寒地农业观光园非农生境植物景观季相色彩量化研究

Quantitative study on seasonal color of non-agricultural habitats landscape in cold regions agricultural sightseeing garden

通过研究寒地城市哈尔滨非农生境人工自然景观最为丰富的植物园中10个景观单元案例,采集2017年植物个体生长季叶、花、果NCS色彩值,分析植物景观单元春、夏、秋三季季相色彩动态持续相遇性特征及植物景观单元周边可抵达不同方位视点下季相色彩量化数据,量化加权评价10个案例,总结适用于农业观光园非农生境植物景观季相色彩设计量化方法。结果表明,10个景观单元季相色彩设计质量后评价量化加权排序为:案例10(35)>案例8(32)>案例9(31)>案例7(30)>案例1(24)>案例4(20)>案例6(19)>案例2(16)>案例5(11)>案例3(9),植物种类观赏性状NCS色彩值丰富度,观赏性状季相相遇性、水平可停留空间多视点有景可观三组量化因子,与植物景观季相色彩质量呈正相关,可作为季相色彩设计量化方法,有效提升农业观光园非农生境植物景观季相色彩设计水平。

Through selected the ten typical landscape units of the botanical gardens with the most abundant artificial natural landscapes in the non-agricultural habitats in Harbin, the NCS color values of leaves, flowers, and fruits in the individual growing season of 2017 were collected, in order to analyze its quantitative characteristics of dynamic duration in spring, summer and autumn. And around the plant cluster plant landscape units could arrive at different quarters of the perspective of the quarterly color quantitative data. From the three levels, the scores of the quarter-phase color quality of the seven cases were assigned to quantitative weighted analysis. It summed the quantified methods for seasonal color design of non-agricultural habitats in agricultural sightseeing garden. The results showed that the quantitative weighted ordering of post-evaluation quality for the quarter-phase color design of ten landscape units was case 10（35）case 8（32）case 9（31）case 7（30）case 1（24）case 4（20）case 6（19）case 2（16）case 5（11）case 3（9）. The richness of the NCS color values of the ornamental species of the plant species, the quarter-phase encountering of the ornamental traits, the level of multi-viewpoints,the three-level quantifiable factors, it was positively related to the quality of the seasonal color of the plant landscape. It could be used as a quantitative method for the design of seasonal colors, which could effectively improve the quality of seasonal color design for non-agricultural habitats in agricultural sightseeing garden.
