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。
Through the investigation and analysis of natural renewal of the main and fork pruning of the main timber and fork for the Liushuhe forest farm in Jilin Province, the results showed that: 1) The regenerated tree species of the main timber trunk were mainly fragrant poplar, willow and white birch, Is the earliest species of tree regeneration; fork to Juglans manshurica and Ash mainly. 2) From the update of the number of trees, the average update of the main species, the average age and the vegetation cover, the status of the west slope of the strait fork channel is the best, followed by the main trunk channel, and the east slope of the skidding channel is the worst.
