摘要: 通过对吉林柳树河林场的集材主道、叉道的植被天然更新的调查及分析,结果表明:1)集材主道的更新树种以喜光树种香杨、柳和白桦为主,其中香杨是更新最早的树种;叉道以核桃楸和水曲柳为主。2)从更新株数、主要更新树种平均高、平均年龄及植被平均盖度上看,集材叉道西坡更新状况最好,集材主道次之,集材叉道东坡最差。

关键词: 集材主道, 集材叉道, 天然更新

Abstract: Based on the investigation and analysis of natural vegetation regeneration of main skidding road and skidding trail,the results indicate: 1) light demanders such as Populus koreana Rehder ,willow and birch are main regeneration tree species on main skidding road,and Populus koreana Rehder is the earliest regeneration tree; Juglans mandshurica and Fraxinus mandshurica are main regeneration tree species on skidding trails. 2) Based on the number of regeneration trees,the average age and the average height of main regeneration tree and average cover degree,the conditions of regeneration on west slope of skidding trail are the best,and the conditions of regeneration on main skidding road better than that of east slope of skidding trail.

Key words: main skidding road, skidding trail, natural regeneration
