摘要
为了探索城市行道树的景观状况及其影响因子,以20 a以上生香樟行道树为研究对象,运用美景度评价法(scenic beauty estimation,SBE)和10个行道树景观因子对汉中市香樟行道树进行了美学质量评价和影响因子相关性分析。结果表明:所选择的香樟行道树美景度评价级别为一般,其美景度主要受枝下高、枝叶密度、分枝数量、树下景象等4项景观因子影响。其中,枝下高、分枝数量和枝叶密度对美景度的影响极显著(P<0.01),树下景象因子影响显著(P<0.05)。表明评判者更喜欢分枝高度较低、枝叶浓密、分枝数量较多、树下景象较好的行道树,今后汉中市栽植和管理香樟行道树时可参考此结论。
To explore the alee-tree applied as landscape establishment and influential factors concerned,20a street trees of Cinnamomum camphora were studied regarding their scenic beauty and 10 influential factors for beauty evaluation using SBE(scenic beauty estimation).The result showed that the scenic beauty of these trees is evaluated as general level.The scenic beauty is largely influenced by height of lowest branch,number or branching limbs,density of leaves and twigs,and understory things.The previous three factors are most significantly affecting the scenic beauty(P<0.01)and understory things is significantly affecting the scenic beauty(P<0.05),indicating people prefer low height of lowest branching limbs,dense leaves and twigs and more branching twigs and less understory things with the street trees.
