Blending the stylistic disparities in the two Romanticist poems, Persuasion 's autumnal sensation changes its colors from being tinged with Keats's melancholy to the touch of Shelley's animation. The integration of both tones has created a unique autumnal duet that is remindful of its Romanticist followers.展开更多

The result showed that autumn and winter landscape plants in Kuitun City were primarily evergreen coniferous and deciduous trees outstanding for their shapes and colors, and that landscape was created through different types of plant disposition. Especially colors of trunks, barks, leaves, winter buds and fruits' colors provided favorable conditions for appreciating plants in autumn and winter. Finally, suggestions were proposed according to the investigation and analysis of autumn and winter ornamental plants in Kuitun City, so as to provide reference for future construction and development of landscape plants.展开更多
