摘要:

以位于湘东的浏阳大围山国家森林公园阔叶林的林内景观为研究对象,从所拍摄的照片中选取了45张最具代表性的,采用SBE评价法对景观的质量进行评价。把林内景观分解为13个要素,每个要素设置3~4个类目,共计39个景观要素组合。通过相关性分析和归回分析,剔除了相关性小的要素,保留了6个相关性较大的要素。结果表明,林内景观要素对美景度的贡献率依次为平均树高(27.7%)、平均胸径(20.2%)、林分密度(17.3%)、色彩丰富度(16.4%)、枯树倒木(9.4%)、绿视率(9.0%),据此建立了景观美学质量与各景观因子类目之间的多元回归模型。提出了修枝、调整林分密度、清理枯倒断木、增加地被植物等提质改造措施。

Abstract:

In this paper,the forest landscape in broad-leaved forest in Dawei Mountain of Liuyang is taken as the object of study.The author takes 45 landscape photographs and adopts SBE method to evaluate the landscape quality.The landscape elements of broad-leaved forests are broken down into 13 elements.39 landscape elements are obtained together.The thesis takes out low-correlated scenic beauty elements and keeps 6 high-correlated elements through correlation analysis and regression analysis.The author lists the ranking of these 6 high-correlated elements according to contribution rate:average height(27.7%),mean DBH(20.2%),stand density(17.3%),colour richness index(16.4%),dead and fallen tree(9.4%),green rate(9.0%).A multi-factor regression equation for the evaluation was set up.The research result provides theoretical basis for quality estimation and management technology of broad-leaved forest landscape.

Key words: evergreen broad-leaved forest, in-forest landscape, SBE, landscape evaluation, landscape transformation
