Study And Reform Of Forest Landscape In The East Scenic Area Of Xingdao Lake In Guangxi

The Xingdao Lake Scenic Area in Guangxi consists of a part of forest land in the state-owned Qinlian Forest Farm.There are 1026 islands of different sizes in the lake,in order to establish the scene of every island have a different landscape.This paper investigates and analyses the Forest Landscape in the East scenic spot of Xingdao Lake by means of literature research,field investigation and AHP analytic hierarchy process.On this basis,the forest facies of the East scenic spot of Xingdao Lake is reformed and studied.The main research results are as follows:1.Study on the Present Situation of Forest Landscape in the East Scenic Spot of Xingdao Lake(1)There are five types of vegetation in the East scenic spot of Xingdao Lake,including coniferous forest,coniferous-broad-leaved mixed forest,evergreen broad-leaved forest,deciduous broad-leaved forest and shrub.Coniferous forest has Masson pine forest,coniferous and broad-leaved mixed forest has:Masson pine+yellow flower wind bollwood forest,Masson pinee+aloes forest,Masson pine+red cone forest,Masson pine+tree forest,Masson pine+firewood forest,Masson pine+sightseeing wood forest,Masson Pine+Gray Lotus Forest,Masson Pine+Golden Peach Forest,Masson Pine+Noble Green stalk Mulberry Forest,Masson Pine+Schisandra Forest in total of 10 plant communities.Evergreen broad-leaved forests include 9 plant communities,such as Alnus sinensis forest,Runnan shavings forest,Gemu forest,Manchurian cone forest,Eucalyptus grandis forest,Acacia crassifolia forest,Eucalyptus grandis + Runnan shavings,Alnus sinensis + Eucalyptus grandis forest,Gemu + Eucalyptus grandis forest,deciduous broad-leaved forests have Maple forest,with shrub in total of 22 community type.Masson pine forest and Eucalyptus forest cover the largest area.(2)Pinus massoniana and Eucalyptus grandis are the dominant species of plant community in the East scenic spot of Xingdao Lake,which have the highest important value in the arbor layer.The shrub layer is dominated by hemp,gum tree,pepper and sandalwood.The herbaceous layer is dominated by ferns,ferns and ferns.The arbor-shrub-grass collocation of the research community is mixed and lacks the sense of landscape hierarchy.(3)A total of 81 species of plants belonging to 72 genera and 49 families were used in the East scenic spot of Xingdao Lake.31 species of trees and 22 species of shrubs were mainly used.Among them,5 species of Color-leafed trees,19 species of flower-viewing and fruit-viewing plants were used,and the species and frequency of plant use were obviously insufficient.The landscape level lacks the change,the color leaf tree species is less,the seasonal phase change is not obvious,the flower view class,the fuit view plant application is less,the garden landscape tree species is lacking,the landscape beauty degree is insufficient,the forest facies is not abundant,need to carry on the further improvement to the scenic spot forest facies.(4)In the East scenic spot of Xingdao Lake,economic tree species are mainly planted.Among them,most of the tree species,such as aloes,shavings Runnan,Gemu,red cone,grey Manglietia and Jinpu peach,have been planted only in recent years.This shows that the forest phase in the scenic spot will change greatly with the growth of these tree species.The age of most Eucalyptus grandis 7 years old,and that of Pinus massoniana has reached the cutting stage.It is conducive to forest facies transformation in scenic spots.2.The forest facies evaluation system of Xingdao Lake East Scenic spot is constructed and the important values of each evaluation factor are compared.In the comparison of criterion layer,ecological quality(0.5697)>landscape level(0.2864)>functional value(0.1439),It is pointed out that to improve the ecological quality of scenic spots should be taken as the primary goal when forest phase transformation is carried out.In the ecological quality level,the highest weight value is the reasonable degree of plant allocation(0.3160),which indicates that the plants selected in the forest transformation of scenic spots must be coordinated with the original trees in the scenic areas and set off against each other.In order to make the plant community more appreciative;In the landscape level,the most important weight is the richness of plant landscape level(0.1247),which shows that the combination of reasonable tree,irrigation and grass plants can make the landscape forest more rich and diverse;In the functional value level,the plant health status(0.0929)is the largest,and the score exceeds the sum of the other two weights,which indicates that the health status of the community plants plays an important role in the functional value of the scenic spot.3.Finally,the forest facies transformation scheme of the East scenic spot of Xingdao Lake is given,and the guiding ideology of giving priority to ecological quality,taking the landscape level next,and finally considering the functional value is put forward according to the forest facies evaluation system of the scenic spot.On the premise of keeping the original tree species in the scenic area as far as possible,the coniferous and broad-leaved mixed forests with complex layers and evergreen and deciduous broad-leaved mixed forests are mainly established.Increasing the color-leaf tree species,native tree species,flowers,fruits,dried plants to create a scenic spot of one island,establishing the scene of landscape changes with the four seasons and every island have a different landscape.
