| 摘 要： | 根据草地植被群落发展规律,利用数学和统计学、投入产出法等方法,对高寒草甸类不同退化状态草地自然恢复和人工恢复进行了经济预测和效益比较,数据证明：在重度→中度恢复中,人工恢复较自然恢复效益高;在中度→轻度恢复中,自然恢复较人工恢复效益高,为草地建设科学决策提供了可靠依据。

| Abstract: | Economical estimation and beneficial prediction comparison for alpine meadow restoration at different stages of degradations by artificial measures or natural approach were carried out.The result showed that for heavily to medially degraded meadow,artificial restoration measures generate high benefit of restoration;while for medially to lightly degraded meadows,natural restoration generate high effect. |

| Keywords: | Naturally degraded meadows restoration approach economy comparison |
