Analysis of plant population and distribution characteristics of coniferous forest in Mangdang Mountain Nature Reserve
In order to investigate the wild plant population and distribution law in Mangdang Mountain Nature Reserve,a supplementary survey of coniferous forest plant population in 2021-2022 was conducted on the basis of background survey,and the substrata,plant number,maximum/average diameter at breast height,abundance,frequency,density,evenness and significance of each species in the community were investigated.The results showed that the coniferous forest plant population was mainly composed of plant communities formed by Chinese fir,masson pine and Huangshan pine,with 65,58 and 36 plant species,respectively.The distribution of plant population in coniferous forest was different,and the distribution of plant population in masson pine forest community was more uniform.The significance of dominant species in the community showed that with the increase of altitude,the importance value of dominant species in the community increased significantly,and the population distribution level was obvious.In summary,the distribution of coniferous forest plant populations in the area had distinct levels and obvious changes.The plant communities in Chinese fir forest and masson pine forest were rich in species,while the plant species in Huangshan pine forest were relatively single,and the natural vegetation ecosystem is well preserved.This study provides a reference for the exploitation and utilization of wild plant resources in Mangdang Mountain Nature Reserve.
