In recent years,people pay more and more attention to the development of health,outdoor sports have become one of the new major lifestyles of people,and urban parks have become an important place for people to play outdoor sports.At the same time,China’s urban development has gradually shifted from the stage of brutal growth to high-quality development,and in urban construction,especially urban park design should pay more attention to the actual and guarantee the basic service needs of citizens.For the exploration of urban space,urban planners also pay more attention to the public space of the city to bring people’s experience,experts and scholars combine people’s daily behavior and living environment,and explore the urban park from the perspective of environmental psychology for the physical and mental development of people.On the other hand,the technology of collecting data in urban parks has also been further developed.Domestic pre-design research for urban parks uses methods such as multi-source data to conduct pre-design research for urban parks,which can capture accurate spatial information more efficiently.Pocket parks have become an important place to alleviate the lack of greenery and activity space in urban centers in the contemporary era of tight land space supply in urban centers.There are some pocket parks that do not achieve the expected effect due to some design or use reasons,and some of them have the phenomenon of insufficient vitality.Therefore,this study will select four representative pocket parks from 21 pocket parks in Yuexiu District,Guangzhou City as the research object to study the vitality of urban pocket parks,and the paper is divided into five main parts.In the first part,the research background,research significance,research innovation points and research methodology are described for this paper,and the research technology roadmap is drawn as the research framework of this paper.In the second part,we summarize the relevant researches in the fields of public space vitality,pocket parks and multi-source data in recent years,and point out that the collection of research data on public space vitality has become more and more dependent on the support of multi-source data in recent years,and the scope of the application of multi-source data has been expanding,and a large number of practices have gradually started to be carried out in the design and preliminary research of pocket parks.At the same time,typical cases of pocket parks at home and abroad are presented for research reference.In the third part,four pocket parks of different types are selected to construct a spatial vitality evaluation system.This paper points out three factors that determine the vitality of pocket parks-ornamental demand,ecological demand,and activity demand.Using Baidu heat map and other information gathering tools,we conducted field research and questionnaire survey on four different types of pocket parks in Yuexiu District,Guangzhou City: pocket park ornamental demand,ecological demand,and activity demand.The study proceeds from three aspects,using AHP hierarchical analysis to analyze the data information collated with the information collated by Baidu heat map,and finally to assess the vitality of the four types of pocket parks in Yuexiu District,Guangzhou City.In the fourth part,for the four types of pocket parks,this study analyzes their characteristics from the surrounding areas and parks,and summarizes the advantages and disadvantages of spatial vitality by combining the behaviors of users.For the behavior of pocket park users,we use multi-source data to conduct a tracking survey,based on which the field survey situation of the park is combined with multi-source data to improve the objectivity and rationality of the data analysis.In the fifth part,after quantifying the multi-source data to derive improvement strategies for pocket park design,conclusions are drawn and the shortcomings.
