摘　　要：1998至 2 0 0 0年 ,作者对准噶尔盆地东部波斑鸨繁殖栖息地作了考察研究。结果表明 ,由木本猪毛菜 (Salsolaarbuscula )和驼绒藜 (Ceratoideslatens)组成的条块状灌丛随机地散布在视野开阔的假木贼 (Anabasissalsa ) -蒿 (Artemisiasp .)群落中为栖息地景观。研究发现 ,绝大多数波斑鸨的巢址和炫耀点都位于植被高度、盖度、密度较低 ,视野开阔的假木贼 -蒿群落中 ,同时又总是靠近条块状灌丛。这种镶嵌的植物群落所构成的栖息地为波斑鸨的生存、繁衍提供了理想场所。Breeding habitat selected by Houbara bustard in eastern Jungar Basin were studied from 1998 to 2000. Various associations of short sub-shrubs (Anabasis sp. and Artemisia sp.) dominated the vegetation in the core area. Some densely bushy patches consist of Salsola arbuscula and Ceratoides latens intersperse randomly in the Anabasis sp. communities. Vegetation in nesting sites and display sites is short with relatively low cover, and low density. However, most of the nesting sites and display sites are close to bushy patches. Such various vegetation structures provide an ideal place for houbara surviving and breeding.
