摘要:
根据乌兰布和沙漠东北部绿洲东缘7个样区25个样地的样方调查数据，对该区植物群落结构及物种多样性进行分析。结果表明：研究区自然植被共有52种，分属17科45属，以菊科为优势种，禾本科、豆科和藜科为亚优势种，其他13科为伴生种；群落结构类型以灌木群落为主，草本群落次之；根据群落物种多样性变化规律，可以将研究区划分为南北两部分，南部多样性指数变化幅度较小且保持较高水平，北部多样性指数变化幅度较大且相对较低；沙漠地区通过绿洲防护林建设，能有效改善绿洲外围植物生长环境，增加植物群落物种多样性，控制沙漠扩张。
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.
