摘    要:在鄱阳湖沙地不同沙化程度区开展单叶蔓荆群落组成及其物种多样性变化调查.结果表明:随着沙漠化程度的增加,多年生草本和灌木逐渐减少,物种多样性减少,至重度沙化时,沙地植被明显退化,群落结构趋于简单和不均匀;在不同程度沙化区和植被恢复演替过程中,物种组成结构具有递进性和渐变性;在沙山治理过程中,可进行单叶蔓荆和禾本科植物配植...

关 键 词:沙漠化  单叶蔓荆  物种多样性

Abstract:Characterication of construction and funtions in the species,density,coverage of Vitex rotundifolia var.simplicifolia community in Poyang Lake were analyzed. An investigation was implemented at 3 successional stages,the slightly sandy land,the moderately sandy land,the highly sandy land. The species diversity indexes showed that desertification was a process of biodiversity loss. Perennial herbaceous plants and shrub were dominant at every deserted stage. The community construction trended towards simple an...
Keywords:Desertification  Vitex rotundifolia var.simplicifolia  Plant diversity
