摘  要：
在流动、半固定、固定沙地上选取典型样地,对毛乌素沙地油蒿群落的种类组成及其生态类型结构进行调查。结果表明,油蒿群落分为灌木层和草本层。灌木层以油蒿为主,伴有花棒、羊柴等,油蒿高度在0.51～0.62 m,并且呈明显的集群分布;草本层种类稀少,共有11种,隶属9科10属,以菊科、禾本科为主;样地有3个植被分布区型,其中蒙古—华北区型种类最多(45.5%),其次为蒙古—东北—兴安—华北区型(36.4%),蒙古—东北—华北分布区型种类最少(18.2%);3个水分生态类型中,旱生植物最多(54.5%),中旱生的和中生的分别占36.4%和9.1%;在4个生活型中,地面芽植物最多,占36.4%。

摘  要：
Typical sample plots were chose in flow,semi-fixed and fixed sand and the species composition and the ecology type structure of Artemisia ordosica community were investigated.The results showed that the Artemisia ordosica community could be divided into 2 layers,namely tree shrub and herb.Shrub layer was mainly composed of Artemisia ordosica,about 0.51 m to 0.62 m high,which follow obvious clumped distribution,accompanying with Hedysarum scoparium and Hedysarum fruticosum,etc;The herb layer had only 11 species,which subordinated 10 branches and 9 categories.Herb layer was composed of composite and gramineae primarily;There are 3 vegetation distribution areas in sample plots,Mongolian-North China distribution area was the most(45.4%),followed by Mongolian-Northeast-Dahuricia-North China distribution area(36.4%),and Mongolian-Northeast-North China distribution area was the least(18.2%).Among three water ecological types xerophytes occupied most(54.5%),and mesoxerophytes and mesophytes occupied 36.4% and 9.1%.In 4 kinds of life,forms hemicryptophyte was the most,accounting for 36.4%.
