“…However, previous studies have found that the quality of community landscapes in a group was higher than uniformly and randomly distributed landscapes [46]. However, when investigating the degree of aggregation of landscape color patches, it was found that excessively gathered color patches may negatively affect the emotional state of people, but landscapes with more color patches are more likely to be favored by observers [32,47]. On the other hand, a colorful, attractive street edge may distract drivers, which could lead to more accidents than the "monotonous" green landscapes.…”

Landscape color provides visual attractiveness and is an important landscape architecture construct in design and with aesthetics. Along roadways, plant color in a midground position provides a potential location readily seen by people. However, few studies have quantitatively explored the impact of a green (original) only compared to additions of color on the visual aesthetic quality (VAQ) in this spatial location. In this study, visual images were constructed to contrast four red color proportions (25%, 50%, 75% and 100% of midground) and four color spatial distributions (Red-Single, Red-Group, Green-Single and Green-Group) mixed with three landscapes texture classes (rigid = narrowleaf coniferous, soft = broadleaved, and mixed = both) in the background. As red color proportion increased, VAQ also increased. In the original all green landscape, the background setting had a significant impact on VAQ, but the texture plant design of the foreground had no significant impact on the landscape VAQ. Broadleaved (M VAQ = 63.2) and coniferous landscapes (M VAQ = 55.9) were rated as more attractive than a mixed landscape (M VAQ = 27.9). From the perspective of design color, increasing the proportions of color can improve the VAQ of the landscape. This study indicates that aesthetic quality becomes highest when the color proportion of the middle ground layer was greatest at C 100 (M VAQ = 79.7). Comparing the four spatial color distributions, the single distributed green landscape (M VAQ = 60.9) and the group distributed landscape when started with red (M VAQ = 54.0) had the higher quality than the others. Findings from this study can be used to support public authorities and urban planners to effectively design and manage urban spaces to meet dwellers' needs.Visual aesthetic quality (VAQ) is an index to potentially rate USG [9][10][11] and use by decision makers to design and install landscapes that link people and nature [12,13] and best express people's preferences for landscapes. Most VAQ research comes from landscape studies on agriculture [14], architecture [15], and rural forestry applications [16]. Thus, testing the application of VAQ models into UGS provides another land use to explore the application in built environments.Vegetation imparts aesthetics through color, texture, and form [17]. Other vegetation features, such as the tree stand age and horizontal structure, also show some significant influence on quality [18]. Color is an important element of visual perception and evaluation [19,20] and as much as 80% of people's visual perception comes from color [21]. Thus, vegetation color is an important factor to evaluate and measure to index landscape beauty [3]. Understanding human preference for the color can lead to more attractive UGS through the impact of color on visual beauty.Many studies have shown that plant color is an important factor affecting people's evaluation [6,[22][23][24], but these studies mainly focus on the color change of individual tree parts, such as the leaf [25,26] and flower [27] of a...

Contemporary landscape architecture studies have paid close attention to the interactions between public aesthetic preferences and the landscape environment. Scenic beauty has become an important evaluation indicator of landscape quality. The quality of the plant color landscape is an important factor affecting scenic beauty. Exploring the relationship between the composition rules and internal properties of autumn plant color landscapes in urban parks and public aesthetic preferences can provide new ideas for the evaluation and design of plant community color landscapes. Taking 12 parks in Changsha City, Hunan Province, China, as the study area and 85 plant communities as the sample plots, scenic beauty estimation (SBE) was used to evaluate the autumn plant color landscape of urban parks. ColorImpact software was used to extract the color values of each plant community. Fifteen original color element indicators were determined, and the data were statistically analyzed by principal component analysis (PCA), one-way ANOVA, multiple comparison analysis and systematic cluster analysis. Four principal components were extracted to construct the characteristic indices and a comprehensive model of the color landscape quality of autumn plant communities. The four characteristic indices showed significant or extremely significant differences among the five SBE grades. From the overall trend, the SBE grades showed a positive correlation with PC1 (primary and adjunctive color index), PC2 (color structure and property index) and PC3 (autumn-color-leafed index) and a negative correlation with PC4 (intersperse color index). RPH (ratio of primary hue), RP (ratio of primary color), RC (color-leafed index), RWC (ratio of warm and cool colors), and NC (number of colors) were the key factors affecting the SBE grade. Overall, RPH, RP, RC, and RWC positively influenced the SBE values, while NC negatively influenced the SBE values, and five to seven colors were more moderate. The quality of the color landscape can be improved by creating plant communities with three types of color composition: warm-toned dominant type, warm- and cold-toned contrast type, and multicolor harmonic type. The results provide a reference for the evaluation, design and construction of autumn plant color landscapes in urban parks.
