Color can give people the most intuitive feeling,and it is most likely to attract people’s attention.In terms of urban greening,color-rich color-leafed plant landscape is an important part of landscape construction.In this paper,through the investigation and study of color-leafed landscape plants with stable color changes,leaf scanning and computer matlab software clustering are used to obtain quantitative color values.The leaf color composition and color attribute characteristics of color-leafed plants are summarized,and color Color chromatography is drawn.The color database of color-leafed plants is preliminarily constructed to explore the application of color attributes of color-leafed plants in color configuration.At the same time,the estimation method of scenic beauty was used to evaluate the monochromatic plants,and the factors affecting the color Scenic beauty of monochromatic plants were selected from the color attributes and individual ornamental elements of plants,and the scenic beauty prediction model was constructed to predict the ornamental effect of introduced and cultivated monochromatic plants objectively.The main findings in this paper are as follows :1.The 141 species of ever-colored leaf garden plants belong to 54 families and 96 genera,including 46 species of arbor,48 species of shrub,6 species of lianas and 41 species of ground cover.In terms of families and genera,there were 16,13,9 and 9species of Aceraceae,Rosaceae,Liliaceae,Gramineae,Luteoceridae and legumes,and29 families had only one species.Among the woody plants,56 species of deciduous trees accounted for 59% of the total tree species,most of which were deciduous trees,44 species of evergreen trees accounted for 41%,most of which were evergreen shrubs.According to the proportion of leaf color blocks,there were 80 monochromatic,56 variegated and 4 double-color leaf plants,accounting for 56%,40% and 4% of the total tree species,respectively.In the comparison of cold and warm,warm colors accounted for 60%,a total of 84 kinds,followed by neutral colors,53 kinds,and cool colors,a total of 4 kinds.2.through the leaf color clustering quantitative scanning and matlab software,summed up the plant leaf color color often attribute feature: 141 kinds of color leaf garden plants mainly divided into three major categories,often monochrome leaf,leaf and double-color leaf spot color,a total of six color,divided into red,orange,yellow,green and yellow,green and purple,distribution on the color wheel 13 hue;In terms of plant species,yellow-green plant species are the most,followed by yellow,red,orange and blue-green plant species,and purple plant species are the least,lacking of blue,cyan and purple plant species.According to the statistics of the lightness and lightness of 141 species of plants,there are 258 species of lightness and lightness,respectively,which are distributed in a wide range,but mainly concentrated in medium and high lightness and lightness.There are few plants with high lightness.The range of lightness is mainly distributed in 21%-70%,and the range of lightness is mainly distributed in 23%-87%.3.on the basis of the hue distribution,the establishment of saturation and lightness of recommended color mapping model,and through to the often color digital color collection of garden plant,plant color quantization into color values,form can be widely used in the plant often color color database,for the design of garden plant color use when choosing plants and color to provide data reference.In plant color configuration,plant collocation patterns were contrastively analyzed from hue contrast(similar color,neighboring color and contrasting color contrast,etc.),lightness and saturation(strong contrast,weak contrast and similar contrast,etc.).Through color data and saturation tography,tree species selection and application were carried out according to the collocation patterns of actual needs.4.The landscape of monomer plants with ever-colored leaf plants was selected for scenic beauty estimation,from color and ornamental characteristics on decomposition monomer plant landscape elements,By using correlation analysis and stepwise regression analysis,the elements that have a significant impact on the beauty of single plant with constant color leaves were selected,and the prediction model of beauty of single plant with constant color leaves.Individual posture,color saturation,color lightness and leaf color type have great influence on the beauty value of plant landscape,indicating that people prefer the landscape with beautiful shape,bright color and single color on the plants with constant color. |
