Four components extracted construct characteristic indices a comprehensive model communities. four showed significant or extremely differences among five SBE grades. From overall trend, grades positive correlation with PC1 (primary adjunctive index), PC2 (color structure property index) PC3 (autumn-color-leafed negative PC4 (intersperse index). RPH (ratio primary hue), RP color), RC (color-leafed RWC warm cool colors), NC (number colors) key factors grade. Overall, RPH, RP, RC, positively influenced values, while negatively seven colors more moderate. be improved creating three types composition: warm-toned dominant type, warm- cold-toned contrast multicolor harmonic type. results reference evaluation, construction
