Research On Plant Landscape Of Zhongnan Baicao Yuan Scenic Spot In Anji,Zhejiang

Zhongnan Baicao Yuan scenic spotis located in Anji,the birthplace of the "two-mountain theory" which is an important place for eco-tourism in Anji.Vegetation coverage rate is up to 95%and plant landscape is an important part of the scenic area.In this paper,the plant landscape of Zhongnan Baicao Yuan scenic spot is taken as the object,and the method of combining route survey and sample survey is adopted.The plant landscape is studied from three levels of plant species,community and landscape.AHP analytic hierarchy process(AHP)and fuzzy comprehensive evaluation method are used to evaluate plant landscape.The research results are as follows:There are 211 species of Vascular Plant belonging to 175 genera and 88 families in the scenic spot of the hundred grassland in Zhongnan Baicao Yuan scenic spot.Plant species are dispersed in the composition of families and genera.Among them,Gramineae and Rosaceae are the most species,and the ratio of evergreen tree species to deciduous tree species is 1:1.4.The plant community structure is relatively simple,and the community species diversity is manifested as the shrub layer > herb layer >tree layer.The vegetation types are abundant,mainly including bamboo forest(31.08%),coniferous forest(17.79%),mixed bamboo forest and wood forest(12.72%),mixed coniferous forest(11.24%).Bamboo forest,coniferous forest and mixed coniferous forest accounted for 68.83% of the total area.The main type of the scenic area is evergreen vegetation,the seasonal changes of the landscape are not distinct,and the timing of the landscape is deficient.Twelve comprehensive evaluation indexes are selected from the three levels of ornamental,ecological and service to construct the plant landscape evaluation system of the hundred grassland scenic spots in Zhongnan Baicao Yuan.From the plant landscape comprehensive evaluation results of16 sample plots in the scenic spot,plant landscape in tier Ⅱ have 3(Respectively sample plot 3,sample plot 10,sample plot 11),18.75%,Ⅲ magnitude 7,43.75%,Ⅳ magnitude 6,37.5%.The plant landscape in the scenic area is at a medium level,with a great room for improvement.According to the results of comprehensive evaluation of plant landscape and field research,the plant landscape optimization system at three levels of "landscape--community--species" is constructed.In the process of plant landscape optimization,the existing plant resources should be fully utilized to increase the vegetation types such as deciduous broadleaf forest and evergreen deciduous broadleaf mixed forest which can enrich the vegetation types of the scenic spot,increase the plant landscape color system,create a rich seasonal landscape.According to the principle of suitable sites and trees,52 species of excellent landscape plants are recommended.
