Landscape Evaluation And Planning Practice Of Ecological Landscape Forest

This article closely follows the theme of ecological landscape forest landscape evaluation and planning,combs and analyzes the existing design theory and two related cases,and takes the Tiantai Mountain Tongbai Scenic Area as a practical case to take an on-site investigation and data analysis of the existing forest land landscape And landscape evaluation,and carry out ecological landscape forest landscape improvement planning accordingly.The main conclusions of the paper are as follows:1.Landscape evaluation and planning methods of landscape forestThrough a large number of studies,the methods used in landscape forest landscape evaluation mainly include descriptive factor method,questionnaire survey method and psychophysical method,among which psychophysical methods are widely used.Through case analysis,it was found that there are problems such as unreasonable proportions of coniferous forest,broad-leaved forest,and coniferous-broadleaf mixed forest in the planning of ecological landscape forest,single tree species and insignificant seasonal changes,etc.,which should attract the attention of the designer;Or the method of replanting has achieved good results in enhancing the seasonal changes of plants and enriching the structure of plant communities,which is worthy of reference.2.Landscape evaluation of landscape forest in Tongbai Scenic Spot(1)The scenic forest in the Tongbai Palace Scenic Area of Tiantai Mountain can be divided into two types: subtropical evergreen deciduous broad-leaved mixed forest and coniferous broad-leaved mixed forest,with a total of 58 plants,85 genera and 105 species..In the 10 typical plots surveyed,80% of the plant community is a reasonable forest layer structure,and the plant community structure is stable.The landscape level of 20% of plant communities is not obvious,and most of them are bamboo forests without shrub layers.The plant community is mainly a three-layer structure model of "Arbor + shrub + grass".The plant community has good stability and a clear sense of hierarchy.The zonality of vegetation in scenic forest plots is not prominent,the diversity of landscape types is not obvious,and the proportions of coniferous forest,broad-leaved forest,and coniferous-broad mixed forest are unreasonable.The overall seasonal change is not obvious.The plots with four seasons account for 30% of the total plots,the plots with three seasons account for 30% of the plots,and the plots with two seasonsaccount for 40% of the plots.It shows that the proportion of plant color leaf trees in the Tongbai Scenic Area of Tiantai Mountain is less,and that of evergreen trees is more.(2)Through the partial correlation analysis in the model,it is concluded that the larger landscape factors that affect the scenic forest of the Tongbai Palace scenic spot in Tiantai Mountain are color richness(X1),layering(X2)and naturalness(X3),and an evaluation model Y =-1.524 + 1.114X1-0.727X2 + 0.368X3.The results of this model show that most people love.3.Practice of scenic forest planning in Tongbai Scenic SpotAccording to the zonal vegetation in the landscape forest,the plant community structure is adjusted through scientific planting methods to create an ecological landscape forest similar to the natural plant community structure,with high stability,obvious regional characteristics,and rich cultural connotations.By replanting background forests,increasing foreground forests and forest margins,removing poorly grown trees,and further enhancing plant layering;adding evergreen and broad-leaved tree species,reducing the density of coniferous forests,reconciling the proportion of coniferous and broad-leaved forests;through thinning High-density masson pine forest and the treatment of branches and stumps,thin shrubs with poor growth,diseased trees,replantation of local precious colored forest tree species,adjustment of the proportion of spring flowers and autumn foliage ornamental tree species,and improvement of the seasonal change of forest belt landscape.In addition,by adding wet plants,and combining water-resistant wet trees and shrubs,different spatial structures are created to further enrich the footpaths and waterfront plant landscape.
