Quantitative study on landscape colors of plant communities in urban parks based on natural color system and M‐S theory in Nanjing, China

Abstract

Plant color landscape plays an important role in improving the quality of visual landscapes, regulating the emotion of landscape space, and highlighting the characteristics of urban landscapes. How to reasonably quantify and create rich plant color landscapes to achieve the best visual perception of the plant color landscape at different visual scales, so as to better meet the aesthetic needs of the public, has become a hot and difficult issue in the plant color design and application. Therefore, this article selects four typical urban parks in Nanjing to study the color characteristics of plant communities. The natural color system color card is used to extract plant color data. The color harmony and suitability degree of the plant community and external environment are quantitatively evaluated according to the Moon‐Spencer (M‐S) color harmony theory. The correlation between the chromaticity difference, color harmony, and color suitability of the plant landscape color is strong, whereas that between the chromaticity difference and lightness difference of the plant landscape color is weak. Among the four urban parks, the color harmony is the highest, and the appropriate color is the lowest in Xuanwu Lake Park. In addition, among the 12 selected plant community landscapes, the plant community number A3 in Xuanwu Lake Park has the highest color harmony and D3 in Gulin Park has the lowest color harmony. In short, the quantitative study of the plant community landscape color can provide new ideas for improving the optimal allocation of the plant community landscape color in urban parks.

Urban Landscaping Landscape Design and Maintenance Management Method Based on Multisource Big Data Fusion

“…Fang Kuangnan and Zhao Mengmi selected data from two sources, rural and urban, and proposed a logistic regression model based on multisource data fusion for personal credit scoring. The results of the study show that the prediction effect of the integrated model is better than that of the independent dataset model [ 13 ]. Xiong Lifang and Zhen Feng used Baidu index to obtain user attention data among cities in the Yangtze River Delta and analyzed the temporal and spatial evolution characteristics of cities in the Yangtze River Delta by simulating urban information flow [ 14 ].…”

Colour Preference and Healing in Digital Roaming Landscape: A Case Study of Mental Subhealth Populations

“…Through people’s visual colour, it exerts an influence on perception, emotion, memory, and other emotions, among which the colour of the living environment is closely related to the development of human psychology [ 6 , 7 , 8 ]. Shen et al (2021) and Dupont et al (2017) argued that in a landscape with coordinated colour collocation, people can directly stimulate nerves by feeling the colours of different landscapes, which plays a role in conveying emotion, relaxing the body and mind, and fostering interpersonal communication, and thus has a positive impact on people’s physiological, mental, and emotional health [ 9 , 10 ]. However, most studies in this area focus on the colour function design collocation principle without exploring the construction of roaming landscape scenes and immersive experiences, and thus, the evaluation of the final result is uncertain.…”

Implementation of the visual aesthetic quality of slope forest autumn color change into the configuration of tree species

“…Third, some of the existing plants in the forests that need to be optimized may be replaced, or those forests may be supplemented with the selected tree species 20 , 49 . The different periods of phenological color of various tree species should be considered 19 , 31 , 34 , 35 . Tree species with the same or different colors may exist together in the same discoloration period and also appear staggered during the asynchronous discoloration period.…”

“…The opening days are determined based on the duration of autumn leaves to maximize tourism revenue 33 . In China, slope forest attractions engage a large number of tourists during the colorful autumn period, driving the forest tourism industry 19 , 31 , 34 , 35 . Therefore, the exploration and optimization of the changes in autumn color of slope forests is an important step toward improving the visual aesthetic quality of slope forests 19 , 31 .…”
