Study On The Plant Landscape Of Sunny Island

The research applied theories about botany, ecology, landscape, planning and design and integrated analysis of overlapping multidisciplinary. The paper synthesized the factors of nature, geography, history and humanity, which analyzed the charicters of plant communities and landscape of the Sunny Island, probed the reason of plant communities and landscape, summerized practice experiment from the excellent communities and discerned the transforming trend of communities. On the basis of the above circumstances, the paper summarized plant features of the Sunny Island, thinked out the optimizing tactics and putted foword the concrete scheme on the regional properties of plant landscape so as to direct the plant landscape optimizing. In the mean time, the reserch result can provide method and idea to the urban green land rebuiding and construct. This research main research results are as follows:1. The artificial woody plant composition of the Sunny IslandThere are 146 kinds of the woody plants vascular altogether Subordinating 33 branches and 70 genus. The gymnosperm has 3 branches 7 genuses 14 species and the angiosperm has 30 branches 63 genuses 132 species. According to the tree type, the ever-green coniferous trees have 3 branches 13 species, deciduous leaf coniferous trees have 1 branch 1 species, deciduous broad leaf trees have 23 branches 35 species, deciduous broad leaf short trees and brush have 40 branches 91 species and the vine plants have 3 branches 4 species. Pinaceae, Salicaceae, Oleacea, Rosaceae, Caprifoliaceae and Aceraceae are the dominant branches of the Sunny Island.The common woody plants are 75 species, in which trees are 48 species and shrubs are 27 species. The the trees of frequency 10% tree tree seed to have 12 kinds. The secondary trees of frequency relative high are less. Trere are only 8 species. The ratio of the arbor to shrub is 1:1.The ratio of the ever green trees to delicious leaf is 1:4. The vertical structure has 3 kinds of structures,that is "arbor-shrubs-grass" " arbor-grass" " arbor-shrubs". The average diameter at chest height of trees is 13.86cm, apeoximate 70% of which are belowl0cm,35% of which are between 10-20cm,5% of which are between 20-30cm,2% of which are above 30cm. The seasonal aspect structure is quite rich. The different plant presents differently at all kinds of examples, such as tree shape,tree posture,leaf colour,flower colour flower date,fruit shape,fruit colour,fruit date,branch colour and bark color so on.2.The analysis on the plant landscape of Sunny IslandAccording to profiles and characteristics of plant communities of the Sunny Island, the plant landscape was divided into natural plant landscape, semi-natural plant landscape and artificial plants landscape. Natural plant community is mainly constituted of the natural communities, which is based on grassland meadow and swamp meadow communities, willow plexus and aquatic plants secondarily, temperate deciduous broad-leaved forest embellished in forest-steppe landscape. It is open space and undomesticated whose features of the manifestation of the beauty of nature. Semi-natural plant landscape is relying on the natural environment and natural plant communities, which is appropriately artificial modification or plant configuration, respecting nature, spellcaster natural communities in the composition and structure. It is performance of the natural beauty of botanical landscape to willow bundles and aquatic plants as the main features in landscape. The artificial plant landscape of woody plant communities upland, mainly of herbaceous plants which are cultivated lacking in natural vegetation landscape characteristics. At the same time, artificial woody plant communities should also consider the ecological function, whose plant configuration meet scenic visitors traffic, space activities of the functional requirements. Different species selection and arrangement styles directly determines the characteristics of artificial plants landscape. During the reconstruction of the concessionaire a few times, the formation of artificial plants landscape subjected to different era plant design idea and formed the various landscape modern plants.3. The evaluation on the plant landscape of Sunny IslandThe paper evaluated the plant landscape in Sunny Island by SD. The general evaluation on the choosed communities is novel,spatial,hierarchical peaceful andbeautiful.Among the nine communities of higher scores, there are tow Natural communities,tow Riparian communities,tow Broad-leaved and Coniferous mixed forests and three Eciduous Broad-leaved forests. The landscape charicters of these communities are space-openning,primary and secondary differentiating,and ababdent lines of the edge, crown cover and high trunk.The evaluation of the samples of lower scores is less abundant, less rhythm, less moving, less clear. Among the 4 species, the landscape view less clear and higher canopy closure or the types of trees is over more and p osition is mixed and disorderly or unsatisfactory growth condition bad vitality got lowest evaluation.All the charicters above reduced the evaluation of the plant landscape.Through the factor analysis, the paper summerized four main factors such as perception factor, space factor, aesthetics factor and entirety factor.4.The landscape architecture charicteristics and optimizing of communities in Sunny IslandThe paper summerized the andscape architecture charicteristics through systematic study on the communities and landscape of the Sunny Island. The nature and the artificial plant landscape is distinct and zonality psilophytes and artificial xylophyte landscape coexistence. The artificial xylophyte community take the indigenous plant primarily and introduced variety auxiliary. The plant landscape manifests the region characteristic. The plant landscape manifests the continuity and the mobility. The four seasons landscape is distinct and the coldly plant landscape characteristic is prominent. In this foundation, proposed the plant landscape optimization strategy. Protects the natural vegetation community, highlights the Sunny Island the region plant landscape characteristic.Footholds zonality communies, imitates the nature, simulates natural community structure, contribute the community to the natural succession. Directed the exotic to carry on the disposition suitably, rich community structure and function to enhance plant disposition artistry and landscape ornamental. Further consummated the winter plant landscape and prominents coldly plant landscape characteristic.
