Research On The Plant Landscape Of QuYuanFengHe Park In HangZhou

This paper choosed QuYuanFengHe Park of Hangzhou as the researching object, and analyzedwoody plant communities, plant seasonal landscape, plant landscape space, as well as thecomprehensive evaluation of plant community landscape of QuYuanFengHe. According to the analysis,the main conclusions are as follows:(1) There were141species of plants in QuYuanFengHe Park, which belonged to58families and100genera, including5families,9genera,14species of gymnosperm;53families,91genera,127species of angiosperm. The species diversity degree of Tree layer was high, and the species diversitydegree of shrub layer and herb layer was low.(2) Flowering plants in park were more, mainly concentrated in spring and summer. There were27species of spring flowering woody plants and5species of herb,20species of summer flowering woodyplants and17species of herb, and the color was mostly red. The number of summer flowering plant wasfar more than the number of spring flowering plant, so summer plant landscape was prominent. Foliageplants landscape in spring and autumn was relatively abundant, and there were21species of foliageplants in spring and22species in autumn. There are17species of plants with ornamental flower、plantswith ornamental fruit and plants with ornamental trunks. Suggest to increase the number of existingsummer woody flower plants, such as Magnolia grandiflora, Albizia julibrissin, Nerium indicum,Lagerstroemia indica, Hibiscus hamabo, Hibiscus syriacus, Photinia serrulata, etc., to further highlightthe summer plant landscape characteristic of QuYuanFengHe.(3) Basing on the community study, the article sumed up the planting space types and theplanting space forms, and through analyzing different planting space types from the qualitative andquantitative aspects, summarized the general rule and technique to the creation of planting space inQuYuanFengHe Park.(4) Built the AHP model for evaluating plant landscape of QuYuanFengHe Park from theperspective of the visual quality, ecological efficiency and service functions, the outcome of thecomprehensive evaluation index showed that13plant communities were on the first grade,17plantcommunities were on the second, no plant communities were on the third or fourth. The resultillustrated that the quality of plant landscape in QuYuanFengHe was overall in good condition, and itwas developing into the best state.
