| 摘 要： | 通过对川西北草原退牧还草工程区围栏草地植被恢复效果的研究，结果表明，退化草地经围栏禁牧和休牧后，由于有效消除了放牧干扰，草地得到休养生息，开始不断改善和恢复，植物种类和数量增多，物种多样性提高，样地的物种多样性大小表现为：休牧＞禁牧＞对照；围栏样地地上生物量增加明显，平均比对照高出50.36%～88.77%；草群高度也明显增高，比对照平均高出36.79%～76.98%；草地总盖度变大，禁牧和休牧草地分别比对照提高了11.49%～17.28%。同时，草地质量明显提高，优良牧草开始增多，而毒杂草的种类和数量开始减少。综合评价，各年度退牧还草工程区内草地植被生态恢复效果良好。

| Abstract: | This paper studied restoration effects of enclosed pasture in pastureland rehabilitation areas in northwestern Sichuan province, which showed that degraded grassland started to restore and improve progressively because of eliminating grazing interference after prohibiting grazing and resting grazing. Plant variety and quantity increased, the species diversity enhanced by resting grazing > forbidden grazing> control. The above ground biomass in the fenced plot was increased significantly，50.36%～88.77% higher than control. Also the height of plant community significantly improved by 36.79%～76.98%, and the total coverage was also increased by 11.49%～17.28%. The excellent forage plants started to increase while those poisonous declined. The comprehensive evaluation indicated that restoration effect of enclosed pasture in pastureland rehabilitation areas was quite good. |
