摘  要:
在宁夏南部大面积分布着以长芒草(Stipa bungeana)为建群种的干草地,是重要的草场资源。为了进一步探索封育对植物群落结构和生物量的影响,从1984~1986年,在云雾山草原自然保护区内选择了因放牧、鼠害危害较严重的长芒草草地进行了封育试验。经过3年封育,长芒草群落结构已发生了显著变化,地上生物量与地下生物量成正比亦大幅度提高,为合理利用草地,保护草地,增加草地土壤肥力,发展畜牧业提供科学依据。

摘  要:
Stipa bungeama dominated grassland developes widely in the southern part of Ning—Xia, Which is also a important forage resource for animal husbandry. The experiment of effects ofenclowure on the comminity structure and biomass was carried out on the Seriously—deteriorated Stipa P. pasture within the grassland region of yun—wu mountains during 1984~1986. The results showed that after three years of enclosure, Stipa P. community structure has changed evidently, the ratio of above—ground biomass to the under—ground biomass increased greatly, Which provieds reliable data for the reasonable utilization and protection of grassland and measures for enriching soil.
