Interspecific Association of Schefflera octophylla Secondary Forest Communities in the Central Part of Hainan

摘要: 为了研究海南热带中部丘陵区鸭脚木天然次生林群落乔木层、灌木层、草本层各优势种群的种间关联性,阐明群落演替与种间关联性的内在规律,为丘陵区鸭脚木天然次生林的保护、恢复与重建提供理论依据。笔者采用2×2列联表,运用方差比率法、χ²校验、jaccard指数计算15个乔木物种、19个灌木物种和15个草本物种的总体关联性。结果表明,鸭脚木群落所有层次总体上呈不显著正联结,其中显著正关联总对数为10对,jaccard指数与χ²检验结果高度一致。海南中部丘陵区鸭脚木群落优势种种间联结松散,优势种的种间关系整体不紧密,处于动态演替的不稳定期。物种之间存在一定的独立性,整体趋向稳定发展,实践中应将正联结较强的树种加以保护,以缩短海南中部丘陵区鸭脚木群落天然次生林演替的进程。

Abstract: The interspecific associations of dominant species in the tree layer,shrub layer and herb layer in the natural secondary forest of Schefflera octophylla in the hilly tropical region of the central part of Hainan were studied in order to clarify the inherent laws of community succession and interspecific association in the S. octophylla community toprovide a theoretical basis for the conservation,restoration and re-establishment of the S. octophylla community. The overall association of 15 tree species,19 shrub species and 15 herbaceous species in the S. octophylla community was calculated by usingcontingency tables,variance ratio test,and Jacard index. The results showed there was generally no significant positive correlation between all the layers of the S. octophylla community,although there were 10 pairs of species with significant positive correlation,and the Jacard index was highly consistent with the test. The dominant species in the S. octophylla community in the hilly area of central Hainan Island were loosely correlated,and the interspecific correlation of the dominant species was not close and was at a unstable stage of dynamic succession. The plant species were somewhat separate to each other and tended to develop steadily. In practice the plant species that are highly correlated with each other should be protected in order to shorten the succession of S. octophylla secondary natural forest in the hilly area of the central part of Hainan.
