| 摘 要： | 为了揭示甘肃白水江自然保护区龙头箭竹(Fargesia dracocephala)开花后的更新及其更新苗生长特征,2019年9月对龙头箭竹开花区域的1年生更新苗的密度、基径和高度进行了调查。结果表明:(1)1年生幼苗的平均密度为21.7(±1.96)株﹒m-2、平均高度为7.94(±0.75)cm、平均地径为1.24(±0.07)mm;(2)中等程度的郁闭度、灌木层和草本层盖度均有利于龙头箭竹1年生更新幼苗的密度、基径和高度。在将来的管理中,可适当通过冠层遮阴的调控来加以管理,以加速龙头箭竹的恢复。

| Abstract: | In order to explore the regeneration after flowering and the growth characteristics of regeneration seedlings of Fargesia dracocephala in Baishuijiang National Nature Reserve of Gansu province,the density,basal diameter and height of 1-year-old regeneration seedlings after flowering of F.dracocephala had been studied.The results showed that:(1)The average density of 1-year-old seedlings was 21.7(±1.96)plants per square meter,the average height was 7.94(±0.75)cm,and the average basal diameter was 1.24(±0.07)mm;(2)Moderate canopy density and understory(shrubs and herbs)promoted the density,basal diameter and height of 1-year-old regeneration seedlings.In order to accelerate the recovery of F.dracocephala,it is necessary to regulate canopy shade in future management. |
