摘要
从弃耕地香茅草群落恢复演替到长芒草原生植被需要四五十年的时间，可见原生植被破坏后的自然恢复是相当缓慢的．通过补播优良牧草沙打旺和兴安胡枝子能加速植被的恢复，只需10年左右的时间即可由弃耕地或退化草地百里香群落演替到长芒草群落．
From the recoverage of Hierochloe odorata population on the wasteland succeeding tothe original vegetation of Stipa bungeana,it would spend forty to fifty years. Therefore,from theoriginal vegetation destroying to the natural recovering, it is a very slow process. The resultsindicated that vegetation recoverage was able to be accelerated by supplemental planting finepasture, Astraglus adsurgens and Lespedeza dahurica From the population of Thymus monglicuson the waste or degraded grassland to succeed to the ploulation of Stipa bungeana,it spent onlyabout ten years.
