Analysis on Urban Forest Landscape Patterns Based on ArcGIS and Fragstats——Take Liuzhou Lianhua Mountain as Example
Liuzhou Lianhua Mountain serves as large ecological functional area in Liuzhou,which is planed to be developed into national urban forest park,so it is necessary to investigate and organize landscape resources and characteristics of landscape patterns.Taking forest phase vector maps of Lianhua Mountain in 2020 as da-ta source,using ArcGIS and Fragstats softwares,11 landscape indexes were selected to analyze general charac-teristics,patch characteristics and heterogeneity of landscapes.Results showed that forest communities in Lian-hua Mountain were overall stable with good ecological functions,dominated by landscapes of Pinus massoniana mixed forests,natural forests(miscellaneous shrub forests)and eucalypt forests.Mixed and natural forests(mis-cellaneous shrub forests)were less affected by human activities.Pine and broad-leaved mixed forests were more developed in landscape.Water sources should be developed urgently.Forest landscape had high heteroge-neity with more patches and less patch areas.It was recommended to enhance richness of plant communities,ar-range transformation of commercial forests scientifically and rationally,leverage ecological advantages of forest landscapes and reform urban landscapes.Results could provide scientific basis and theoretical support for land-scape transformation,land use optimization and ecological safety pattern construction in Lianhua Mountain.
