摘要
A high-grade green space environment will provide necessary environmental support to the outdoor activities of disadvantaged groups including the elderly and is thus helpful for promoting their physical activity level and life quality.This paper takes the urban area of Dalian City as an example and divides the external environmental characteristics of a green space into three aspects including the diversity degree of facilities,the richness level of street functions,and the mixing degree of land use.Based on the data of a survey on activities by elderly in green space,the paper conducts an in-depth study on the statistical correlation between the external environmental characteristics of green space and the frequency of use by the elderly.The study shows that diversified facility types around a green space are conducive to a rise in the frequency of use of this space by the elderly,out of which the effect of functional facilities such as school and food market is the most significant.In addition,being adjacent to streets full of daily life or being mixed with residential land use will increase the frequency of use of the green space by the elderly.This paper puts forward certain environmental upgrading strategies for green space from the perspective of external environmental characteristics in order to help build up green space that is use-friendly to the elderly.
