| Abstract: | The 2.5 year-old broad-leaved forest by artificial measures promoting regeneration (AMPR) in Xiyang Town of Yong'an City, Fujian Province was formed after clear cutting of 35 years.old natural broad-leaved forest.Its stand average DBH, height, density, growing stock and annual increment were 2.0 cm, 1.8 m, 19 533 株/hm2, 7.0 m~3/hm~2 and 2.80 m~3/(hm~2·a) respectively.Its species richness (R), Shannon-Wiener index (SW), evenness (E) and ecological dominance (ED) in arbor storey were 33, 2.93, 0.62 and 0.21 respectively.Its relative distribution of DBH was from 0.23 to 3.00 and was showed as the distribution of uneven aged forest.The stand average DBH, height, density, growing stock and annual increment of the original forest before clear cutting were 13.6 cm, 10.5 m, 1 185 N·hm~2, 101.3 m~3/hm~2 and 2.89 m~3/(hm~2·a) respectively.The species richness (R), Shannon-Wiener index (SW), evenness (E) and ecological dominance (ED) in arbor storey were 24, 3.72, 0.81and 0.10 respectively.The relative distribution of DBH was from 0.44 to 2.50 and was showed as the distribution of uneven aged forest. |
