科尔沁沙地恢复演替进程中群落物种多样性与地上生物量的关系OA北大核心CHSSCDCSCDCSTPCD
Relationship between the aboveground biomass and species diversity of sandy communities during the process of restoring succession in the Horqin Sandy Land, China
生物多样性与生产力的关系是当前生态学中研究的重点之一,以科尔沁沙地为研究对象,研究了沙地植被恢复演替进程中物种多样性与地上生物量的关系.结果表明:(1)科尔沁沙地植被恢复演替过程中,物种数量逐渐增加,从流动沙丘的6种到固定沙丘的30种,增加了4倍.一年生草本植物在各群落中占绝对优势,但随着演替的进行,生活型呈现多样化,多年生植物种类明显增加.藜科植物在流动沙丘阶段优势度明显,之后逐渐下降;禾本科植物的种数和优势度逐渐增加,在群落中的地位逐渐增强.…查看全部>>
The relationship between species diversity and aboveground biomass may be affected by environmental conditions and anthropogenic activities and is one of the central topics in ecological research.However,little is known about the relationship between the biodiversity and biomass of sandy plants during community succession in semi-arid deserts.In the Horqin Sandy Land of Inner Mongolia in China,vegetation restoration occurs under proper management regimes in …查看全部>>
