- Abstract:
- According to quadrat survey data belonging to 25 sample plots of 7 sample areas in the oasis of northeastern margin of Ulanbuh desert, we analysed the community structure and species diversity of plant. The results show that there are 52 species of natural plants in the study area, which belong to 17 families and 45 genera, compositae is the dominant species, gramineae, leguminosae and chenopodiaceae are the sub dominant species, other 13 families are companion species; Most of community structure types are shrub communities, the second is herbaceous communities; According to the changes of species diversity, the research area can be divided into two parts: north and south, the range of diversity index change is small and the index maintains a high level in southern area, in northern area, the range of diversity index change is relatively larger and the index maintains a low level; Construction of oasis shelter forest can effectively improve plant growth environment around oasis, increase the species diversity of the plant community, control the expansion of desert.
