柳州东堤游园彩叶植物“三维彩量”的研究

以柳州市东堤游园为研究对象，选取10个景观单元作为调查样方，借鉴三维绿量概念与计算方法，提出三维彩量概念，分析了东堤游园彩叶植物的三维彩量，为评价城市彩化的立体指标提供依据。结果表明，东堤游园彩叶植物资源丰富，达47.1%，由于春色叶类、秋色叶类以及新叶有色类植物的应用，春秋季的三维彩量值明显高于冬夏，体现了不同植物配置形式能呈现不同的景观效果；样地间春季和秋季的三维彩化率对比均差异明显。依据其结果，推荐2种优秀的植物景观配置模式。

Tridimensional Color Biomass of Color-leafed Plants in Dongdi Garden of Liuzhou

Ten plant landscape units were selected as evaluation plots in Dongdi garden of Liuzhou. The concept and calculational method of tridimensional color biomass was proposed for the first time by the concept and calculational method of tridimensional green biomass to provide theoretical support and scientific reference for the evaluation index of city color stereoscopic. The results suggested that color-leafed plants in Domgdi garden of Liuzhou were rich, up to 47.1%. Due to the application of spring color leaf, autumn color leaf and new leaves of colored plants, tridimensional color biomass in spring and autumn were higher than those in winter and summer. Plant configuration in different forms can produce different effect of landscape. Tridimensional color ratios between spring and autumn rate were obviously different among evaluation plots. Based on tridimensional color ratio results, two good plant arrangement modes that have some practical significance were recommended.
