| 摘 要： | 采用样带网格调查方法和α多样性指数分析方法，研究了透光抚育（全透光、半透光、未透光）对辽东林区人天混红松林群落、草本层、灌木层和乔木层的植物多样性（丰富度、均匀度和多样性指数）的影响效果，结果表明：半透光群落物种丰富度最高（43），全透光（33）及对照群落（37）相接近。而均匀度和多样性指数均呈现出全透光群落（0．5862和2．0498）〉半透光群落（0．3976和1．4954）〉对照群落（0．2609和0．9421）。可见，全透光对维持人天混红松林群落的植物多样性效果更好。半透光和全透光群落多样性沿着坡位梯度呈现有规律的变化。半透光群落物种丰富度变化不大（沿自下而上的坡位梯度分别为43、43和46），而均匀度和多样性指数均呈现出上坡（0．4617和1．7677）〉中坡（0．4614和1．7354）〉下坡（0．3976和1．4954）的趋势。全透光群落物种丰富度变化也不大（沿自下而上的坡位梯度分别为33、38和36），而均匀度和多样性指数均呈现出下坡（0．5862和2．0498）〉上坡（0．5508和1．9739）〉中坡（0．5170和1．8805）的趋势。因此，透光抚育对人天混红松林植物多样性的影响还受立地条件制约。

| Abstract: | An experiment was conducted to study the effect of crown thinning(strong thinning,moderate thinning,no thinning)on richness,Shannon-Wiener index and evenness of community,herb layer,shrub layer and tree layer of Korean pine plantation with broadleaved auxiliary species in Eastern Forest Region of Liaoning using line transect methods and diversity index analysis.Results showed that the species richness index of the moderate thinning community reached the highest value of 43,and the species richness index of ... |
