Evaluation On The Suitability Of Shock Absorbers And Disaster Mitigation In Nanning City Park

With the frequent earthquakes in recent years,the park's function of shock absorber and disaster reduction has been paid more and more attention.The suitability of shock absorbers and disaster mitigation in urban parks can reflect the strength of emergency shock absorbers and disaster mitigation function in urban parks and reflect the construction level of urban parks in terms of shock absorbers and disaster mitigation.This study through literature reading,field investigation and expert consultation methods such as affecting the urban park suitability index to select suspension and mitigation,and furthermore through questionnaire investigation and expert consultation method of relevant indicators are compared,and the weight at the same time with the help of AHP analytic hierarchy process(AHP),the analysis model is established based on the survey data of city park,with safety,accessibility,efficiency and service four aspects and 14 indexes of nanning city center within the existing 14 city park suitability for suspension and mitigation,and the results are as follows:(1)AHP was applied to consult relevant experts to obtain the order of importance of factors on suitability:in the criterion layer,security>accessibility>effectiveness>service;In the factor layer,the topography has the greatest influence on the intensity,and the garden road network density has the least influence.(2)Based on the investigation and analysis of urban park,after the results of model calculation,after an earthquake disaster reduction get city park suitability sorting:Golden Camellia Park(6.70)>South Lake Park(6.50)>Flower Park(6.39)>Wuxiang Lake Park(6.20)>Lion Mountain Park(5.97)>Nakao River Wetland Park(5.58)>Folk Song Lake Scenic Spot(5.51)>Shimen Forest Park(5.49)>People's Park(5.30)>Fengling Children's Park(4.89)>Jiangnan Park(4.42)>Guangxi Medicinal Botanical Garden(4.30)>Xinxiu Park(3.85)>Qingxiu Lake Park(3.76).(3)The safety evaluation of Nanning city park is"general",the accessibility evaluation is"poor",the effectiveness evaluation is"good"and the service evaluation is"poor",and the overall evaluation of shock absorbance and disaster mitigation suitability is"general".Nine parks reached level ?,with general suitability;Five parks are rated ?,with poor suitability.(4)In view of the existing problems,this paper puts forward optimization Suggestions on shock absorbers and disaster mitigation of urban parks in nanning from five aspects:balancing the layout of entrances and exits of the park,increasing the number of large medical centers around the park and emergency facilities in the park,and optimizing the accessibility and connectivity of the road network around the park.
