摘要

基于长白山阔叶红松林1 hm~2固定样地,于2006年5月、7月、10月调查样地内的草本植物,分析了草本植物季节变化。结果显示,样地内共调查到草本植物85种,隶属于30科68属。物种组成受季节性水热条件所主导,随季节变化明显。草本植物总株数受林下光照条件所主导,随上层林木树冠郁闭而减少。
        The herbaceous plants in the 1 hm~2 fixed plots of Pinus koraiensis forest were investigated in May, July and October 2006 to analyze the seasonal variation of herbaceous plants.The results showed that 85 species of herbaceous plants belonging to 68 genera and 30 families were investigated. The species composition which was dominated by seasonal water and temperature conditions varied significantly with season. The total number of herbaceous plants was dominated by the illumination conditions under the forest, and decreased with the canopy density of the upper forest.
