【Abstract】 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.更多还原
