| 摘 要： | 以云南省马龙县山地草甸为研究对象，对封育3年的退化草地地上植物量和地下植物量的变化进行了测定和分析。结果表明，各退化梯度的草地在封育3年后均得以不同程度的恢复，但草地恢复效率差异很大，按草地恢复效率大小排序结果为：重度退化〉中度退化〉轻度退化。封育明显提高了退化草句群落的地上、地下植物量，各退化梯度草地封育区地上植物量增加速度排序为：重度退化〉轻度退化〉中度退化；各退化梯度封育区地下植物量增加速度排序为：重度退化〉中度退化〉轻度退化。

| Abstract: | changes of aboveground and underground biomass of different degraded stages in upland meadow under fencing condition were analyzed in Malong County of Yunnan Province.The results showed that the three degraded stages upland meadow had been improved in some extent after three years fencing,but the grass coverage efficiency were obviously different:Heavy degraded plots>mid degraded plots>light degraded plots based on revegetation efficiency.Compared to control,fencing can improve significantly aboveground and... |
