Discovery and Community Diversity of Ceratopteris thalictroides in Urban Parks
[Objective] To investigate the species diversity of a community of Ceratopteris thalictroides(belonging to national II level protected plants)with good growth vigor discovered in Bijiashan Park.[Method] The habitat and species diversity of C.thalictroides discovered in Bijiashan Park were studied by using sample plot investigation.[Result] There were 15 species belonging to 15 genera, 11 families in the community.The top 5 species from the aspect of important value were Ludwigia hyssopifolia (27.35), Cynodon dactylon (15.69), Murdannia triquetra(14.09), Spilanthes paniculata(8.03) and Ceratopteris thalictroides (5.96).C.thalictroides didn't take advantage role in the whole community.And three species of liana plants were also found.Simpson index (D) was 0.917, Shannon-Wiener index (H) was 2.735.Pielou index were 0.883 and 0.917 respectively, which were all higher than those of typical communities in other regions.[Conclusion] The fixed protection of this community should be suggested, and the invasive species Mikania micrantha and Pharbitis purpurea should be removed immediately.
