不同发育阶段杉木人工林林下植被的多样性
Characterization of understory community of Cunninghamia lanceolata plantations at different developmental stages
摘要
Abstract
In order to explore the regulation of understory community characteristics at different developmental stages of Cunning-hamia lanceolata plantations, species, quantities, abundance, coverage, height and basal diameter of understory vegetation at different developmental stages of C.lanceolata plantations were investigated in Xinkou Experiment Forest Farm, Sanming, Fujian Province.Results were showed that there was not significantly different in species richness ( S) among different developmental stages plantations, whereas the individual abundance (N) was of significant difference.Mussaenda pubescens Ait.f.and other shade species were preponderant in young plantation.The important position of the heliophilous species such as Emble ia rudis Hand.-Mazz., Ilex pubescens Hook.et Arn.were rising obviously in mature and overmature forest.The diversity indices of Simpson (D), Shannon-Wiener (H), Pielou ( J′) and DMc increased in mature plantation and decreased in over-mature plantation.The understory community characteristics were closely related to the developmental stages of C.lanceolata plantations.It was an effective way to improve the species diversity of undergrowth and maintain the stability of ecosystem by intermediate cutting timely.关键词
