Analysis on competition and coexistence patterns of Aneurolepidium chinense and its main companion species

Abstract

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.

Key words: Competition, Coexistence, Spatial pattern, Aneurolepidium chinense, Companion species, carbon emission, carbon footprint, food security, global warming
