| Identifying Key Impact Factors of User Satisfactionof Pocket Parks Using Impact Asymmetry Analysis |
| WANG Yan,HU Hong |
| Abstract: |
| Previous studies have concluded that there is a linear
relationship between environmental design and usage satisfaction
in pocket park, and this study applied impact-asymmetry analysis to
compare the non-linear relationship between environmental factors
and overall usage satisfaction of pocket park under different spatial
distribution characteristics in Nanjing. The study found that the
relative importance of environmental factors in pocket parks differed
between construction environments, with the aesthetic design of the
greenery, the pruning of the greenery and the proportion of green
paving being the most important environmental factors affecting
the overall satisfaction to road enclosed, community attached and
natural background pocket park respectively. Most of the important
environmental factors have a non-linear asymmetric influence
on overall satisfaction. Based on the degree of asymmetry, the
importance level of environmental factors in pocket park can be
classified, to prioritize the improvement of environmental quality
in pocket parks. In the future, it is necessary to pay attention to the
level of management and maintenance of pocket park, the quality of
green vegetation design and arrangement, the planning and layout of
public service facilities and the communication channels for users'
suggestions and demands, based on the adoption of differentiated
optimization strategies. |
