摘 要:1999~ 2 0 0 1年 6~ 7月 ,利用粪便示踪和野外直接观察法对准噶尔盆地东部波斑鸨 (Chlamydotisundula tamacqueenii)夏季栖息地进行了采样研究。结果表明 :波斑鸨夏季栖息地地势平坦 ,视野开阔 ,沙质土和粘土上旱生和盐生荒漠植被广泛分布 ,植被稀疏、低矮 ,并镶嵌有相对较高的灌丛块 ;影响波斑鸨夏季栖息地选择的环境因子是植物种数、植被密度和植被盖度 ;栖息地内的植被盖度、植被密度、草本植物种数、角果藜密度和距邻近灌丛块距离都显著低于对照地内的相应成分。Summer habitat selection by Houbara bustard in eastern Jungar Basin, Xinjiang were studied from June to July 1999-2001. It was found that the houbara's preferred sites were the places, flat and dominated by associations of short and open xero-lalophytic plants and interspersed randomly by densely bushy patches. In summer, houbara selected habitats with relatively low vegetative cover, vegetative density, herb species richness, density of Ceratocarpus sp. The average distance to the closest shrub patch was significantly shorter at utilization-sites than at random sites. Plant species richness, vegetative density and vegetative cover were the most important factors that determined the summer habitat selection of houbara bustard.
