采用样带网格调查法和分层株数法,研究了不同抚育强度下的人天混红松林群落演替趋势。结果表明:透光抚育群落中红松、五角槭和胡桃楸属于潜在进展种群,裂叶榆、青楷槭和花楷槭属于潜在稳定种群,而蒙古栎属于衰退种群。不同林分均呈现进展演替趋势,向阔叶红松林方向发展。
The succession of Pinus koraiensis forest communities under different tending intensities was studied by means of transect grid survey and stratified plant number. The results showed that Pinus koraiensis, Pentagon maple and Juglans mandshurica were the most likely populations in the light-translocation and uplifting communities, while the populations of Crataegus, Cyathea macrophylla and Cyathecium glauca were potentially stable, whereas Quercus mongolica was in the declining population. Different stands show the trend of succession, to the direction of the development of broad-leaved Korean pine forest.
