对“黑土滩”退化草地上种植生长第5年的青海草地早熟禾(Poapratensis姒Qirtghai)人工草地进行围栏封育,封育期为5年,以冷季放牧利用的青海草地早熟禾人工草地为对照,分析土壤种子库特征。结果表明:禁牧封育使5龄青海草地早熟禾人工草地土壤种子库的物种数、密度、土壤种子库潜存群落的稳定性和放牧利用价值均有所降低,而土壤种子库潜存群落的物种多样性相对提高。
對“黑土灘”退化草地上種植生長第5年的青海草地早熟禾(Poapratensis姒Qirtghai)人工草地進行圍欄封育,封育期為5年,以冷季放牧利用的青海草地早熟禾人工草地為對照,分析土壤種子庫特徵。結果錶明:禁牧封育使5齡青海草地早熟禾人工草地土壤種子庫的物種數、密度、土壤種子庫潛存群落的穩定性和放牧利用價值均有所降低,而土壤種子庫潛存群落的物種多樣性相對提高。

Enclosure management on the growth of planted fifth year of Poa pratensis cv. Qinghai cultured grassland growing on Black Soil Beach for 5 years, the characteristics of soil seed bank were studied with Poa pratensis cv. Qinghai cultured grassland which was grazed in cold season "as controlgroup. The results showed that: Enclosure measures made the species and density of the growth of planted fifth year of Poa pratensis cv. Qinghai cultured grassland reducing, the stability and grazing use value of protencial community of soil seed bank were reduced, the species diversity of protencial community of soil seed bank increased.
