摘要：为了揭示影响深圳城市森林林外近景观的主要因子,探究其影响群落林外近景美景度的程度,在前期研究的基础上,运用美景度评价法(SBE)对深圳市不同类型城市森林在不同季节的林外近景观进行景观评价。结果表明:1)深圳市城市森林林外近景观以春季美景度值最高,秋冬季的美景度值最低;森林群落以毛棉杜鹃+浙江润楠+亮叶冬青群落的美景度值最高(SBE值=1.071),柠檬桉群落的林外近景观美景度最低(SBE值=-0.641)。2)深圳市城市森林林外近景观主要受色泽明度、色彩丰富度、斑块格局和林龄等因子影响,其美景度拟合模型为SBE=-0.530-0.144X_(5)+0.208X_(7)+0.278X_(8)+0.088X_(16),这4个构景要素可以解释林外近景观美景度值近58.3%的变异。基于研究结果,针对深圳市城市森林美景提升与优化,建议将一些彩叶树种、观花植物相对集中营建,形成大尺度的片林景观;从木本花卉占比、色彩系列及空间格局、游客体验等方面,结合功能分区逐步提高森林景观品质。
With a view to revealing major factors affecting the out?forest landscape of urban forest in Shenzhen,the paper uses the scenic beauty estimation(SBE)method to assess the out?forest landscape of different types of urban forests in different seasons based on the previous studies.The results show that:1)The SBE values of out?forest landscapes are the highest in spring while it is the lowest in winter,and the Rhododendron moulmainense+Machilus chekiangensis+Ilex nitidissima communities have the highest SBE value(SBE=1.071),while the SBE value of Eucalyptus citriodora communities is the lowest(SBE=-0.641);2)The out?forest landscape of urban forest in Shenzhen is affected by the factors of colour brightness,abundance of color,distribution patterns of plaques and forest ages,and the SBE simulation model for the out?forest landscape factors is the SBE=-0.530-0.144X_(5)+0.208X_(7)+0.278X_(8)+0.088X_(16).These four factors significantly explain 58.3%of variance in SBEs.Based on the results,the suggestions are put forward for improving urban forest SBE and optimizing forest management,which include concentrated planting of color?leaf plants and ornamental flower plants to form large?scale forest landscapes,and gradual improvement of forest landscape quality in combination with functional partitions and with consideration of woody flower proportion,color series and spatial pattern,and tourist experience.
