为了提高城市景观生态林美学质量,以合肥城市景观生态林为研究对象,采用美景度评估法(scenic beauty estimation,简称SBE)和多元线性回归进行综合分析,建立相关线性方程作为评价模型。结果表明:合肥城市景观生态林符合正态分布;合肥城市景观生态林美景度值分布在1.2以下,整体偏低;影响城市景观生态林景观美学质量的关键要素有5个,按影响大小排序为阔叶树比例、平均胸径、平均冠幅、有色树木比例及草坪盖度。
In order to improve the aesthetic quality of urban landscape ecological forest, this paper takes Hefei urban landscape ecological forest as the research object, and makes comprehensive analysis using the scenic beauty estimation (SBE) and multiple linear regression to establish the relevant linear equation as the evaluation model. The results showed that the ecological landscape of urban landscape in Hefei was in accordance with the normal distribution. The scenic values of ecological landscape in urban landscape of Hefei were distributed below 1.2, with a low overall value. There were 5 key elements affecting the landscape aesthetic quality of urban landscape ecological landscape, Broad-leaved tree ratio, average breast diameter, average crown width, proportion of colored trees and turf coverage.
