| Abstract: | Based on surveyed data related to stand of three different regeneration patterns in harvest slash of secondary forest in Dalaoling national-forest-farm of Yichang in Hubei, analyzed the stand composition from three aspects of stand group of different regeneration pattern from tree species composition, vegetation under forest and tree growth; analyzed physical characteristic from moisture and fertility situation of forestry land and drawn following conclusion: 1. The stand composition of different regeneration pattern and fertility of forestry land are obviously different; 2. What regeneration of harvested slash of secondary forest formed artificial plantation performs non-stable. |
