摘  要:
以内蒙古北部锡林河流域退化草地为研究对象,通过对围栏封育、免耕补播、旱作人工草地、灌溉人工草地和灌溉饲料地5种措施作用下植物生长状况、土壤水分保持作用、抗风蚀能力的试验研究。结果表明:围栏封育、免耕补播在恢复退化草地植被、提高生产力方面效果显著,是退化草地生态修复的主要措施;适地实施旱作人工草地、灌溉人工草地和灌溉饲料地面积各1hm~2,可置换出退化草地面积分别为10hm~2,18hm~2和79hm~2;通过灰色关联度进行效益评价,各种植被恢复措施之间的综合效益差异不明显,植被恢复措施实施后,综合效益均达到较高水平。

摘  要:
The degraded grassland in Xilin River watershed in the north of Inner Mongolia was selected as the research site to study the effects of restoration treatments(enclosure,reseeding,rain-fed artificial grassland,irrigated artificial grassland and irrigated fodder cropping)on plant growth,soil water conservation function and the ability of anti-wind erosion.The result showed that the enclosure and reseeding significantly improved the productivity of the degraded grassland.1ha of rain-fed artificial grassland/irrigated artificial grassland/irrigated artificial fodder field could replace 10ha/18ha/79 ha of degenerated grassland.The difference of comprehensive benefits(through grey correlation evaluation)among restoration treatments was not significant and the comprehensive benefits from all tested treatment were quite high.
