Research On The Plant Landscape In Winter Of West Lake Scenic Area In Hangzhou City

After years of construction,the basic stability of the West Lake Scenic Area plant communities, and a unique local characteristics have been formed,plant configuration of Hangzhou West Lake is beautiful,such as Viewing Fish at flower harbor park,Lotus in the Breeze at Crooked Couryard park,Orioles singing in the willows park and prince bay park is the essence of Hangzhou green parks and representatives,worth learning and reference.This paper choosed winter landscape of Hangzhou West Lake as the researching object,combining a large number of typical case studies,and analyzed woody plant communities,ornamental characteristics of winter plants,as well as the comprehensive evaluation of plant community landscape,the main conclusion are as follows.1.Investigation and analysis on Plant resources of Hangzhou the west lake Scenic Area,According to the literature references,field research statistical analysis showed that,landscape plants and 104 families 240 genera and 423 species,including 5 families of ferns in 5 genera and 5 species of gymnosperms,7 families,18 genera and 29 species,92 families and 217 genera of plant quilt leaves 389.The upper tree diversity degree is high,shrub layer and herb layer species diversity is low.Analysis of characteristics of winter plants with ornamental ornamental effect,can be divided into,flowering plants,foliage plants,ornamental fruit plants,tree trunk plants,tree gesture plants,bud plant concept view position.On the Hangzhou West Lake winter ornamental plants were classified and summarized,winter has obvious ornamental characteristics of the plants(such as flower,fruit,leaf,gesture) and more than 80 kinds of plants,accounting for the total area within the 19%.2.By screening 9 parks along West Lake in Hangzhou, it selects 40 plant communities with quite obvious winter landscapes for investigation, so as to present the performance of community’s winter landscapes from the plant communities’ ornamental characteristics. In all parks of West Lake in Hangzhou, the ornamental characteristics of plant communities in winter are quite similar. However, due to different proportions of ornamental characteristics in winter among communities, the winter landscapes have a large proportion of appreciating branches and ever-green plants, but the ornamental characteristics of appreciating fruits and flowers occupy a quite small proportion. As communities in some spaces perform quite poor effects of winter landscapes, such as the Long Bridge Park, Lakeside Square, Hidden Mountain Pavilion. Parks applying quite good ornamental characteristics of winter include Gushan Donglu Lawn and Mingshiyuan.3.By applying the SBE landscape evaluation method, it establishes an evaluation model for the winter landscape of plants in Hangzhou West Lake. The established model shows that, the sequence of factors affecting the winter landscape of plants in gardens: quantity of ornamental color>coordination with other landscapes>proportion of green>changes of crown layer> plant morphology>undergrowth vegetation>richness of plant levels>plant layout> canopy density; of 40 samples, 23 SBE values are positive numbers, 17 SBE values are negative values. SBE value fluctuates obviously, the maximum value is 1.562 and the minimum value is-0.892. Judging from above, it can be concluded that,in winter, the quality of plant communities of West Lake in Hangzhou is generally in a good state, but the local development is unbalanced, with quite difference of landscape effects.
