2003-2005年,通过对青海省玉树县上拉秀乡高寒草甸和高寒沼泽化草甸退化草地进行为期3年的禁牧封育改良试验,结果表明:禁牧封育措施对恢复高寒草甸、高寒沼泽化草甸退化草地植被有明显的效果,禁牧封育后草地中植物的盖度、高度和产草量明显提高;牧草成分发生显著变化,优良莎草科、禾本科牧草种类与产量增加,杂类草的种类、产量下降。
The effect of enclosure and grazing prohibition on the improvement of deteriorated alpine meadow and the alpine swamp meadow was conducted for three years. The result indicated that this measure showed a great effect on the restoration of deteriorated grassland.
