【摘要】 通过对长白山西部50年代择伐过的阔叶红松林早春阶段(4月25~29日)草本植物的调查,结果表明其Shannon-Wiener多样指数、种数及个体总数明显与坡向、坡位有关,明显呈阴坡高于阳坡、坡上低于坡下的趋势。早春草本层植物物种多样性较丰富,但要低于原始阔叶红松林,在所调查的108个样方中有早春草本层植物33种,且分布比较均匀。
【Abstract】 According to an investigation in early spring(25—29 April),the diversity of early spring herbs in broad-leaved Korean pine forest in west Changbai Mountain was found to be rich and had a great change at different slope positions.The community evenness and community similarity are also studied.
