| 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0．51～0．62m，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，其中蒙古一华北区型种类最多（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％。

| Abstract: | 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 spec... |
