基于SBE法的杜鹃景观质量评价

摘要

以杜鹃景观为研究对象,拍摄筛选49张景观照片,采用SBE法对景观质量进行评判.在对杜鹃景观进行景观要素分解(分为9个项目,每个项目2～4个类目,共计28个景观要素组合)的基础上,通过相关性分析和回归分析,剔除与美景度相关性小的要素,保留5个与美景度相关性大的要素,保留要素按贡献率大小依次为主色彩比例(28.3％)、色彩布局(24.4％)、色彩数量(18.2 ％)、主色彩色调(16.6 ％)、残缺斑块(12.5％),并得到杜鹃景观美景度评价模型,研究结果为杜鹃景观质量评价与改造经营技术提供了理论依据.%Forty nine photos of Rhododendron simsii plantscape were selected to carry out scenic beauty estimation (SBE).The key plantscape elements of R.simsii was divided into 9 items,each item was further divided into 2 to 4 sub-items,and totally 28 elements were obtained.Elements with low correlation to scenic beauty were removed after correlation and regression analyses.Five highly-correlated elements were kept:ratio of main color (28.3％),pattern of colorful foliage (24.4％),number of color (18.2％),tone of main color (16.6 ％) and naked patches (12.5 ％).A scenic beauty evaluation model for R.simsii plantscape was established.The results would provide theoretical basis for quality estimation and improving management technology of R.simsii plantscape.
