广州园林绿地木质藤本景观美景度评价

为量化评价广州市园林绿地中木质藤本景观，将木质藤本景观分成附壁、立柱和悬蔓式，篱垣和栅栏式，棚架式，屋顶和廊架式等4类作为评价样本，拍摄样本照片作为评价媒介，运用心理物理学派的美景度评判法（scenic beauty estimation，SBE）进行评价，并对评判值做标准化处理。结果表明，各类型木质藤本景观的美景度从高到低依次是:附壁、立柱和悬蔓式（0.043 9）、屋顶和廊架式（0.015 1）、棚架式（-0.019 7）、篱垣和栅栏式（-0.036 0）；从色彩、层次、绿视率、植物配置、生长状况等方面对4类木质藤本景观进行分析，归纳出适合不同园林应用形式的木质藤本，为园林绿地中木质藤本的应用提供理论依据。

Scenic Beauty Estimation of Liana Landscape in Guangzhou Green Open Spaces

In order to quantitatively evaluate liana landscape distributed in Guangzhou green open spaces, the liana landscapes were divided into four types: climbing on wall, green column and handing tendril type; fence and barrier planting; scaffolding planting; roof and corridor planting, which were used as the evaluation samples. Pictures of the samples were taken as the medium. One hundred and twenty five people were selected to take part in the evaluation, using the scenic beauty estimation method which belonged to the psychophysical school degree evaluation to carry out the evaluation. The values of evaluation results were standardized. The results showed that the beauty degrees of each type of liana from high to low in turn were climbing on wall, green column and handing tendril type (0.043 9), roof and corridor planting (0.015 1), scaffolding planting (-0.019 7), fence and barrier planting (-0.036 0). Four kinds of liana landscapes analyzed from the aspects of color, level, green rate, configuration, and growth condition, forms that were suitable for different landscape applications were summarized. The results would provide theoretical basis for liana application.
