    Abstract:

    [Objective] The characteristics of plant communities in the natural slope and erosion gully of the subalpine meadow in Lingshan Mountain in Beijing City were investigated and analyzed to provide theoretical basis and technical support for vegetation restoration in erosion gullies.[Methods] The characteristics of plant communities at different sites were studied using the methods of standard ecological investigation methods and statistical analysis.[Results] (1) The Shannon-Wiener index and Margalef index were all as follows:erosion gullynatural slope; (2) The community similarity coefficient and β diversity index between the community of the natural slope and erosion gully were 0.884 and 0.178, respectively, which mean the plant community composition in erosion gullies and natural slopes had higher similarity; (3) The niche breadth and the important value of Poa sphondylodes Trin and Carex dispalata were larger both in the natural slope and erosion gully, which showed that these two species were main dominant species. In addition, most species had niche overlap in both natural slope and erosion gully, but the niche overlap values were relatively small.[Conclusion] Erosion gully is in the early succession and tend to restore the natural state. P. sphondylodes Trin and C. dispalata are the pioneer dominant species of community.
