摘要: 根据东北沙质荒漠化地区呼伦贝尔沙地、科尔沁沙地的72个沙地植物群落样地、276种植物的调查数据,进行双向指示种分析(TWINSPAN),结合DCA排序得到符合客观实际的分类结果,初步建立了中国东北沙质荒漠化地区植被分类系统,6个植被型,11个植被亚型,40个群系,55个群丛.

关键词: 东北西部, 沙质荒漠化地区, 植被, 分类

Abstract: Based on the data obtained from 72 plant community plots and 276 plant species in Hulunbeier Sandy Land and Kerqin Sandy Land in the northeast desertification region of China,TWINSPAN analysis was carried out. Meanwhile the practical classification result was obtained by Detrended correspondence Analysis (DCA). Under the vegetation classification principles of China, the vegetation classification system of the desertification regions in northeast China was preliminarily established,which includes 6 vegetation types,11 subtypes,40 formations,and 55 associations.

Key words: West of northeast China, Sandy desertification region, Vegetation, Classification
