上海环城林带植物群落景观美学评价

以上海环城林带为对象，采用美景度评判法进行不同植被类型的景观评价，评价分为林内景观和林外景观2个空间层次，分别在春、夏、秋、冬4个季节进行。结果表明，林内景观平均值和林外景观的美景度都表现为夏季最高，冬季最低。在不同植被类型的林内景观中，落叶针叶林在不同季节均表现出最高的美景度，竹林的美景度最低；针叶林中，常绿针叶林的美景度四季均低于落叶针叶林；阔叶林中，落叶阔叶林的美景度在春季和夏季高于常绿落叶林，常绿阔叶林在秋季和冬季高于落叶阔叶林；混交林中，除秋季外，针阔混交林的美景度均高于常绿落叶阔叶混交林。

Aesthetic Evaluation of Typical Plant Communities in Green Belt around Shanghai

The landscape evaluation of different plant communities in the green belt around Shanghai was conducted in spring, summer, autumn and winter. The in-forest and outer-forest landscapes were evaluated with the scenic beauty estimation （SBE） method. The results showed that average SBE values of in-forest and outer-forest landscapes were both the highest in summer, and the lowest in winter. The in-forest SBE values of deciduous coniferous forests were the highest in all four seasons among different vegetation types, and SBE values of bamboo forest were the lowest. Among the coniferous forests, the SBE values of evergreen coniferous forest were lower than deciduous coniferous forest in all four seasons. Among the broad - leaved forests, the SBE values of deciduous broad-leaved forest were higher than evergreen deciduous forest in spring and summer, but reversely in autumn and winter. Among mixed forests, except for autumn, the SBE values of broad-leaved and coniferous mixed forest were higher than evergreen and deciduous broad-leaved mixed forest.
