中文摘要	以民勤湖区不同年代退耕地植被调查为依据,确定自然恢复目标,提出了10种盐碱退耕地植被恢复模式,并通过各种盐碱退耕地3a后植被恢复相关指标评价选出6种良好的生态恢复模式:黄毛头封育模式(SEFM)和黑果枸杞封育模式(LEFM)为接近自然植被的恢复模式,但该模式需在灌水抚育一定年限后才能去掉灌水措施进行自然封育;"柽柳+乌拉尔甘草"(TGPM)和"柽柳+苜蓿模式"(TMPM)属纯粹人工恢复模式,需造林初期加大造林密度,在后期抚育中通过间伐措施来降低生态压力而作为一种良好的生态恢复模式;"柽柳+花花柴"(TKPM)和"柽柳+黑果枸杞"模式(TLPM)以较低的生态成本达到了较高的生态效益,是生态恢复模式最佳选择。
英文摘要	Some natural recovery objectives were set up and 10 modes of saline vegetation restoration were put forward based on vegetation survey in different years on abandoned farmland in Minqin lake regions.Six better ecological restoration models were selected by the evaluation of the relevant indicators of the model vegetation which performed in three years.SEFM and LEFM are near-natural vegetation recovery mode,but this model based on some irrigation measures in the initial three years will be near-natural recovery at the later stage.TGPM and TMPM are the purely artificial recovery models which are good for increasing the plant density in the initial planting,thinning plants at the later stage to reduce the ecological pressure.TLPM and TLPM are the best models in terms of low cost and high eco-efficiency.
