辽东山区林下人参种植地草本层片群落结构特征研究

林下人参种植地的伴生植物对人参生长很重要,因此,研究种植地草本植物群落结构及其特征对林下参种植具有十分重要的意义.本文使用多样性指数、群落均匀度、生态优势度等多项指标,对不同林分类型林下人参种植地块草本植物群落结构进行调查研究,结果表明阔叶杂木林林内的草本植物分布均匀,且层次结构明显,多样性指数及群落的均匀度比较高,生态优势度比较低,此林分类型下的人参长势明显优于其它林分类型,这种群落特征可能给林下人参的生长创造了适宜的生态条件.

A Study on Community's Structure and Characteristics of Herbage Layer Planting Ginsengs under Forest in Mountain Areas in Eastern Liaoning

An investigation on community's structure of vegetation planting ginsengs under different forest types was carried using diversified index, the evenness of community, ecological dominance etc. The rasults indicated that in the brush with broad leaf the herb is distributed evenly and has an obvious hierarchical structure, the higher diversified index and the evenness of community, the lower ecological dominance. The growing situation of the ginseng is obviously superior to other forest types.
