厦门市风景林春季植物景观质量评价初探

Preliminary Study on Quality Evaluation for Spring Plant Landscape of Landscape Forest in Xiamen

以厦门风景林春季植物景观为研究对象,收集65张近景植物图片和相关资料,采用大众评判法获得美景度,运用多元数量化模型Ⅰ,依据美景度与景观要素的关系建立观花类与非观花类评价模型,实现厦门市风景林景观质量的评价。结果表明:影响春景观花模型的主要因子顺序是绿色比>非景观影响因子>灰度比>色彩布局>林冠层变化,各因子的偏相关系数均在0.88以上,复相关系数达0.97;影响春景非观花模型的主要因子顺序是绿色比>林冠面特征>非景观影响因子>生活型特征,偏相关系数均在0.87以上,复相关系数达0.99。

Taking the spring plant landscape of landscape forest in Xiamen as a study object, a total of 65 representative photos of near-view landscape and related information were collected. The scenic beauty value was acquired by public judgment method, and the evaluation model for flowering ornamental landscape and non-flowering ornamental landscape was established about the relation of scenic beauty value and landscape element by multiple mathematical model I, then, the landscape quality evaluation of landscape forest in Xiamen city was carried out. The results showed： in the model for flowering ornamental landscape in spring, the main gene and the order of the influence on the landscape quality was green ratio 〉 non-sight impact factor 〉 gray intensity ratio 〉 color layout 〉 change of canopy layer with the partial correlation coefficients being above 0.88, and the multiple correlation coefficient of the model reached 0.97 ; and in the model for non-flowering ornamental landscape, the main gene and the order of the influence on the land- scape quality was green ratio 〉 canopy character 〉 non-sight impact gene 〉 character of life form with the partial correlation coeffi- cients being above 0. 87, and the multiple correlation coefficient of the model reached 0.99.
