摘  要:
【目的】探讨春秋场草地退化演替规律。【方法】群落特征和植被数量分析。【结果】春秋场草地退化严重,不同退化梯度间的多样性呈现一定的规律性。【结论】群落多样性呈现出轻度退化>中度退化>重度退化>极度退化的规律,均匀度呈现中度退化>轻度退化>重度退化>极度退化;群落退化直接影响物种多样性变化;同时,中度、重度退化阶段属于不稳定阶段。

摘  要:
【Objective】Based on the investigation of Spring-Autumn deteriorate grassland communities,【Method】species community characteristics and vegetation quantity were analyzed,the findings from the analysis are follows: there are regularity between the community Diversity index.The community deversity were as follows:LD>MD>HD>ED and the homogeneous degree were as follows:MD>LD>HD>ED;meanwhile,heavy and moderate-degraded were unstable period of degradation.
