摘要
本研究以云南省马龙县山地草甸为研究对象,对封育的退化草地刈割后植物群落的变化进行了测定和分析。结果表明:刈割一年后,各刈割小区的盖度、物种数以及再生强度均呈下降趋势,而杂类草有明显的增长趋势。这说明连续的刈割会导致草原植物群落向逆向方向演替。所以,围栏封育的草地利用应每年刈割1~2次为宜。
This paper analysed the change of Plant community in different degraded stages upland meadow in Malong regions of Yunnan Province. The results showed that Mow one year later, respectively mow the plot the degree of cover, the species number as well as the regeneration intensity assumes the declining trend, but the mixed kind of grass has the obvious growth movement. This indicated that the continual mow can cause the psilophytes community to the reversion direction succession. Therefore, the railing seals the lawn use which nurtures should every year mow 1 -2 times to suitably.
