Plant Investigation And Landscape Evaluation Of Gaofeng Forest Park In Nanning

Forest park botanical landscapes are an integral part of forest park tourism resources,so an accurate and objective assessment of forest park botanical landscapes not only helps to better develop and utilise botanical resources,but also lays a solid foundation for the sustainable development of forest tourism.Gaofeng Forest Park is an important node of Nanning Forest Tourism Circle,and a forest tourism base integrating forest sightseeing,experience,health preservation and popular science education.It is of great significance for the follow-up construction of Gaofeng Forest Park to deeply understand the plant resources,plant community configuration and plant landscape status of Nanning Gaofeng Forest Park.Through the investigation of plant species resources in Gaofeng Forest Park,the sampling survey of typical plant community,the SBE and SD methods are used to evaluate the plant landscape,so as to supplement the research gaps of its plant landscape,provide a theoretical basis for optimizing the plant landscape configuration in the forest park and improving the beauty of the plant landscape,and make contributions to the development of the forest park.The research results obtained are as follows:1.There are a total of 338 species of vascular plants in Gaofeng Forest Park,belonging to 111 families and 270 genera.There are relatively few species of gymnosperms and ferns,with 8 dominant families including Gramineae,Leguminosae,and Euphorbiaceae.The dominant genera include Ficus,Pteridoptera,and Michelia;The lifestyle is complete,with 109 species of trees,79 species of shrubs,134 species of herbs,and vines,with herbaceous plants dominating;There are various ornamental plants,including leaf observation,flower observation,fruit observation,and shape observation.Leaf observation plants are the main type,but colored leaf plants are relatively rare;The park has26 species of rare plants,which have a certain role in science popularization and education.2.The plants with the highest important values in the three layers of trees,shrubs,and grass in the park are fir,hibiscus,and Pilea notata.The overall trend of Patrick index of species richness of plant community is herb layer>shrub layer>tree layer,while Margalef,Simpson and Shannon Wiener indexes are shrub layer>herb layer>tree layer,and the evenness index is shrub layer>tree layer>herb layer.From the average values of richness,diversity,and evenness in each scenic area,the Life Valley area ranks first in both richness and diversity,and second in evenness.The area has rich plant species and levels,with even plant species.3.45 plant community quadrats in Gaofeng Forest Park were evaluated by SBE method and SD method.The average SBE value was 0.0079.The SBE value of the quadrats was graded.The results showed that the number of high-quality landscapes was small,and there was still much room for improvement;Among the 10 landscape factors evaluated by SD,the highest average score is vegetation coverage(2.05),and the lowest is spatial perception(0.99);There are 5 excellent sample plots obtained from the two evaluation results;Combining the correlation analysis and linear regression analysis of the beauty value and SD factor,it is shown that the beauty of the plant landscape in Gaofeng Forest Park is mainly influenced by the sense of plant landscape order,plant landscape color richness,and vegetation coverage.4.The results of the plant community survey and plant landscape evaluation show that Nanning Gao Feng Forest Park has high vegetation cover and excellent plant growth,but there are problems such as the use of few trees in some areas;low orderliness of the plant landscape;poor management of the plant landscape in the mountaineering area;and a slightly monotonous and repetitive plant landscape.It is suggested that in future construction: the number of trees should be reasonably increased to provide shade space;the orderliness of the plant landscape should be improved;the maintenance and management of the plant landscape in the hiking area should be strengthened;and the variety of ornamental plants should be increased to enrich the colours and layers of the plant landscape.
