中文摘要	于2010年49月在宁夏云雾山草原自然保护区实验区内对草地进行各种改良措施应用试验,以寻求加快宁南半干旱区草原生态恢复的关键技术。改良后的测定结果表明:草地松耙后的植物群落多样性与对照之间差异不显著(P>0.05),盖度和生物量明显低于对照,分别低7%、32.4 g·m~(-2);草地松耙、草地松耙+补播、草地松耙+施肥、草地松耙+补播+施肥、围栏封育处理后的土壤含水量与对照之间差异显著(P<0.05),容重均小于对照;草地松耙+补播+施肥的土壤养分与对照之间差异显著(P<0.05)。
英文摘要	The trial of various improvement measures of pasture was conducted in Yunwu Mountain Nature Reserve during April to September in 2010 to seek for the key technologies to accelerate the grassland ecological restoration in the semi - arid areas of southern Ningxia. The results showed that there was no significant difference in plant diversity between the treatment of harrowing and the control (P > 0.05). The coverage and biomass under harrowing were remarkably reduced by 1% and 32.4 g?m~(-2) respectively, compared with the control. The soil moisture content under the treatments of harrowing, harrowing + reseeding, harrowing + fertilizer, harrowing + reseeding + fertilizer, and fencing was significantly different from that under the control (P < 0.05), while the soil bulk density under these treatments was reduced. The content of soil nutrients under harrowing + reseeding + fertilizer was also significantly different from that of the control (P<0.05).
