Analysis of Plant Species Diversity Characteristics and Spatial Differences After Forest Fire Damage
To explore the restoration of artificial vegetation and the characteristics of biodiversity under different site conditions after fire damage in the Panxi region,this study takes the Lushan area of Xichang City as the research subject.Using relevant theories and methods of biodiversity,this paper analyzes the characteristics of plant species diversity and their influencing factors after the post-fire vegetation restoration in Lushan.The results show that:①The four species diversity indices of plant communities in the Lushan area are all relatively low,with significant differences in diversity indices among different regions;②There are differences in species diversity among different slope positions,with obvious differences in plant species diversity between the middle slope and the upper and lower slopes,while there are no significant differences between the upper and lower slopes;③ There are significant differences in species diversity indices of plant communities among different directions within the study area,with the east and north directions having higher plant diversity indices than other areas,while the west and south regions have lower indices.Plant community species diversity in the study area varies greatly due to different topography and geomorphology as well as varying degrees of damage.Appropriate measures should be taken according to different site conditions to restore the regional ecosystem,strengthen connections between habitats within the area,and facilitate the recovery and protection of the ecology within the study area.
