摘要
本文研究了科尔沁沙地草场差巴嘎蒿—杂类草群落的沙漠化演变特征。结果表明,随着沙漠化的发展,群落的植物组成种类、密度、高度、盖度、豆科和禾本科牧草产量均明显下降,草场植被急剧退化。草场植被退化的程度取决于土地沙漠化的程度。
Succession characters of desertificaton of Artemisia halodendron community in Kerchin sandy land are analysed in this paper. The result shows the plant quantity,density,height,coverage and overground biomass of biomass of grasses and legumes in the community declined obviously with developing of desertification. The desertification degree of vegetation varies according to that of the land's desertification.
