济南城市公园植物景观色彩分析

Analysis of Plant Landscape Color of Urban Parks in Ji’nan

植物色彩是城市公园的重要视觉要素之一,有着丰富的季相变化。在NCS自然色彩系统的基础上,通过对济南城区4座主要城市公园的植物色彩进行数据化分析,调研该地植物季相色彩构成和变化规律。结果表明:济南城市公园中具有色彩观赏价值的植物应用丰富,春、夏、秋三季色彩观赏价值最高;冬季绿色量与非绿色量的比值显著高于平均水平,绿色值总量达到26.4%。提出应放缓常绿树种的引种栽植,增加具有冬季色彩观赏价值的植物;济南城市植物景观色彩规划应以“四面荷花三面柳”为背景色,考虑不同季节植物色彩效果,点缀低明度、中艳度、高彩度的彩色植物。

The color of the urban park plant is one of the important visual elements, with abundant seasonal changes. After analysis of the color information of plants in 4 major urban parks in Ji’nan on the basis of the Natural Color System, the seasonal color composition and changing rules were investigated. The results showed that plants with color ornamental value had abundant applications in urban parks in Ji’nan. The three seasons of spring, summer and autumn had the greatest ornamental value on color;the ratio of the amount of green to the amount of non-green in winter was significantly higher than the average level, and the proportion of evergreen value reached 27%. Therefore, the color appreciation should be enriched in winter, and the planting of evergreen trees should be slowed down in urban parks in Ji’nan. The color planning of landscape in Jinan should take the “four-sided lotus and three-sided willow” as the background color, considering the color effects of plants in different seasons, and decorate the color plants with low brightness, medium brightness and high color.
