长沙圭塘河绿道环境对居民休闲体力活动的影响研究

Research on the Impact of the Gui Tang River Greenway Environment in Changsha on Residents' Leisure Physical Activities

城市绿道是重要的绿色基础设施,是为居民提供活动的线性公共空间。以长沙市圭塘河绿道为例,为了促进居民在城市绿道进行休闲体力活动,研究城市绿道环境(景观环境和基础设施环境)对居民休闲体力活动的影响,通过问卷访谈收集了受访者社会人口基本特征、体力活动情况和圭塘河绿道环境变量,运用多元线性回归模型探究圭塘河绿道环境对居民休闲体力活动的影响。结果显示:圭塘河绿道景观环境中植被种类丰富度和层次感与植被景观美感度显著影响居民体力活动水平;圭塘河绿道基础设施环境中休息座椅及观景设施数量和位置与垃圾桶数量与设立位置显著影响居民体力活动水平;进行剧烈活动的居民比进行轻度活动和中度活动的居民对景观环境和基础设施环境需求更强烈。在研究结果的基础上,为促进居民休闲体力活动,提出了城市绿道空间优化的建议。

Urban Greenways are crucial green infrastructure that serves as linear public spaces for residents' recreational activities.Taking the Gui Tang River Greenway in Changsha City as a case study,this research aims to investigate the influence of urban greenway environments(landscape and infrastructure) on residents' leisure physical activities.Data on the socio-demographic characteristics of respondents,physical activity levels,and Gui Tang River Greenway environmental variables were collected through questionnaire interviews.A multiple linear regression model was applied to explore the impact of the Gui Tang River Greenway environment on residents' leisure physical activities.The results reveal that the diversity and structure of vegetation types in the Gui Tang River Greenway landscape significantly affect residents' physical activity levels,as does the aesthetic perception of the vegetation landscape.Additionally,the number and placement of resting seats,observation points,and the quantity and placement of trash bins in the Gui Tang River Greenway infrastructure environment also have a significant impact on residents' physical activity levels.Residents engaged in vigorous physical activities have stronger demands for both landscape and infrastructure environments compared to those engaging in mild or moderate activities.Based on the findings,this study offers spatial optimization recommendations for urban greenways to promote residents' physical activities.
