With the advancement of the construction of beautiful countryside, the rural plant landscape has gradually become an essential element in the construction of rural aesthetics. Taking Fushan Village in Lishui District, Nanjing, as an example, this paper established a plant landscape color database based on nine spatial types and constructed three systematic evaluation systems of visual quality, consciousness energy, and emotional connection from the spatial types. This was combined with the evaluation outcomes predicted by the multiple linear regression model, and the coupling and coordination relationship of the three systems was analyzed. The results showed that the comprehensive evaluation index of service production space in winter was the highest (17.51), while that of agricultural production space in summer was the lowest (6.75). The coupling coordination degree of each kind of space showed significant differences in different seasons, showing a trend of first decreasing, then increasing, and then decreasing. The level of coupling coordination in autumn and winter is higher than that in spring and summer. Overall, all three systems of plant landscape coloration in Fushan Village exhibited significant seasonal and spatial variations, which should be paid attention to. This paper provides a new perspective for promoting the sustainable development of Fushan Village public space and exploring the field of plant landscape color research in domestic rural public space in the future.
