常德油茶次生林林下植被物种多样性调查

Undergrowth vegetation species diversity survey in Camellia(Camellia oleifera) secondary forest in Changde

针对一些油茶次生林的经济价值日益降低的现状,以油茶林物种多样性为手段,量化油茶次生林生态价值。研究以常德市鼎城区2片油茶次生林为固定样地,采用样方调查法对油茶次生林林下植被物种多样性现状进行调查分析。调查结果表明:油茶林林下植物隶属于35科50属51种。其中灌木层23科33属34种,占66.67%;草本层13科17属17种,占33.33%。本研究中油茶次生林林下植被物种多样性丰富,有较多经济物种。建议在油茶人工林栽植过程中,维护油茶林林下物种多样性,兼顾复合生态经营,以获取次生林最大的经济价值。

In view of the present situation of the economic value of some of Camellia oleifera forest secondary forest are decreased with time, deeply and rightly understanding of Camellia oleifera forest species diversity is essential. It is also an important part of improving the ecological value system is quantify the species diversity. Choose 2 pieces of camellia secondary forest plots in Dingcheng District of Changde city, the Camellia secondary forest status of undergrowth vegetation diversity were surveyed by using quadrat method. The results showed that： the community samples record 35 families 50 genera and 51 species of plants. The shrub layer, 23 families, 33 genera, 34 species, accounting for 66.67%, 13 species of herb layer, 17 genera and 17 species, accounting for 33.33%. As the result, the suggestions were presented that consider ecological management and maintain species diversity should be used during Camellia plantation process. It is necessary to take into account the complex ecological management, to maximize the economic value of secondary forest.
