为揭示不同程度的人为干扰对中亚热带森林生物量及其空间分布格局的影响机制,在湘中丘陵区4种处于不同程度的人为干扰、地域相邻的植物群落:檵木-南烛-满山红灌草丛(LVR) 、檵木-杉木-白栎灌木林(LCQ) 、马尾松-石栎-檵木针阔混交林(PLL) 、石栎-红淡比-青冈常绿阔叶林(LAG)设置固定样地,结合植物群落调查,采用收获法和建立主要树种各器官生物量相对生长方程,测定和估算群落生物量。结果表明: (1)随着人为干扰程度减弱,群落总生物量呈显著的指数函数增长(P0.05) ,4个群落灌木层生物量及其各器官、地上部分、地下部分生物量均呈先增加后下降的变化特征,草本层生物量及其地上部分、地下部分生物量...

This study sought to assess the effects and underlying mechanisms of anthropogenic disturbance on biomass and spatial distribution pattern in subtropical forests in central southern China. Four types of forests were chosen in a hilly area of the central Hunan Province' China' including: 1) Loropetalum chinense-Vaccinium bracteatum.-Rhododendron mariesii. scrub-grass-land (L V R), 2) Loropetalum chinense-Cunninghamia lanceolata-Quercus fabri shrubbery (L C Q), 3) Pinus massoniana -Lithocarpus glaber-Loropetalum chinense coniferous-broad leaved m...
