摘要:

为提高园林植物配植水平,从植物群落林冠线和色彩2个方面对景观外貌进行量化分析。研究选取3处居住区中心绿地,测算样本材料的林冠线分形维数和色彩信息维数。研究发现,所选样本植物群落林冠线分形维数组内变异差别较大而组间较小,样本景观塑造以植物群落为主搭配园林建筑分形维数较高,完全以植物造景林冠线较连续,更具自然韵味,群落内部不同层次植物的林冠轮廓分形维数变异性较大,林冠线不连续且以建筑轮廓线为主的景观分形维数较低;色彩的信息维数体现了色彩分布的复杂和不均匀性,维数较高是园林植物群落接近自然群落的特征之一。3个样本植物种类的雷同性较高,样本内部植物配植的层次和龄级较单调,需加强乡土景观植物资源开发和植物配植水平,以营造近自然人工植物群落。

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.
