| 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. |
