions from the perspectives of park landscape elements and crowd characteristics security differences.It is expected to reasonably create the park landscape environment,improve the visitor experience security,and provide reference for the construction of comprehensive park safety and relevant practitioners.
