Study On Community Structure And Landscape Degree Of Scenic Forest In Yunding Mountain Scenic Area Of Jintang

Scenic beauty is to have higher aesthetic value and to satisfy people aesthetic demand is the management objectives of forest,is a kind of special purpose of ecological public welfare forest,as the body of the scenic area landscape resources,scenic forest in the use of its functions of landscape and the protection of scenic spot ecological environment plays an important role.At present,the requirement of landscape forest construction in China has changed from only paying attention to the function of landscape to the development of ecology and landscape.For development and are developing some new features of forest resources of the construction of the landscape resources of scenic spots,forest park,etc.,and positive action,and in finding out about money at the same time,by using scientific means of scenic resources analysis and evaluation of scenic forest scenic spot its structure and the degree of beauty,for the scientific and reasonable development and management foundation and reference for the scenic spot.Based on this,this article from the internal community structure and formation of the landscape effect of scenic forests,forest managers,community ecology,forest ecology theory,such as set up 20 in genting hill scenic area scenic forest sample plots,degree of community structure of scenic beauty,beauty and the relationship between the two has carried on the quantification analysis,put forward some quantitative index of construction.The main conclusions are as follows:（1）in this study,landscape forest was divided into four landscape types according to its substrate:needle-width mixed forest,deciduous broad-leaved forest,evergreen deciduous broad-leaved forest and coniferous forest.In terms of species diversity,attention should be paid to restoring species diversity in landscape forest ecological restoration.In terms of horizontal structure,the density of coniferous forest is too high,which needs to be dredged.Except 17 of the sample land,the landscape forest has good canopy density.In terms of vertical structure,the landscape forest in the scenic area is composed of the multi-layer model of"Joe+irrigation+grass".In terms of forest phase effect and seasonal phase change,the majority of evergreen tree species are in the landscape forest.In spring,summer and autumn,there are many species of ornamental flowers and leaf trees.Generally speaking,yunding mountain scenic area landscape forest can be achieved throughout the year.（2）the SBE method was used to evaluate the landscape effect of landscape forest and forest,and the standard value of landscape SBE was obtained.On the basis of summarizing the predecessors’research,combines the actual conditions of the survey,determined the 16primary landscape factors,three qualitative factors and quantitative factors,13 and Pearson correlation coefficient test,excluding predictor of correlation coefficient is not high and the SBE standard regression model,select three with the most relevant factor score values:Shannon-Wiener index（X₈）,herbaceous plant(X₁₁),color diversity(X₁₅),get the beauty degree evaluation model for:By S_SBE=43.883X₈+0.059 X₁₁+16.298X₁₅-130.008.Will be 20 scenic sample SBE score values and the four classes of scenic SBE score values are compared,and combining can be concluded that mixed needle leaf and one of the most popular with visitors,coniferous forest the least popular with tourists,deciduous broad-leaved forest and evergreen and deciduous broad-leaved forest values close to.The coniferous and broad-brush mixed forest has a good vertical stratification structure,which conforms to the public’s aesthetics and gets the highest score of scenic beauty.（3）analysis of scenic beauty and community structural factor relations,in the public appreciation of scenic forest towards herbs rich,the community and with high complexity of colorful scenic beauty.Beauty degree evaluation model as well as landscape effect of scenic forests and set up clear quantification relationship between community structure,to genting hill scenic spot in scenic landscape improvement and ecological optimization planning and provide a scientific basis.
