| 摘 要： | 采用群落数量分类学TWINSPAN方法将油蒿群落划分为油蒿＋沙米群落,油蒿＋虫实、沙米群落,油蒿＋以沙生植物为主的杂类草群落,油蒿＋杂类草、禾草群落,油蒿＋以中生植物为主的杂类草群落共5种类型。通过对野外调查数据的分析,将群落主要影响因子压缩为土壤性状因子、物种多样性信息因子和群落生物量盖度信息因子,尝试从评价群落特征变化的角度探讨荒漠化状态评价的方法,以期为以群落水平为基础的较小尺度荒漠化状态评价提供参考,同时为退化草场的利用和管理提供理论指导。通过统计分析和适当调整,最终得出,油蒿群落的TWINSPAN分类结果能够反应目前毛乌素沙地的退化状态,可作为荒漠化程度划分的方法。

| Abstract: | With the quantitative community classification method TWINSPAN,the Artemisia ordosica communities in Mu Us Sandland were classified into five types,i.e.,Artemisia ordosica+Agriophyllum pungens community,Artemisia ordosica+Agriophyllum pungens/Corispermum heptapotamicum community,Artemisia ordosica+herbaceous vegetation dominated by desert plants community,Artemisia ordosica+weeds/gramineous grasses community and Artemisia ordosica+herbage layer dominated by mesophyte community.Based on analyzing the field s... |
