| Urban parks,as urban green space and important recreational places for residents,can effectively maintain the ecological balance of the city and promote outdoor communication of residents.With the accelerated process of urbanization,urban land use is becoming increasingly tense.How to optimize the spatial layout of urban parks,give full play to the functions of urban parks,improve the quality of park services and space quality,and coordinate the relationship between urban construction and environmental protection in the limited land resources of cities has become an urgent problem to be solved.At present,there are some problems in Bengbu city parks,such as lack of space attraction,lack of space vitality,limited space carrying capacity.Taking Bengbu city parks as the research object,this paper evaluates the service quality of city parks on the basis of theoretical research,and provides reference for the construction and management of Bengbu City parks in practice.Based On landscape pattern index and Arc GIS spatial analysis method,this paper analyzed the spatial distribution characteristics and service capacity of urban parks in Bengbu City,selected six typical urban parks in Bengbu City to conduct field research and questionnaire survey,and used AVC theory and literature analysis method combined with survey data.Attraction,vitality and carrying capacity are summarized as three dimensions,five aspects and 19 indicators,and the service quality evaluation system of urban parks is constructed;Delphi method,analytic hierarchy process and entropy weight method were used to determine the weight,and the service quality of urban parks in Bengbu was evaluated.Finally,based on the positive correlation between service quality and spatial quality of urban parks,the spatial quality improvement and optimization strategies were proposed.The results are as follows:(1)The spatial distribution of urban parks in Bengbu City is characterized by coreedge imbalance,and the service quality of urban parks in different districts is quite different.Longzihu District,Yuhui District and Huaishang District have lower patch fragmentation,larger patch type area and closer relationship with each other,and there is heterogeneity in Bengshan District;The per capita green area of parks in Longzihu District is much larger than that of the other three districts,but the traffic convenience is lower than that of the other three districts.(2)Based on AVC theory,the evaluation system of service quality of urban parks in Bengbu City was established,which was composed of five impact factors of landscape beauty,environmental comfort,environmental safety,functional requirements and spatial accessibility and 19 evaluation indicators.The functional requirements were the core of service quality of urban parks.(3)Bengbu city park service quality in each dimension of the performance of different indicators,including functional requirements dimension is generally the lowest,spatial accessibility dimension is generally the highest.The comprehensive service quality evaluation results of six typical parks show that: Zhanggongshan Park >Longzihu Park > Hushan Park > Datang Park > Donghai Garden > Central Landscape Green Space of Binhu New Area.The analysis results of five service quality impact factors show that the service quality of Bengbu city parks generally has some problems,such as the attraction needs to be improved,the carrying capacity is insufficient,and the vitality is missing.(4)In view of the service quality of Bengbu city parks,the means to improve the quality of urban park space mainly focus on: space accessibility,plant landscape attraction,regional cultural attraction,recreational space attraction,space vitality,park management,space resources carrying capacity,space facilities carrying capacity,ecological environment carrying capacity and other nine aspects.Figure [34] table[40] reference [102]... |
