摘　　要：为了探究草地恢复过程中植被数量特征的变化规律,笔者对3年间车辙碾压草地植物群落样地的盖度、高度、密度、地上生物量、物种数、鲜重和干重的变化数据进行比较分析。结果表明:(1)封育、刈割2种处理方式使车辙碾压草地群落的各项指标均有增长的趋势且群落趋向稳定;(2)对比封育和刈割2种处理方式,封育草地年度间各项指标差异不显著(P>0.05),而刈割草地年度间的盖度(P<0.01)和密度(P<0.05)的指标差异显著。试验结果表明,通过对比封育样地和刈割样地车辙碾压群落的恢复情况,2种处理方法差异并不显著,且对群落演替影响不大。In order to study the grassland vegetation change characteristics, during the three years, area rutting meadow plant community coverage, height, density, the biomass above ground, species number, fresh weight and dry weight of the variation in the data analysis, the results show that： （1）seal breeding, cutting two treatment the and the index of grassland communities of rutting area were growth trend, and the community structure tended to be stable. （2）comparison of fencing and mowing two treatment, education annual grassland difference of each index is not significant, and mowing inter annual differences in some indicators significantly.The results showed that there was no significant difference between the two treatment methods by comparing the restoration of rut compaction communities be- tween fenced plots and clipped plots, and the two treatments had little effect on community succession.
