摘　　要：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 the urban landscape ecological forest in Hefei, evalua- tion model for estimating the relationship between scenic beauty and different landscape elements was established by scenic beauty estimation and multiple linear regression analysis. The results show that the model fits a normal distribution; the value of scenic beauty of urban landscape ecological forest is generally below 1.2 in Hefei; the proportion of br0adleaf trees, average diameter at breast height, the average crown, the proportion of colored tree, lawn cover degree are the dominant five factors according to the influence order to the effects of scenic beauty of urban landscape ecological forest.
