Abstract

Abstract:

To improve the level of planting arrangements, the landscape was quantitatively analyzed from canopy lines and color of plant communities. 3 residential green spaces were selected to measure the fractal dimension of canopy lines and the information dimension of color. The study revealed that the variation in fractal dimension of canopy lines was large within the same group and the variation was small between different groups in the sample communities. The community landscape formed by the combination of garden buildings and plants had high fractal dimension, and canopy lines entirely formed by plant landscape were continuous and had more natural charm. The variation of the canopy contour at different levels within the community was of great fractal dimension, while the canopy lines with discontinuity and mainly based on buildings had low landscape fractal dimension. The information dimension of color reflected the complexity and non-uniformity of color distribution, and the relatively high dimension was one of the characteristics of garden plant community close to the natural community. The comparison and analysis of the 3 sample communities indicated that the plant species were relatively similar, and the planting arrangements in the samples were monotonous. Therefore, it is suggested to strengthen the development of local plant resources and plant configuration level, so as to build near-natural artificial plant communities.

Key words: fractal dimension, landscape plant, community, canopy line, color
