Study On The Colouring Characteristics Of Typical Colourd Leaf Tree Species In Hangzhou

In this paper,for the purpose of exploring the general law of color phenology of color-leafed tree species,firstly,the color space in this area is obtained by color extraction,and the color system is divided into seven periods throughout the year,so as to obtain the period value occupied by different color systems.Then,SBE evaluation and analysis are carried out on the color of tree species in seven periods,and the tree species with the highest comprehensive beauty evaluation,the tree species with the highest beauty in each period and the period with the highest beauty of each tree are obtained,thus providing new ideas for landscape plant allocation in color.At the same time,7 color periods are subdivided into 8 phenological periods,and the frequency of their occurrence in 12 phenological seasons is obtained.According to the frequency of phenological occurrence,the seasonal characteristics are inferred,and the best viewing period is obtained,which provides quantitative suggestions for the best tourism viewing season in this area.In addition,according to the starting and ending time of phenological period and its duration,the relationship among phenological periods was analyzed,and the color-leafed tree species were divided into four categories,thus providing a new model for the collocation of garden plants in phenology.Finally,using the color change of color-leafed tree species in autumn and winter for two years,this paper explores the relationship between color-leafed tree species and meteorological factors,and draws general conclusions.
