摘要:
以杭州西湖47处植物群落为研究对象,从秋色叶色域面积占比和美景度评价(SBE法) 2个方面对西湖植物群落的美学质量进行研究。结果表明:(1)评价人员对于西湖秋季植物景观总体持积极的态度;(2)秋色叶色域面积与植物群落总面积的比值分布范围在0 ~ 0.8之间,较为分散;(3)秋色叶色域面积占比大于0.5的群落数量较少,仅占总数量的36%;(4)秋色叶色域面积占比接近0.4或0.7时,群落景观的SBE值最高。通过对西湖秋季植物群落中秋季色彩进行量化研究,为亚热带地区的秋季植物景观的配置方式提供一定的指导。

Abstract:
Taking 47 plant communities of West Lake in Hangzhou as the research object, the aesthetic quality of the plant communities in the West Lake was studied from two aspects: the proportion of autumn leaf color gamut area and scenic beauty estimation (SBE method). The results were as follows: (1) On the whole, the evaluators held a positive attitude towards the autumn plant landscape of West Lake; (2) The ratio of the color gamut area of autumn leaves to the total area of the plant community ranged from 0 to 0.8, which was relatively dispersed; (3) The number of communities with leaf color gamut area ratio greater than 0.5 in autumn was less, accounting for only 36% of the total number; (4) When the color gamut area ratio of autumn leaves was close to 0.4 or 0.7, the SBE value of community landscape was the highest. A quantitative study on the autumn leaf color in the autumn plant community of West Lake was carried out to provide some guidances for the configuration of autumn plant landscape in the subtropical region.
Key words:  plant community  color gamut area ratio of autumn leaves  SBE  West Lake in Hangzhou
