| This paper choosed Hangzhou West Lake Gushan as researching objedct,and analyzed the index of plant communities such as the distribution of plant families and genera, the frequency of major species and the important value of main species,and summarized quantitative characteristics of garden plants based on the field survey by community ecology principles; Summarized garden plant community diversity by analyzing the plant community canopy density, vertical structure,and species diversity index,and then analyzed and compared diversity of different life forms of garden plants; Surveyed flower, fruit and other types of plant of each season in Gushan scenic and analyzed the seasonal changes,meanwhile analyzed various types of garden plants landscape space configuration concepts and techniques and Summed up the create Features of the plant space depending on the factors such as the plant configuration Arts and plant enclosed degree and combined with the actual case and drawing a ichnography. The main conclusions are as follows:(1)18 sample area were selected to investigate and each plant was recorded within the scope of investigation and analyzed the composition of plant species. The results of the survey were as follows: Within the scope of the investigation, there were 203 kinds of plants(including varieties and cultivars) belonging to 81 families and158 genera and 203 species,among them, there were 80 kinds of trees, 48 kinds of shrubs, 12 kinds of Fujimoto, 52 kinds of herbaceous, 4 kinds of bamboo plants, 2 kinds of aquatic plants and five kinds of ferns, etc.The plants were more abundant within the community. Tree layer was rich in plant species,and matched between deciduous and evergreen plants better,and shrub plant species were clearly insufficient and ground cover plants were more abundant.(2)Analyzed the diversity of plant communities of Hang zhou Gushan scenic spot. The results of the analysis were as follows: the canopy density index was overall high In the ridge, hillside area,and canopy density was relatively low at the foothills,and there are many savanna, providing venues for visitors. The marglef index of tree, shrub, grass is1.48; simpson index is 0.671; Shannon-Weiner index is 1.523; Pielou index is 0.721. the plant communities showed high diversity on the whole, the diversity of shrub layer was lower than tree layer and herbaceous layer.(3)The seasonal plants landscape of Santaishan Scenic Area was proved obviously in the chronological order of the changing seasons. The ornamental feature of plants was showed gracefully. There were mainly flower plants in spring,and the main colours were red and yellow;The summer is lack of flower plants,and there are a lot of shade in summer. The foliage plants and ornamental fruit plants were appreciated in autumn, which colours most included red and yellow. The beauty of plants form were enjoyed by many people in winter.(4)Gushan plant landscape space was classified based on the degree of cooperation around the plant,and from the perspective of the art plant configuration, we have studied the classic plant landscape space in Gushan scenic attractions, typical plant landscape space and typical plant landscape space. Meanwhile we analyzed the landscape garden space combination of the plants and buildings, water, roads, rocks, other elements in detail, and summed Gushan plant landscape space construction techniques and features. |
