摘 要 ：本文利用数量方法对毛乌素沙地景观生态类型进行了自上而下的等级式划分，共划分出１０种景观生态类型，并总结了各种景观生态类型的主要性质，对其景观管理措施进行了讨论。还对所划分出的景观生态类型的灌丛的生物多样性进行了分析，其物种丰富度低，而优势度较高，均匀度较低。提出毛乌素沙地草地管理的景观和生物多样性原则。

Abstract:hierarchical numerical method based on the two methods of TWINSPAN (Two WayIndicator Species Analysis)and DCA (Detrended Correspondence Analysis)from the CornellEcology Program(CEP)and involving 17 variables from peddogical ones to hydrological,vegetational,geological and geomorphological ones was used to classify the Maowusu sand-lands into the following 10 landscape ecotypes:salinized lowland,wet lowland,sandcoveredlowland,lowland with a thick sandcover,Nitraria lowland,xili,soft ridge,sandcovered ridge,f...
