摘要: 采用Shannon-Wiener多样性指数、均匀度指数和优势度指数等指标研究了辽宁东部山区人工营造20年生5种阔叶树水曲柳、刺楸、紫椴、色赤杨、白桦与红松形成的混交林及人工红松纯林内各层次高等植物物种多样性,并对该6种林分的垂直结构进行比较。结果表明,人工阔叶红松混交林内植物种类丰富,数量较多;红松纯林内的植物种数仅为人工阔叶红松混交林的42%~52%,植物总数量只有混交林的11%~37%。人工阔叶红松林各层次高等植物物种多样性均好于人工红松纯林,但与原始阔叶红松林相比,人工阔叶红松林的物种多样性还较低。在林分垂直结构方面,人工阔叶红松混交林的成层现象明显,层次结构复杂,垂直多样性丰富;红松纯林只有1个主林冠层,灌木层、草本层较矮,林分垂直结构单一。

Abstract: Employing Shannon-Wiener index,evenness,and dominant index,this paper studied the species diversity of 20-yr artificial pure and mixed broad-leaved Korean pine forest stands in eastern Liaoning Mountains.The results showed that mixed forest had a higher biodiversity than pure forest.The species and their total amount in pure Korean pine forest was 42%~52% and 11%~37% of mixed forest,respectively,and the species diversity of artificial broad-leaved Korean pine forest was higher than that of pure forest but lower than that of natural broad-leaved Korean pine forest.Artificial broad-leaved Korean pine forest had more layers with complicated structure and diversity in vertical layer,while pure Korean pine forest only had one main layer with lower shrub and herb layers,which made the vertical structure simple.
