摘要/Abstract

摘要： 运用方差分析、X²检验、种间联结显著性等指数,对湖南吉首德夯地区的五柱绞股蓝种群所在群落内主要物种的种间关系进行分析。结果表明,群落内物种的总体关联性的方差比率为5.37,大于1,表现为显著正关联性,反映了整个群落处于稳定状态。在8个主要物种的28个种对中,18个为正相关,其中有1个显著正相关,其余10个种对为负相关。

关键词: 五柱绞股蓝, X²检验, 种间关联

Abstract: The interspecific association of companion species in Gynostemma pentagynum community in Jishou,Hunan Province was analyzed by variance analysis,X²-test and association indices.The total related variance ratio among species in Gynostemma pentagynum community was 5.37.The results indicated that there was a significant positive correlation among species,and the community was at a stable stage.Among 28 species pairs of 8 main species in the community,18 species pairs showed positive correlations,while the other 10 pairs showed negative correlations.

Key words: Gynostemma pentagynum, X²-test, interspecific association
