摘要:
 运用重要值、生态位宽度和生态位重叠度，对石羊河下游裸果木群落生态位特征进行研究，分析石羊河下游裸果木群落对资源的利用状况，揭示裸果木群落的结构和稳定性，以期明确裸果木群落各物种对环境的生态适应性及种间关系，为裸果木群落的保护、恢复和合理利用提供科学依据。结果表明：1) 裸果木群落30个物种隶属13科28属。在裸果木群落中，裸果木的重要值和生态位宽度都明显高于群落中其他物种，为群落优势种，但裸果木群落极不稳定。2) 在整个群落中生态位宽度从大到小依次是：裸果木、灌木亚菊、沙生针茅、猫头刺、泡泡刺、刺旋花、刺沙蓬、红砂等，在植物群落构建中起着重要的作用。3) 生态位宽度大的物种与裸果木生态位重叠度成正比，生态位宽度和与裸果木生态位重叠度较大的物种有沙生针茅、灌木亚菊、猫头刺、泡泡刺、刺旋花等。4) 裸果木群落中其它物种之间的生态位重叠程度总体偏低，只有个别的物种之间生态位重叠较大。
Abstract:
 The niche characteristics of Gymnocarpos przewalskii community (GPC) in the lower reaches of Shiyang river were studied by calculating the index of importance value,niche width and niche overlap degree.The resources utilization of GPC was examined to reveal the structure and stability of the community,to clarify the ecological adaptability and interspecific relationships of the species in GPC to the environment,and to provide scientific bases for the protection,restoration and rational utilization of GPC.It was found that 1) there existed 30 species belonging to 28 genera 13 families in the community,in which G.przewalskii was the dominant species The importance value and niche breadth of the G.przewalskii were significantly higher than those of other species in GPC.However,the GPC was extremely unstable.2) In the whole community,the niche breadth was in the order (from large to small) of G.przewalskii,Ajania fruticulosa,Stipa plareosa,Oxytropis aciphylla,Nitraria sphaerocarpa,Convolvulus tragacanthoides,Salsola ruthenica and Reaumuria soongorica,which indicated the critical role of these species in the structure of the community.3) Plant species with a large niche width,such as S.plareosa,A.fruticulosa,O.aciphylla,N.sphaerocarpa and C.tragacanthoides,were directly proportional to the degree of overlap of G.przewalskii niche.4) The niche overlap between other species in GPC was generally low,only a few species had a large niche overlap.
