【摘要】 在羊草种群与其它植物种群的交错区 ,应用频度、格局形式、格局强度指数对羊草及其主要伴生种之间的共存格局进行了分析 .结果表明 ,羊草及其主要伴生种的格局呈多样化 .集聚格局形式是羊草抵御外来物种入侵 ,或者是自身扩散的一种对策 .羊草与其主要伴生种之间存在竞争与共存作用 .羊草与芦苇之间通过拮抗作用实现竞争与共存 .羊草与鸡儿肠通过竞争而实现共存 .光稃茅香、碱茅以营养繁殖策略实现与羊草竞争 .拂子茅的生长受羊草竞争的抑制 .更多还原

【Abstract】 In this study,transects were set in areas where Aneurolepidium chinense and its companion species grew together.Competition and coexistence patterns of these species in the ecotone were analyzed using the following measures:frequency distribution,spatial pattern,and pattern intensity.Patterns of A.chinense and its main companion species were diverse.Aggregation was the tactics for A.chinense to defend the foreign species’ invading or disperse itself.There existed competition and coexistence between A.chinense and its main companion species.A.chinense and Phragmite communis competed and coexisted through suppression.A.chinense and Kalimeris interifolia coexisted through competition.Hierochloe glabra and Puccinellia tenuiflora competed with A.chinense through clonal growth.Calamagrostis epigeios was suppressed by A.chinense.更多还原
