摘要/Abstract

摘要： 采用双向指示种分析法(TWINSPAN)和除趋势对应分析(DCA)对弄拉峰丛洼地恢复演替植物群落进行数量分类和排序。TWINSPAN将20个样方分为10个组,根据植被分类的原则划分为10个群丛,论述了各群丛的群落学特征。20个样方的DCA排序结果反映了恢复演替群落与环境梯度的关系,表明影响群丛分布格局的主导生态因子为恢复时间、人为干扰及露石率。DCA排序将53个种分为4个种组,影响峰丛洼地恢复演替群落及其物种分布格局的主导生态因子为恢复时间、岩性和水分等。各物种在排序轴上的位置反映了种组成员的生态适应性及其在群落中的重要性和更新生态位。

关键词: 恢复演替, 植物群落, TWINSPAN分类, DCA排序, 弄拉, 峰丛洼地

Abstract: Restoration succession plant communities in NongLa peak-cluster depression were analyzed by the methods of Two Way Indicators Species Analysis (TWINSPAN) and Detrended Correspondence Analysis (DCA) in this paper.Based on the vegetation systematic principle,20 plots were divided into 10 associations by TWINSPAN to describe their community characteristics.The relationship of restoration succession community and environment grades was given by the DCA result of 20 plots,which showed that the main ecological factors influencing distribution patterns of associations were resume time,human disturbance and bare rate.Moreover,53 species were classified into 4 groups by DCA.The main ecological factors influencing restoration succession communities and their distribution pattern of species were resume time,lithology,moisture and so on.The ecological adaptability of groups and their significance and regeneration niche in communities were reflected by the position in the taxis of all species.

Key words: restoration succession, plant community, TWINSPAN classification, DCA ordination, NongLa, peak-cluster depression
