摘要: 油蒿为鄂尔多斯高原植被的优势种和建群种,油蒿群落的植物多样性有向顶极阶段增加的趋势。植物多样性的季节变化与气候的季节变化密切相关。人类活动特别是过度放牧,引起油蒿群落的退化,导致植物多样性降低。围育可使退化的油蒿群落向正向演替进行,使群落的植物多样性提高。

关键词: 鄂尔多斯高原, 油蒿群落, 植物多样性

Abstract: Artemisia ordosica is the dominant species or edificator of Ordos Plateau vegetation.Artemisia ordosica community plant diversity has been tending to increase towards its climax.The seasonal dynamics of the plant diversity is closely related to that of climate.Human activities,especially overgrazing,result in deterioration of the community with decline of the plant diversity.Enclosure and breeding can enhance the plant diversity of Artemisia ordosica community which has been degraded.

Key words: Ordos plateau, Artemisia ordosica community, Plant diversity
