Evaluation Of The Beauty Of The Limestone Mountain Vegetation After Short-term Recovery

This paper sets aesthetic forests of limestone mountain and vegetation under different plant disposition patterns after five-years' recovery in Lvliang mountain scenic areas of Xuzhou City as the object of study to explore the beauty quality of limestone mountain and vegetation after five-years' recovery, applying the method of SBE to evaluate scenic beauty values and aesthetic value of aesthetic forests in different seasons of landscape types of different plant disposition patterns around mountain tour footpath, vehicle arterial road, riverside bank and human landscapes; This paper also analyzes the effect of landscape elements like species composition, stand density, color changes on beauty quality, establishing the multiple regression model between influencing factors and scenic beauty values, making optimal prediction of plant disposition patterns to provide guidance for construction of ecological landscape forests in suburban areas of cities. Main results are as follows.1.In the aesthetic forest of mountain tour footpath and vehicle arterial road, plant disposition patterns of evergreen single tree species like artificial platycladus orientalis forests and ligustrum lucidum pure forests achieved the highest scenic beauty values; Plant disposition patterns of willow + Sapium sebiferum + photinia serrulata + Forsythia viridissima Lindl achieved the highest scenic beauty values in riverside bank; Plant disposition patterns of cinnamomum camphora Presl + Ligustrum lucidum + purple-leaf plum+ photinia serrulata + Pittosporum tobira+ Ligustrum japonicum 'Howardii' achieved the highest scenic beauty values around human landscapes.2.The main factors that affect beauty quality of aesthetic forests on both sides of mountain tour footpath are the average diameter at breast height, vision under forests, stem form and the life style structure; Influential factors on both sides of vehicle arterial road are the average diameter at breast height, tree species composition, canopy lines, life style structure and tree shape; Influential factors in riverside bank are stem form, color changes and planting patterns; Planting patterns, other non-plant factors and plant levels are the main factors that influence the vegetation landscape quality of human landscape.3.According to the model, it is suggested that we should plant trees of average diameter at breast height of 10 cm to 15 cm with straight trunk, taking simple life structure and the planting mode of open space under forests; On both sides of arterial road, you should plant tree species of tower type, taking the collocation planting methods of a variety of plants, creating crown line of beautiful forests; we should freestyle planting patterns in riverside bank, selecting tree species with abundant colors or regular planting tree species with straight trunk to match willows; You should take garden planting around human landscape with mutual collocation of a variety of grass and shrubs to build the landscape with comparably obvious level.
