Research On The Application Of Plant Landscape Colors In Comprehensive Parks Of Chongqing's Main City

Plant color is the main ornamental feature of the plant landscape.The garden space has dynamic beauty because of the color change of the plants in the four seasons.Therefore,the study of plant color had becomed a new research direction in recent years and has attracted more and more attention from researchers.In this paper,we continued to investigate and took photos of the four season colors of common garden plants and plant landscapes in comprehensive parks in Chongqing.We used RHS color cards and Adobe photoshop,color impact and other software to extract plant color attributes and analyze color attributes according to the HSB color model.At the same time,the AHP-GARP evaluation method is used to evaluate the colors of different plant landscapes,and the high-quality plant landscape combinations are selected and the color composition is studied.The main conclusions of the study are as follows:(i)A total of 82 species were used in comprehensive parks in the main urban area of Chongqing,belonging to 51 families and 72 genera.Among them,there were 35 species of trees,24 species of shrubs,19 species of herbs,and 4 species of grasses.There were 24 species of foliage plants,13 species of yellow foliage plants,9 species of red foliage plants,3 species of bicolor foliage plants;40 species of foliage plants,and 19 species of red foliage plants Species,7 species of yellow flowering plants,8 species of blue and purple flowering plants,and 10 species of white flowering plants.There were 8 species of fruit viewing plants,1 species of red viewing fruit plants,2 species of yellow viewing fruit plants,5 species of blue and black viewing fruit plants;9 species of viewing stem plants,1 species of red viewing stems,and green There were 3 kinds of branches,2 kinds of white branches and 3 kinds of black branches.(ii)The HSB color model can be used to obtain the four-season color characteristics of garden plants commonly used in comprehensive parks in the main urban area of Chongqing.There were 9 colors in spring and autumn,followed by 8 in summer and 7 in winter.Among them,the spring plants are mostly yellow-green,medium saturation,and medium brightness.The spring grass and flower plants have a wide variety of colors and rich colors,showing the beautiful landscape of hundreds of flowers in bloom;summer plants are green,medium saturation,and medium brightness.Mostly,the color feels neutral,subtle,far-reaching,and calm;autumn plants are mostly yellow,high-saturated,and moderately bright.The colorful autumn leaf color plants are the focus of autumn and the main body of seasonal landscapes;winter plants Most of the colors are orange,medium saturation,and lightness.Many deciduous plants have thousands of branches and postures,but the colors are dim.In winter,most of the deciduous plants are morphological,not color.(iii)Used the AHP-GRAP comprehensive evaluation model to comprehensively evaluate the application of plant landscape colors,and obtain the criteria layer factor weight ranking as follows: plant landscape color matching> plant landscape color types> plant landscape color attraction> plant landscape color changes> plants The characteristic functions of landscape color,the top three of the index layer ranking are the harmony of plant landscape color matching,the richness of ornamental types of object landscape color,and the layered sense of plant landscape color,indicating that the application of plant landscape color focuses on the color combination of plants and The richness of ornamental types;the color application of plant landscape combination is divided into three levels according to the weighted correlation degree,there were 6 kinds of I grade,37 kinds of II grade,9 kinds of III grade.The weighted relevance of the combined color application of six plant landscapes in level I is 0.800,and its plant color application and configuration mode can be promoted and applied in Chongqing parks.(iv)Used the evaluation method to screen out the color application of high-quality plant landscape combinations,and analyze the color of the high-quality combinations to obtain high-quality plant configuration patterns and plant color matching schemes.The top three plant configurations with weighted relevance degree are Camphor tree-Acer palmatum + Osmanthus + Plum-Gardenia-seasonal flowers,ginkgo + Melaleuca + triangular maple-cherry blossom + red maple + Bauhinia-Rhododendron + heather-grass,plane tree + ginkgo + bayberry-heather + gold leaf privet can be promoted and used.Plant color two-color recommended combinations include yellow and fuchsia,red and green,red and yellow,yellow and green,red and fuchsia,yellow and orange;plant color three-color recommended.The matching combinations are red,yellow and purple,and red,yellow and green.Through analysis,the scheme of plant color matching in Chongqing area is preliminarily summarized,which provides a certain theoretical reference for the color matching of garden plants in Chongqing area.(v)There were still many problems in the application of plant landscape color in the comprehensive park of Chongqing's main urban area,mainly reflected in the uneven distribution of plant color in space and time,and the insufficient variety of spring and autumn foliage plants.In the future application of ground cover plants,more attention should be paid to the rational selection of plant varieties,the optimization of landscape color matching,the ecological benefits,and the maintenance work.
