科尔沁沙地不同演替阶段冷蒿群落的结构特征
Structural characteristics of Artemisia frigid community at different succession stages in Horqin Sandy Land
摘要
Abstract
Taking space as a substitute for time, this paper studied the species composition and species diversity of Artemisia frigid community at three succession stages in Horqin Sandy Land.The three succession stages were Periploca sepium-A.frigida community, Periploca sepium-A.frigida+A.halodendron community , and A.frigida-Cleistogenes squarrosa community, all dominated by the plants of Compositae, Chenopodiaceae and Gramineae.The species number and family number in the communities and the species number of Gramineae decreased with succession, while the percentages of Compositae and Gramineae species mcreased.The species diversity of the communities was in the order of P.sepium-A.frigida+A.halodertdron ＞ P.sepium-A.frigida ＞A.frigida-G.squarrosa.No obvious difference was observed in the species composition among the three communities.In the three communities, A.frigida had the highest coverage, and the coverage increased with succession.关键词
