| Park green space is an important part of the urban green space system,with the function of regulating the ecological balance of the city and carrying the public recreation demand.The rapid development of the city and the continuous growth of the population make people put forward higher demands on the park green space,not only for the quantity but also for the quality.In the context of Xinyang City’s efforts to build a garden city,it is of great significance to improve the suitability of parkland in the central area of Xinyang City to meet the growing demand for recreation and to enhance the overall service level of the city.This paper focuses on the suitability of park green space in the central city of Xinyang,based on the improvement of urban living environment and residents’ recreation needs,and conducts comprehensive research on the development status of park green space recreation function by using GIS spatial analysis,field research and questionnaire survey,focusing on the change of park green space quantity,spatial distribution,recreation type,recreation group,recreation scale and Recreation satisfaction and other basic data.Based on the results of the preliminary research and relevant theoretical support,the evaluation index system for the suitability of park green space in the central city of Xinyang City was constructed by using the hierarchical analysis method,and fuzzy comprehensive evaluation and IPA analysis were conducted.The main work contents and conclusions are as follows:(1)Examining the current situation of recreation function of park green space in the central city of Xinyang,the results show that: the number of park green space increases year by year within the unit area,the spatial distribution of park green space is unbalanced with the population density,and the service scope of existing park green space is limited and serviced of blind spot.Through field research and questionnaire survey,the type of recreation is mainly wild recreation,sports and entertainment,sightseeing and photo-taking;the ratio of male to female recreation groups is not very different,with local tourists and middle-aged and elderly groups over 50 years old,and the scale of recreation is mainly 2-5 people;the overall satisfaction of tourists is high,but there are still 29.3% of tourists who are not very satisfied or very dissatisfied,and there is still much room for improvement.(2)The evaluation index system of park recreation suitability in the central urban area of Xinyang City,which contains four levels: target level,criterion level,element level and index level,was constructed by using the hierarchical analysis method,and the weights and consistency tests were conducted for each index factor.On this basis,the fuzzy comprehensive evaluation method was used to quantitatively analyze the fuzzy objects,and the final evaluation score of park recreation suitability in the central urban area of Xinyang City was 3.456,which was "better".The results show that:(1)The importance and satisfaction of ecological environment are high,which can be maintained and optimized continuously;(2)The importance of health perception is low and the satisfaction is high,so there is no need to invest too much;(3)The importance and satisfaction of recreation behavior and recreation landscape are both low,and can be improved slowly;(4)The importance of support conditions is high,satisfaction is low,need to focus on improvement.(3)Summarizing the problems and analyzing the causes,and putting forward five levels of optimization strategies:(1)On recreation landscape level,optimize the design of optimal design shore barge form,create a coordinated water-friendly landscape,strengthen the plant space enclosure,reshape the characteristic creative landscape;(2)On ecological environment level,focus on rectifying management chaos,improve the environmental awareness of tourists;(3)On recreation behavior level,continue to optimize the spatial layout,reasonable enrichment of recreation activities;(4)On support conditions level,coordinate and strengthen recreation services,focus on optimizing transportation network;(5)On health perception level,continue to ensure health perception and carry out stress relief activities as needed.The above research theoretically enriches the relevant system standards of park green space recreation suitability,practically guides the upgrading of park green space in the central city of Xinyang,and provides some reference for the planning and construction of park green space in other cities. |
