Cercidiphyllum japonicum is an endangered and nationally protected medicinal plant species. We use multivariate methods to study ecological relations of C. japonicum communities in the Shennongjia Nature Reserve, Central China. Fifty-eight 10 m x 20 m quadrats of C. japonicum communities were randomly set up along an altitudinal gradient. Data for species composition and environmental variables were measured and recorded for each quadrat. Two-way indicator species analysis (TWINSPAN) and canonical correspondence analysis (CCA) was used in analyses. Moreover, species diversity indices were used to analyze the relationships between species diversity and environmental variables. The results showed that there were eight types of C. japonicum communities. Each community had its own compositional, structural and environmental characteristics. Variation of C. japonicum communities was significantly correlated to elevation and slope. Community variations were also related to aspect and litter thickness. Elevation and slope were revealed as important factors that influence community distribution and diversity. Species diversity showed a quadratic and negative correlation with elevation. The importance values of C. japonicum also showed a quadratic and negative correlation with species diversity. For conservational purposes, species diversity should be maintained within a reasonable range. 2018 artículo científico 0104-7760 https://www.redalyc.org/articulo.oa?id=74460167003 https://www.redalyc.org/journal/744/74460167003/ https://www.redalyc.org/journal/744/74460167003/html/ https://www.redalyc.org/journal/744/74460167003/74460167003.epub https://www.redalyc.org/journal/744/74460167003/movil 10.1590/01047760201824032499 en http://www.redalyc.org/revista.oa?id=744 CERNE application/pdf Universidade Federal de Lavras CERNE (Brasil) Num.3 Vol.24 |
