摘要: 用DCA排序研究了黄土丘陵区撂荒地上植物群落演替的趋势和方向,用6种多样性指数分析了物种丰富度、均匀度和综合多样性在演替过程中的变化。随着演替的进展,物种丰富性显著增高,均匀性逐渐降低,综合多样性逐渐升高。

AbstractThe Detrended Correspondence Analysis (DCA) was employed to analyze the trend and direction of plant community succession of abandoned loess land. Seven species diversity indices were used to study the changes in species richness , species evenness and diversity in the succession. With the development of succession , species richness increased significantly , species evenness decreased slightly and diversity went up.
