| As an intuitive visual perception,color plays an important role in the construction of landscape environment.On the one hand,it affects the landscape effect by stimulating the visual sense organs,and improves the landscape effect by matching the landscape color.On the other hand,by stimulating the psychological senses to foil the landscape artistic conception,through the creation of landscape color to foil the landscape atmosphere.Therefore,quantitative research is more scientific for exploring the characteristics and laws of landscape color.Based on HSB mode,on the basis of quantifying color language,through the establishment of systematic color investigation and research methods,this paper analyzes the typical regional landscape color in the Sui and Tang Dynasties City Ruins Botanical Garden,and summarizes its seasonal changes and the variation of diversity.A total of 3712 groups of landscape color were collected through the investigation of 16 typical areas in the park,including 997 groups of spring landscape color,916 groups of summer landscape color,916 groups of autumn landscape color and 883 groups of winter landscape color.The conclusion shows that the landscape color changes obviously with the season.In quantitative analysis,based on HSB data analysis,it is found that the natural color hue of landscape color changes significantly with the season,mainly from the change of plant color.With the seasonal change,the change of plant morphological characteristics directly affects the change of color.In the aspect of color saturation,the color change of winter landscape is significant,mainly low color saturation,while the other three seasons mainly focus on medium color saturation.In the aspect of color brightness,the overall change is not significant,basically maintain the medium brightness color mainly.In the aspect of diversity analysis,based on Shannon-Wiener index,it is found that the richness of landscape color is affected by the richness of landscape elements on the one hand,and the regions with more landscape elements are also richer in the corresponding landscape color.On the other hand,influenced by seasonal changes,the richness of landscape color showed a decreasing trend from spring to winter.The study of Dominance index shows that,on the one hand,the landscape color is affected by the proportion of each landscape element.The landscape color also shows obviouschanges.The proportion of each landscape element is balanced,and its landscape color is relatively balanced.On the other hand,affected by seasonal changes,through the growth of plants,the dominance of landscape color changes.With the richness of plant growth,it directly affects the color proportion of hard landscape,water body and plants and other major landscape elements.By exploring the relevant characteristics of landscape color,it can provide some theoretical guidance for plant collocation and application as well as the construction of landscape environment,and provide new ideas and new ways for future landscape planning and design. |
