Study On The Typical Landscape Evaluation Of Xishan National Forest Park Based On Vision And Audition

In order to improve the quality of visual and auditory sensory experience in Xishan National Forest Park,this paper systematically evaluates different types of visual and auditory landscapes,explores the differences of sensory experience caused by different visual and auditory landscapes and their combinations,and on this basis,summarizes the existing problems of visual and auditory landscapes,and puts forward the optimization scheme of visual and auditory landscapes in Xishan National Forest Park.Based on the basic theoretical research and field investigation of Xishan National Forest Park,62 typical plant communities were selected to investigate and analyze the species composition,community structure characteristics,plant community configuration,plant community landscape effect,etc.Based on relevant theoretical research,Select the visual and auditory evaluation indicators,and use the factor analysis method to establish an evaluation model to evaluate and analyze the typical visual landscape,auditory landscape,and audiovisual comprehensive landscape of Xishan National Forest Park.Finally,based on the evaluation results and current situation survey,to provide implementation plan for the improvement of vision and hearing landscape in Xishan National Forest Park..The research results are mainly in the following aspects:（1）Investigation and research on the status of plant communities in Xishan National Forest Park.From the perspective of species composition,there are78 species of plants in 62plant communities in forest park,belonging to 31 families and 61 genera.They are mainly composed of Rosaceae,Poaceae,Leguminosae,Pinaceae,etc.The plant composition of the family;the dominant treespecies are mainly native tree species,mainly including:Scutellaria baicalensis,Pinus tabulaeformis,Platycladus orientalis,Hickory peach,Yuanbaofeng,Luan tree,Robinia pseudoacacia,Elm tree,Quercus variabilis,etc.From the perspective of plant community structure,This plant（arbor+shrub）occupies the main advantage,with a total of 63species,which is the main body of the plantcommunity landscape in the forest park;the proportion of evergreen and deciduoustree species is unevenly distributed,mainly deciduous trees and deciduousshrubs From the perspective of plant community configuration The horizontal structureof the forest park is dominated by mixed communities.Among them,coniferousforests are dominated by Pinus tabulaeformis and lateral Berlin,and deciduous broad-leaved forests are mainly Robinia pseudoacacia forest,Luan forest,mountain peach forest,Quercus variabilis forest,Yuanbao maple forest,etc;The vertical structure is dominated by the Joe-Irrigation-Grass multi-layer model.From the perspective of the plant community landscape effect,the ornamental characteristic trees are mainly flower-viewing plants,and the leaf-viewing plants are also rich,but there are fewer fruit-viewing and shape-viewing tree species.Some species have two ornamental characteristics,and in ornamental characteristics,the type of tree species ornamental characteristics are more diverse,less herbaceous plants ornamental species.（2）Research on the visual landscape evaluation of Xishan National Forest Park.Select evaluation indicators and research to obtain data,and use factor analysis to evaluate visual landscape,meanwhile,establish the visual landscape evaluation model of Xishan National Forest Park:F=0.42268F₁+0.1801F₂+0.23972F₃+0.15076F₄.According to the evaluation results,the discriminant analysis and cluster analysis are used to classify the visual landscape plots.Of the 62 plant landscape communities in the forest parks surveyed,19 are first-level landscapes.It accounts for 30.6%of the total sample plot;15 secondary landscapes,accounting for 24.3%of the total sample plot;11 tertiary landscapes,accounting for 17.7%of the total sample plot,and 17 fourth-level landscapes,accounting for the total sample plot 27.4%.（3）Research on the evaluation of auditory landscape in Xishan National Forest Park.Using SD method to obtain evaluation data,evaluate the auditory landscape by factor analysis method,and establish an auditory landscape evaluation model:F=0.42268F₁+0.1801F₂+0.23972F₃+0.15076F₄.According to the analysis of the evaluation results,the sound landscape of Forest Park is not rich and attractive.There are many and wide distribution of people flow activity sites in the near mountain area,and it is easy to be interfered by the external environment.The main part is artificial sound,especially near the edge of Forest Park,which is easily interfered by the external communication sound and mechanical sound.The naturalness,sweetness,fluency and coordination of the sound are relatively high Low,the effect of hearing experience is poor;Forest Park remote mountain area,high-altitude area,terrain undulating area,mainly static recreation space,little external interference,high degree of naturalness,frequent bird activities,good hearing experience effect.（4）Comprehensive evaluation of visual and auditory landscape in Xishan National Forest Park.Based on visual and auditory evaluation data,a comprehensive evaluation model of the visual and the auditory landscape:F=0.48202F₁+0.17021F₂+0.14518F₃+0.11311F₄+0.08948F_5.According to the evaluation results,the top samples of audiovisual sensory quality are Robinia pseudoacacia forest,Happy Forest,Hongyeling,Banshanting and other plots.The plots include Dongmen Entrance Waterfall,Diaolou,antique buildings and other plots.Compared with the separate evaluation of visual and auditory landscapes,the comprehensive audiovisual evaluation results have significant changes.Visual and auditory have a certain correlation,under different environmental conditions,the relationship between vision and hearing will also be different,but this relationship has a certain relationship Restrictions:The relationship between the two is not 1+1 greater than 2,and it needs to be analyzed according to the specific environmental conditions.（5）Study on the visual and auditory landscape optimization scheme of Xishan National Forest Park.According to the results of visual and auditory landscape evaluation and field investigation and analysis,this paper summarizes the main problems of visual and auditory experience in Xishan National Forest Park,draws on the achievements and cases of previous studies,and puts forward the visual landscape optimization strategies from the perspective of functional zoning Construction:increase the ornamental specific tree species,optimize the original plant community structure,pay attention to the over allocation between tree,shrub and grass layers and under forest Space construction and other contents;and the transformation and improvement of the typical plant communities in each functional area;in terms of the improvement of the auditory landscape,mainly for the existing problems and the construction objectives of each functional area to optimize,increase the recreational forest land to attract birds,set up interesting auditory experience facilities,use the forest sound landscape to create environmental and cultural atmosphere,and plant sound insulation near the edge of the Forest Park Optimize and improve the plants with good effect.
