摘    要:自2003年开始,酒泉市3个县的荒漠化草原被列为"退牧还草"试点,对禁牧、休牧措施在植被恢复中的实际效果进行了连续的定点观测。结果表明,退牧对恢复草地植被效果明显。退牧后植被的高度、盖度、多度、地上生物量和可食牧草产量等生产性能明显提高。就植物多样性、盖度、高度和产草量的综合效应而言,采取禁牧等措施对植被恢复均存在显著的促进作用。

关 键 词:退牧  酒泉市  退化草地  生态效果  荒漠

Abstract:Since 2003,three desertification grasslands in Jiuquan City were identified as pilot of restoring grazing areas to grasslands,successive fixed-point observation were conducted on the actual effects of grazing forbidden,rest grazing.The results indicated that the effect of restoring grazing was obvious to vegetation restoration.The performance of vegetation height,coverage,abundance,ground biomass and usable grassland productivity increased remarkablly.As to plant diversity,coverage,height and grass yield,adopting grazing forbidden had significant promoting effects to vegetation restoration.
Keywords:retrieving grassland from grazing  Jiuquan City  degraded grassland  ecological effects  desertification
