长春市高校植物秋季色彩调查与NCS量化研究

为深入了解高校绿地的秋季植物色彩属性与应用现状,对长春市5所高校主要园林植物进行了秋季色彩调查与量化分析。结果表明,长春市5所高校主要园林植物共计161种,分属51科100属,秋季主色调NCS值范围为S0300-N^S3050-R70B,共8个色系97个NCS标准色,青绿、黄绿、黄色和红色系为主色调的植物种类居多,其中青绿和青黄色等中性色植物共90种,整体温度感较弱;植物色彩的明度和彩度范围较大,多数植物为中、高明度和彩度;主要秋色叶植物色彩变化有变黄和变红两种趋势,其最佳观赏期在10月10-20日;目前橙红色系、蓝紫色系植物种类较少,建议增加此类植物应用;恰当地选择植物种类,均衡不同色系植物色彩NCS值,可以更好地呈现季相色彩与景观变化。

Investigation and NCS Quantification of Plant Color in Autumn in the Campus of Five Universities in Changchun City

In order to know more about the color attributes and applications of plantscape in the university campus in autumn,this study conducted autumn color survey and quantitative analysis about the main ornamental plants in 5 universities in Changchun.The results showed that the autumn colors of the main plantscape in the university campus included 161 species totally,belonging to 51 families and 100 genera.The NCS values ranged from S0300-N to S3050-R70B,there were 8 color schemes and 97 NCS standard colors,green,yellow-green,yellow and red mass-tone were in the majority of plant species.There were 90 plant species in neutral colors such as green and yellow-green,so the overall temperature sense was weak.The ranges of lightness and chromaticity of plant colors were large,most plants were in medium or high lightness and chromaticity.The main autumn plant leaves had yellow and red changing trends,the best viewing period was during October 10-20.At present,the species of orange-red and blue-purple plants were less,so it was suggested to apply more of them,to select appropriate plant species,balance the NCS value of different color systems,to present better seasonal phase colors and landscape changes.
