Having analyzed the quadrat data of several years,the paper studied the dynamic rules of biodiversity during restoration process of grassland after shallowly ploughing,and also studied the main plant populations which caused the changes.
利用多年样方资料的统计分析,对退化草原群落浅耕翻处理后恢复过程中的生物多样性变化规律及引起这些变化的主要植物种群进行研究,结果表明:退化羊草草原在浅耕翻恢复过程中其多度分布特征表现为个别种个体的快速富集(建群种)和少数种随演替进程的富集(优势种),多度很少的种类(偶见种和伴生种)增加的过程,以上特征与恢复过程中羊草的增加密不可分。
