The Plants Landscape Research Of National Forest Park Of Hangzhou Banshan

As the utilization of urban green space gradually becomes saturated,the construction of the park gradually expands to the urban forest.Forest tourism has become a hot spot in the context of the country's advocacy of building park cities and building 10,000 forest parks.The forest plant landscape is more natural and ecological than the traditional urban green space landscape,and has a therapeutic effect,which is widely praised.Hangzhou Banshan National Forest Park covers an area of 1002.88 hectares,with a forest area of 931.81 hectares and a forest coverage rate of 92.9%.It is one of the most important forests for the preservation of urbanization in the urbanization area of Hangzhou.This study examines its plants in detail.Starting from the landscape,analyzing its characteristics and refining the pattern of forest plant landscape construction.The main findings are as follows:(1)The existing vegetation base of the park can be divided into 8 categories,evergreen broad-leaved forest(57.7%),evergreen deciduous broad-leaved mixed forest(19.9%),deciduous broad-leaved forest(16.6%),evergreen coniferous forest(0.7%),bamboo forest(1.91%),economic forest(0.94%),shrub forest(0.001%),grassland(0.001%).After long-term natural succession and artificial disturbance,the proportion of evergreen broad-leaved forest and evergreen deciduous broad-leaved mixed forest increased by 85% compared with 30 years ago,and the evergreen and deciduous mixed forest gradually evolved into evergreen broad-leaved forest.The proportion of other types decreased drastically.It can be predicted that after 50 years,the probability of vegetation is mainly in evergreen broad-leaved forest(90%),and the distribution of evergreen deciduous broad-leaved forest is small(9.5%).The proportion of other types(0%)-0.5%);100 years later,the proportion of evergreen broad-leaved forests(99%),other species are rarely distributed(0%-1%).The above predictions are contrary to the needs of natural ecology and landscape diversity,and are not conducive to the protection of biodiversity.(2)According to the survey,a total of 266 species of plants belong to 89 families and 178 genera,of which 68% are native plants,20% higher than the application types of native plants in urban parks.Plant resources also have great development space,creating outstanding Forest landscape with zonal and regional characteristics of plant landscapes.The mountain vegetation in Hangzhou Banshan National Park is mainly protected and moderately developed.The existing resources can be used to increase the ornamental value of the plant in the tour system,and the high-quality forest plant landscape is displayed.The far-line area is mainly for conservation,and the mountain closure is used to reduce the tourist activities.The plant landscape in the scenic spot serves the tourists' viewing and recreation functions,paying attention to the construction of forest plant landscapes,making the park plant landscape different from the general urban park plant landscape and forming regional(3)At present,the landscape forest is in a period of rapid growth,and the landscape effect is in a dynamic change.Some important landscape communities(such as the masson pine forest)have a single structure,fragile and unstable structure,and are susceptible to pests and diseases or extreme weather.The community,closed hills and afforestation is completely unstable with natural succession.It is suggested to add artificial disturbance(30%),directional tending,promote the succession process of degraded forests,assist in stabilizing the community renewal layer,and realize the natural renewal of the community to the target community to form a stable landscape forest.characteristics.(4)According to the type of activity space,the scenic spots are divided into three kinds of static surface space: enclosed space(50%),semi-open space(40%),open space(10%),and a dynamic line Space: the space of the tour.Plants are on average 20% higher than the same type of urban park activity space plants,with a more natural form and a 25% higher branch point.(5)The proportion of scenic-shaped plants is 20%,which is 30% less than urban green space.Among them,90% of the existing ones are poorly managed and the landscape effect is not good.Therefore,low-maintenance and near-natural construction modes are advocated,highlighting that urban forests are different from urban parks.Natural beauty,in line with the succession and growth of the forest itself,also meets the requirements of the forest beauty landscape.
