| 摘 要： | 以京承三期边坡植被恢复养护工程为案例分析了刈割的环境效应及对边坡植被群落内灌木生长的影响。结果表明,刈割对植被层3个主要环境指标的影响程度从大到小依次为:光照强度>相对湿度>温度,刈割可以显著增强植被层内部的光照强度,降低植被冠层相对湿度,增加地表温度。7、8月刈割后光照强度分别增加了3倍和7倍。同时,刈割显著促进了样方内胡枝子和紫穗槐2种灌木的生长,其中,对紫穗槐的生长促进作用显著大于胡枝子,刈割样方紫穗槐地上生物量增加幅度为138.27%,胡枝子地上生物量增加幅度为43.82%;且表现为株高越小,促进作用越明显。

| Abstract: | The paper studied the environmental effect of mowing and its impact on the shrub growth on the slope of Beijing-Chengde Phase III expressway.The results showed that the rank of impact indicators of mowing on the vegetation were light intensity>relative humidity > temperature.Mowing can significantly increased the light intensity inside vegetation,reduced the relative humidity of vegetation canopy and increase surface temperature.The light intensity has increased three and seven times in July and August after mowing.Meanwhile,Mowing significantly contributed to the growth of amorpha fruticosa and lespedeza in the sample sites,on which the growth-promoting effect of amorpha fruticosa is significantly greater than lespedeza,In sample site,the increased rate of biomass of amorpha fruticosa and lespedeza were 138.27% and 43.82%.The growth-promoting effect was obvious as the plant height was lower. |
