Research On Aesthetic Quality Evaluation And Improvement Technique Of Peri-urban Recreational Forest In Mountain Valley

Peri-urban forest is an important component of urban ecosystem,with the development of society, the diversity functions of forest to satisfy the needs of local residents. Such as creating fitness trails in the forest to meet the demands of leisure,entertainment,sightseeing.Because of the poor quality of landscape and plant cummunity,cannot meet the need of ornamental.Taking the recreational forest surrounding the city in the middle of Zhejiang which developed on the basis of ecological non-commercial forest as the research object.Aopting the senic beauty estimation method to evaluated the in-forest land scape aesthetic quality and find the main factors.With the help of virtual reality te-chnology,integrated application of various simulation softwares.Stand density index. Carrying out the single factor control experiment.At last summarize and emprove t he optimization technology,and application tests,the main results were as followed:(1) the five types.evergreen broad-leaved forest,Deciduous broad leaved forest, Evergreen,deciduous broad-leaved mixed forest,Coniferous forest,mixed broadleaf-co nifer forest have no significant differencce degree of SBE.So that,the tree species composition have little effect on the scenery.The main factors were tree form,com-munity structure and space perception.(2) In order to avoid sample scenarios and photographs boundaries inconsisten-t phenomenon.This study sdopt triangle sanmple set and satisfy the requirement o f research and find out the triangle area.The depth was 25m,corresponding to an area of 563m2.(3) Adopting activity exhibition in order to judge conveniently.There was no s ignificant difference between photo and field evaluation.Imade evaluation of no si-dnificant difference compared with the corresponding video evaluation testresult.Ph-otos of high quality vedio together can get better landscape effect;Photo of poor quality of vedio together get low effective video landscape effect.(4) Due to Speedtree,AutoCAD,Lumion softwares,implement trees monomer pa-rameterized modeling.Trees in the range of random distribution of the scene and f orest scene synthesis.Finally realized the realistic and measurable forest scene.Buil ding targets prove that under the background of current technology.The integrated...
