Plant Community Structure and Species Diversity Characteristics in Traditional Villages of Dong Nationality in Southeastern Guizhou and Their Interrelation

Abstract

Abstract To investigate the plant community structure and species diversity characteristics in the traditional villages of Dong nationality in Southeastern Guizhou and the interrelation between the two, the author adopts biodiversity theory, fractal theory, and forest stand spatial structure parameters to analyze the plant community structure and species diversity characteristics in the traditional villages of Dong nationality in Southeastern Guizhou. The coupling relationship between the two is also investigated. Results showed that: the plant communities in the traditional villages of Dong nationality display a low-degree clustering pattern, and the communities are in a transition from moderately mingled to stable states. Community structure parameters and species diversity are significantly different among different types of green spaces and three spaces, but show no significant changes under different topography and landforms. The spatial isolation degree of tree species in the arbor layer, the individual spatial distribution pattern and the spatial occupancy degree of the arbor layer are the main factors affecting species diversity in the arbor and shrub layer, while the main factor that affects the herb layer diversity is the competitiveness of the arbor layer. Dong culture acts as a key factor in maintaining the plant community structure and species diversity in the traditional villages of Dong nationality in Southeastern Guizhou. In the future, we need coordinate the relationship between ethnic cultural development and ecological environmental protection, strengthen ethnic culture construction to promote the sustainable development of biodiversity. This study can provide a theoretical foundation for the construction of plant landscapes under the background of rural revitalization, which is of important significance to the construction of an ecologically livable environment.
