Relationship Between the Landscape Structure of Urban Green Spaces and Residents’ Satisfaction: The Case of a Central District in Hanoi (Vietnam)

Thi-Thanh-Hiên Pham, Dong Chen He, Denis Morin


In urban planning, it is crucial to develop our understanding of human preferences for green spaces in order to maintain and
develop them more efficiently and effectively. However, the research available on this issueis limited to developing and tropical countries. In this study, we investigated the relationships between residents’ satisfaction with green spaces in their neighbourhoods and the landscape structure of green spaces in Hanoi, where intensive transformations in built environment are threatening the existence of green spaces and hence the quality of life. Data on the satisfaction levelsof residents were obtained from a governmental survey. Vegetation classes were identified from a QuickBirdimage by applying object-oriented classification. We then computed landscape metrics for street-side trees and all trees. The results confirmed that people were more satisfied in areas
where 1) all trees were more abundant, well-connected and of variable sizes; and 2) street-side trees were of considerable size and complex canopy shape.These findings are consistent with similar studies in Western countries, at an even higher degree, and underscore the urgent need to plantmore trees along the streets of the Old Quarter in Hanoi and along the Red River banks.
