安徽省九华山风景区古树群落景观美学评价

Landscape aesthetic assessment of old-tree communities in Jiuhua Mountain Scenic Area of Anhui Province

以九华山风景区古树名木群落为研究对象,收集了26个有代表性古树群落和45个对比林分的景观图片和样地资料,采用美景度评判法获得美景度值。利用语义差别法对古树群落的景观要素进行量化,并运用多元线性回归建立美景度值与景观要素的模型。结果表明:古树群落美景度值显著高于其他对比林分;受测者对景区内古树群落树木排列、光感、树木大小变异等景观要素反应值较高;树木形态、色彩丰富度、树木排列、林下层统一度、层次感、自然整枝、乔木层枝叶统一度是影响古树群落景观质量的主要要素,F检验表明,通过这些景观要素建立的模型是合理可行的。

Taking the old-tree communities in Jiuhua Mountain Scenic Area as the object,the landscape photos and sampling plots information of 26 representative old-tree forest stands and 45 contrast forest stands were collected,and the scenic beauty values of the stands were acquired by using scenic beauty estimation（SBE） method.The landscape elements of old-tree communities were quantified by semantic differential（SD） method,and the relationships between scenic beauty values and specific landscape elements were evaluated with multi-regression model.The old-tree communities had significantly higher scenic beauty values than the other forest stands.In old-forest stands,the test trees had higher feedback values to the landscape elements such as arrangement of trees,light perception,and variation of tree size.The main elements affecting the landscape aesthetic value of old-tree community were the trunk form,richness of color,arrangement of trees,uniformity of ground plants,landscape gradation,natural pruning,and uniformity of shoots and leaves in tree layer.F-test showed that the model established by these landscape elements was reasonable and feasible.
