摘  要：
对科尔沁沙地植物再生沙障人工群落的物种组成、生活型结构及群落多样性及其动态进行研究。结果表明:在流动沙丘上建立植物再生沙障,不仅固定了沙丘,而且也为植物的入侵和定居创造了条件。沙障建植后第3~7年的人工群落,其物种及其科属组成以及科属组成与对照流动沙丘(群落)相比都有显著的增加。物种的丰富度指数和多样性指数都呈对数式增加趋势,且变化幅度不大,表明沙障群落的物种和多样性演替比较平稳。群落的均匀度呈二项式的"V"字型变化趋势,这种变化反映了沙障人工群落人工栽植物种占据优势地位的特性以及群落内部的变化特点。

摘  要：
This study was carried out to research sandy barrier artificial community of Korqin on its species composition,life form structure,ecological diversity and their dynamics change.The results revealed that renewable plant sandy barriers built on the shifting dune not only contributed in fixing dune,but also facilitated the conditions for other plants invasion and establishment.Species genera and their compositions in artificial community built with sandy barrier plants,were found increasing significantly compared to those on control shifting sandy dunes 3~7 years later.The species richness and diversity index tended to increase in logarithmic form with slightly varies,which suggested the species and diversity succession go stable.Community evenness index was shown in binomial distribution with"V"style,which reflected the dominant character of artificial community plants built on sandy barrier and the diversification trend in community.
