摘要

采用一次性同时调查的方法获得数据, 用数量分类( T WIN SPAN) 和排序( DCA ) 研究严村低中山植物群落演替。在黄土弃耕地上群落的演替顺序为:苦苣 +狗尾草群落( Comm. Ixeris chinensis ssp.versicolor + Setaria viridis)→蒿类群落( Comm. Artemisia spp.) →野艾蒿+披碱草群落( Comm. Artemisia lavandulaefolia + Elymus dahuricus) →披碱草+早熟禾+蒿类群落( Comm. Elymus dahuricus + Poa annua + Artemisia spp.) →沙棘灌丛群落 ( Form. Hipporphae rhamnoides ) →油松林( Form. Pinus tabulaeformis ) →华北落叶松林 ( Form. Larix principis-rupprechtii) 。 在群落演替的进程中, 群落结构 、种类组成、生活型都发生着规律性的变化。

Abstract

:Succession data w ere collected in different succession stages simultaneously and analyzed by
using quantitative classification method ( TWINSPAN) and ordination technique ( DCA ) in Yancun low-middle hills of Lǜliang Mountains.The succession series of plant communities from abandoning croplands of loess soils are: Comm. Ixeris chinensis ssp .versicolor + Setaria viridis  →Comm. Artemisia spp . →Comm. Artemisia lavandulaefolia + Elymus dahuricus  →Comm. Elymus dahuricus + Poa annua + Artemisia spp . →Form. Hipporphae rhamnoides  →Form. . Pinus
tabulaeformis  →Form. Larix principis-rupprechtii .The structure, composition and life form. change obviously during the succession .
