Color Evaluation Of The Full Bloom Flower Bed In The Comprehensive Park In Main City Zone Of Chongqing

The full bloom flower bed is an important form in modern gardens.Its application is very extensive,it can be seen in the green areas of parks,both sides of roads,green areas in residential areas,and green areas of squares.Plants are an important part of the landscape of the full bloom flower bed,and the overall beauty and magnificent beauty of the full bloom flower bed can be displayed through the color,shape and modeling of plant combination.When viewing the full bloom flower bed,the thing that most stimulates human vision is the color of the flower bed.Therefore,this article studies the full bloom flower bed according to the chromatics.In this article,the RHS colorimetric card method and the color impact software color extraction method were used to extract the color of the plant.At the same time,the SBE evaluation method was adopted to evaluate the beauty degree of 91 plants of the full bloom flower bed and 60 groups of the full bloom flower beds in the comprehensive park in main city zone of Chongqing.Moreover,a color element-beauty degree evaluation model was established.On this basis,the color matching methods and typical color matching modes of the full bloom flower bed were summarized.The main contents and conclusions of the study were as follows:(1)Among the existing plant main color extraction methods,RHS plant colorimetric card and Color Impact software color extraction method were selected to extract the color of the plant in the full bloom flower bed.(2)The full bloom flower bed in the comprehensive park in main city zone of Chongqing were investigated.According to statistics,there were a total of 60 groups of full bloom flower beds and 91 kinds of plants.And they were mainly herb plants and a small number of bush plants.Compositae had the largest variety and number,there were a total of 26 species.The most frequently used plants were Celosia cristata and Chrysanthemum.(3)Ninety-one kinds of plants in the full bloom flower bed were subjected to color investigation and color analysis,and the RHS value of each plant was obtained and sorted according to the color type.(4)Sixty groups of the full bloom flower bed were subjected to color investigation.From the perspective of color matching and cold and warm color matching,the color was analyzed,and the color matching of the full bloom flower bed in different functional spaces was analyzed.(5)Through the SBE evaluation method,91 plants and 60 groups of the full bloom flower beds were evaluated and ranked.Among them,the plant with the highest SBE value was Plumbago auriculata among single plants,the valuewas 1.1.Among the flower bed combinations,the combination with the highe st SBE value was Z7 combination(Salvia splendens Ker-Gawler+Dendranth emamorifoliumcv.'pompon'+Rhododendron simsii Planch+Sedum lineare Thunb+C hamaedorea elegansMart+Pteris ensiformis Burm+Coleus blumei+Codiaeum varie gatum+Cordyline fruticosa+Ligustrum lucidum+Callistephus chinensis+Catharanthu s roseus),the value was 1.06.(6)The color elements of the full bloom flower bed were divided into 14 color factors,and the color element-beauty degree model was established:SBE=-1.784+0.106X4+0.274X6-0.080X7+0.129X8+0.092X9+0.089X13-0.171X11+0.018X10.(7)The influence of the single color element on the beauty degree was analyzed and the model was established:(1)The fitting model between the bright sense of the color and the beauty degree was:SBE=-1.981+1.473x-0.271x2.(2)The fitting model between the sense of cold and warm color and the beauty degree was:SBE=-1.182+1.32x-0.341x2.(3)The fitting model between the highlight degree of the color clumps and the beauty degree was:SBE=-0.276+0.173x-0.034x~2.(4)The fitting model between the contrast degree of the color and the beauty degree was:SBE=-0.407+0.306x-0.06x2.(5)The fitting model between the flowering number of flower beds and the beauty degree was::SBE=-0.845+0.158x+0.012x~2+0.005x~3.(6)The fitting model between the total number of flower bed plants and the beauty degree was:SBE=-0.957+0.185x-0.003x2.(7)The fitting model between the green proportion and the beauty degree was:SBE=-0.264+2.014x-2.902x~2.(8)The fitting model between the proportion of the main color and the beauty degree was:SBE=-0.364+0.061x-0.003x~2+0.02x~3.(8)Summary of the plant color matching methods of the full bloom flower bed:The overall color of the flower bed should be bright and biased toward warm tones;The highlight degree of the color clump should be determined by the number of actual colors of the flower bed.When the number of colors was greater than 5,the highlight degree of the color clumps should be obvious.On the contrary,it should be blurred;The contrast degree of the color of the flower bed should be obvious,the flowering number of the flower bed should be controlled at 3 to 5 kinds,and the flower bed plant should be controlled at 4 to 7 species;The proportion of green plants should be 20%to 30%;The proportion of the main color of the flower bed should be 30%to 60%,the harmony of color type should be determined by the position of the flower bed and the surrounding environment;The hue contrast of the flower bed should be appropriately increased.The layout of the main color should be partial to create an atmosphere of close flowers,such a flower bed was more attractive to tourists.(9)According to the field research and the evaluation of the beauty degree,the typical configuration mode of the full bloom flower bed was summarized.In addition,according to the four seasons of spring,summer,autumn and winter,it was classified.In each season,the flower beds were divided into two categories,they were the similar color matching and the contrast color matching.According to the color,typical matching patterns were summarized.
