| 摘 要： | 在群落样方调查基础上,采用双向指示种分析法(TWINSPAN)对子午岭地区和六盘山地区植物群落进行了数量分类.TWINSPAN将39个样方划分为7个群系.7个群系的乔木层、灌木层、草本层多样性与生产力的关系分别表现为单调下降、单调上升、不明显,群系总体多样性与生产力的关系为单调下降. |

| Abstract: | Based on the survey of community plots, a quantitative analysis of the communities in Ziwuling and Liupanshan was performed with TWINSPAN and 39 quadrates collected from Ziwuling and Liupanshan were classified into 7 types by TWINSPAN. Three patterns of this relationship between species diversity and productivity within the tree layer, shrub layer and herb layer were known, i.e, the monotonically decreasing, monotonically increasing and the unimodal. The relationship between species diversity and productivity within the total abundance of a community was of the monotonically decreaseing nature. |
