湖南省森林植物园景观质量影响原因研究

以湖南省森林植物园为研究对象,借鉴SBE法对视觉景观质量进行评价,借鉴SD法对景观特征进行评价。通过相关分析建立有关城市森林公园景观质量的评价模型。景观质量评价结果得出植被、水体及路面或广场对视觉景观质量影响较大;景观特征分析了形态丰富度、美感等8个因子对景观质量的影响,建立模型为SBE=-0.58+0.101X₁+0.139X₂+0.257X₃+0.162X₄+0.113X₅+0.181X₆-0.092X₇-0.108X₈,其中,对景观质量影响较大的因子有形态丰富度、美感和生命力,而空间感和变化性与景观质量呈负相关。综合分析结果得出多样化、植被覆盖度高的景观评价较高,人们更为向往自然、幽静的森林景观,森林公园中杂乱无章的植物对景观质量产生消极影响。

A Study of Influencing Factors of Landscape Quality of Hunan Forest Botanical Garden

Hunan Forest Botanical Garden was taken as the object of study to evaluate the visual landscape quality using SBE method and assess landscape features using SD method. The evaluation model of urban forest park landscape quality assessment was built by using related analyses. The landscape quality assessment results showed that vegetation, water bodies and pavement or square have largest influences on visual landscape quality. And the landscape feature analysis showed the impacts of 8 factors such as morphological richness and beauty on landscape quality, and the model built is SBE=-0.58+0.101X₁+0.139X₂+0.257X₃+0.162X₄+0.113X₅+0.181X₆-0.092X₇-0.108X₈. The factors which have greater influence on the landscape quality include species richness, beauty and vitality, and the sense of space and variation are negatively related to the quality of the landscape. Comprehensive analysis results indicated that the diverse and highly vegetated landscape is evaluated higher, which means that people like to go somewhere natural and quiet in forest park, while the chaotic plants in forest park have a negative effect on the quality of the landscape.
