ABSTRACT: The purpose of this study is to quantitatively analyze the relationship between green plant allocation and visual health of underground street space.In this paper, from the perspective of environmental psychology, 40 subjects were asked to observe 10 scenes, and the SBE method and intelligent interactive eye movement experiment were used to study the effects of green plants on the visual health of underground space.The results show that the presence of green plants can obviously improve the visual health of underground street space.The effect of green plants on visual health of underground space is very different from that of aboveground space. The optimal green visual rate of underground street is about 8%, which is much lower than that of aboveground street.When too many green plants are too large, the visual health of underground street will decline obviously.The results indicate that attention should be paid to the layout design of green plants when improving the visual health of underground streets.
