| After a long period of evolution,urban parks have formed a dynamic space with regional characteristics and spiritual connotations in terms of spatial organization and recreation functions.With the development of society and the proposal of related concepts and construction requirements of "Park City",landscape architecture,as the key engine of park city construction,also faces a new round of opportunities and challenges.The research on the spatial vitality of urban parks in Chengdu can more clearly recognize the methods and strategies of creating vitality with regional characteristics in Chengdu,which is conducive to the renewal of existing parks,as well as the better integration of the construction of new parks into the surrounding environment,in line with the public behavior and psychological needs,so as to improve the utilization rate and spatial vitality of urban parks.The updating of relevant technical means in the data age expands the research ideas of urban park spatial vitality in terms of the breadth,refinement and timeliness of space and time.This paper analyzes the strategies,methods and measures of urban park space vitality construction from the aspects of urban park space vitality construction,revival,evaluation and recreation behavior.The thermal data were used to analyze the urban parks within the third ring road of Chengdu,and the order of thermal values was used to determine the research objects as people’s park,xinhua park,wuhou temple and running water park,considering the workload and operability at the later stage.Through online and offline data,the combination of quantitative and qualitative methods,based on the traditional dynamic factor classification,the vitality of city park space is divided into spatial dynamic space,population distribution density is the external representation of dynamic external cause and internal cause.By means of macro and micro scale can external empty city park facilities,recreation of the internal behavior of time and space,choose factors such as study,environment of various factors on the dynamic analysis of city parks.The main results and conclusions are as follows: first,to construct a framework that can complement the spatial vitality of urban parks and better reflect the comprehensive effect of the park environment on the vitality,multiple factors should be considered from both internal and external aspects.Secondly,the spatial vitality of urban parks under the influence of external factors presents a strong feature of central aggregation,among which the functional density has a significant impact on it.Thirdly,the recreation behavior of urban parks has temporal and spatial rules,and the factors of tourists’ satisfaction,recreation preference and behavior selection are common.Fourth,the comprehensive effect of the internal and external environment of the urban park forms a dynamic space with multiple mixing,internal and external infiltration and rich spatial diversity.Based on open data of urban park space dynamic research,in the aspect of city parks,recreational recreation satisfaction provides more scientific,rigorous,objective research train of thought,on updates and vitality of the city park space plays an important role,can promote innovative methods of planning and design,planning and design thinking and design concept of updates. |
