Traditional seasonal color matching methods of ornamental plants only study the color attributes of plants, but not through qualitative and quantitative research on seasonal color matching of plants, resulting in imperfect matching methods. Five landscape units were selected from five representative streets in Harbin, namely, Central Avenue, Gogoli, Zhongshan Road, Xinyang Road, and Huanghe Road. Seasonal periods of Harbin from 2014 to 2018 were defined using the difference in seasonal time division and duration characteristics by the method of climate temperature division, and the beginning time of each season in 2019 was deduced. Meanwhile, according to the NCS color value data of each species in different seasons and the length of each season, the seasonal color matching results of each landscape unit case were established. The results of seasonal color matching of each landscape unit case were evaluated by weighted method. The results showed that the richer the NCS color value of plant species ornamental traits in plant landscape, the more the color seasonal encounter of ornamental traits and the longer the duration, the better the matching results of plant seasonal color. Based on the research results, the NCS color value and its ornamental period of ornamental characters of plant species, the color matching scheme of landscape color, and the selection of plant species were proposed.

城市景观建设中观赏植物的季节性配色方法

传统的观赏植物季节配色方法只研究植物的颜色属性，而没有对植物的季节配色进行定性和定量研究，导致配色方法不完善。从哈尔滨市5条具有代表性的街道，即中央大街、果戈里、中山路、信阳路、黄河路，选取了5个景观单元。利用气候温度划分的方法，利用季节分时和历时特征的差异，定义哈尔滨市2014-2018年的季节周期，推导出2019年各季节的开始时间。同时，根据各物种不同季节的NCS色值数据和每个季节的长度，建立各景观单元案例的季节配色结果。采用加权法对各景观单元案例的季节配色结果进行评价。结果表明，植物景观中植物物种观赏性状的NCS颜色值越丰富，观赏性状的颜色季节性遭遇越多，持续时间越长，植物季节性颜色的匹配效果越好。根据研究结果，提出了植物物种观赏性状的NCS色值及其观赏期、景观色彩的配色方案以及植物物种的选择。植物季节性色彩的搭配效果越好。根据研究结果，提出了植物物种观赏性状的NCS色值及其观赏期、景观色彩的配色方案以及植物物种的选择。植物季节性色彩的搭配效果越好。根据研究结果，提出了植物物种观赏性状的NCS色值及其观赏期、景观色彩的配色方案以及植物物种的选择。
