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 8030 and 7644 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.
