| 摘 要： | 在野外调查的基础上,应用TWINSPAN和DCA对太行山南端野皂荚植物群落进行了分类与排序研究.结果表明:TWINSPAN将野皂荚植物群落划分为6个群丛,分别是野皂荚+荆条-中亚苔草+荩草群丛、野皂荚+荆条+小叶鼠李-中亚苔草+荩草群丛、野皂荚+荆条+毛黄栌-冰草+中亚苔草群丛、野皂荚+荆条+小叶鼠李-白羊草+冰草群丛、野皂荚+荆条+小叶鼠李-中亚苔草+荩草群丛和野皂荚+毛黄栌-中亚苔草群落.样方和种的DCA排序结果表明,样方的DCA第一排序轴表明决定群落分布的是坡向,从阳坡过渡到半阳坡;种的DCA第一排序轴主要反映了物种生活型的变化,即由中生植物为主过渡到以旱中生植物为主.样方和种的DCA的第二排序轴生态学意义不明显,主要是研究区域尺度较小,群落异质性不明显所致.

| Abstract: | Based on the dataset,including 40 quadrats,from the filed in the southern tip of Taihang Mountains,Shanxi,the quantitative classification and ordination of Gleditsia heterophylla communities were studied by using TWINSPAN and DCA,respectively.According to the results from TWINSPAN and the principle and methodology of vegetation classification from Vegetation of China,the Gleditsia heterophylla communities were classified into 6 associations,including Ass.Gleditsia heterophylla+Vitex negundo var.heterophylla... |
