摘要: 应用列联表的χ2检验和Spearman相关系数研究了艾比湖湿地自然保护区植物的种间联结性和相关性。依据测定结果,将艾比湖湿地自然保护区的植物划分为4个生态种组:梭梭+盐节木+白麻+盐爪爪+琵琶柴+碱蓬+花花柴+骆驼刺+绢蒿+白刺+芦苇、小獐茅+多枝柽柳+滨藜+小叶碱蓬+盐豆木+鹅绒藤+盐穗木、胡杨+白梭梭、奶浆草+甘草+西北天门冬+赖草+罗布麻。各生态种组内,物种间具备最大的种间联结性和相关性。长期的演替过程使各生态种组对生境有最大的适应能力,各自分别生活于过渡带的盐化平原低地、湖滨盐沼地、荒漠和荒漠优势种间的阳斑。今后在艾比湖湿地自然保护区植物的保护和恢复中,以整个生态种组的角度出发较单个植物的保护和恢复更为有效。

Abstract: By using the χ2-test with contingency table and the Spearman correlation coefficient, the interspecific relationships among the main plant species in Ebinur Lake Wetland Nature Reserve were investigated. The main plant species in the Reserve were divided into 4 ecological groups, i.e., Haloxylon ammodendron + Halocnemum strobilaceum + Poacynum henclersonii + Kalidium foliatum + Reaumuria soogarica + Suaeda glauca + Karelinia caspica + Alhagi sparsifolia + Seriphidium kaschgaricum + Nitraria schoberi + Phragmites australis, Aeluropus littoralis + Tamarix ramosissima + Atriplex patens + Suaeda microphylla + Halimodendron halodendron + Cynanchum sibiricum + Halostachys caspica, Populus euphratica + Haloxylon persicum, and Lactuca auriculata + Glycyrrhiza uralensis + Asparagus persicus + Leymus secalinus + Apocynum venetum. The plant species in each group had the largest connection and correlation, and the longterm evolution made each ecological group have the greatest adaptive capability to its environment. The four ecological groups lived separately in the salinized lowland plain of desert transitional zone, saline land of lakeside, desert, and the spots in desert’s dominant species in this area. For the protection and recovery of the plants in the Reserve, it would be more effective to protect and recover the whole ecological species group rather than the individual plant species.
