武夷山风景名胜区马尾松次生林群落数量特征变化研究

Change of Quantitative Characteristics of Secondary Pinus massoniana Community in the Process of Natural Regeneration in Wuyishan Scenery District

  • 摘要: 对武夷山风景名胜区内天然更新的马尾松次生林群落固定样地进行长期监测,应用群落统计方法分析2004—2013年景区内受人为干扰影响后更新的马尾松次生林不同群落层次的数量特征变化。结果表明,该次生群落处于演替初期,物种组成较简单,近10年更新过程中物种种类从19种增加至21种,更新速度缓慢;乔木层物种数从5种增至6种,马尾松为优势种,重要值从8030降至7644,林内伴生树种分布较为均匀;灌木层物种数虽然均为6种,但物种组成发生较大变化,经过10年演替更新,草本层发展成为以芒萁占优势的单一物种;景区茶园垦殖后的农地上马尾松群落次生演替过程缓慢,对土壤改良作用有限。建议在今后的森林经营管理中要有计划地进行适度人工干预,加速其正向演替进程。

     

    Abstract: In Wuyishan Scenery District, quantitative characteristics change in the process of natural regeneration in secondary Pinus massoniana forest community from 2004 to 2013 was studied by means of statistics of plant community methods. Results showed that in early succession of a secondary community, the species composition was relatively simple. The species increased slightly (increased from 19 to 21) and the pace of regeneration was slow in the nearly past 10 years. Tree layer species increased from 5 to 6 during 10 years and Pinus massoniana was dominant species, whose important values were 8030 and 7644 in 2004 and in 2013 respectively. The associated species in the tree layer had a homogeneous distribution pattern. Although the number of shrub layer species always was 6 species, species composition changed greatly. During 10 years of succession, Dicranopteris linearis become dominant in herb layer, which was single herbage community. The secondary Pinus massoniana forest in the process of natural regeneration was much slow in the farmland that was planted tea in the early time. We suggest that artificial intervention appropriately should be taken to accelerate the forest succession process in the future forest management.
