不同强度人为干扰对马尾松地上部分生物量及生产力的影响
Effect of different human-caused disturbances on above-ground biomass and productivity of Pinus massoniana forests
【摘要】 采用平均标准木法及分层切割法研究了不同干扰强度对马尾松林地上部分生物量和生产力的影响 ,并对 3个林分蓄积量、各器官相对比例进行了比较分析 .结果表明 ,马尾松林分地上部分总生物量、各器官生物量及净生产力均随干扰强度的减轻而增加 ,轻度干扰有利于林分生物量和蓄积量的积累及生产力的提高
【Abstract】 The influence of human caused disturbance on above ground biomass and productivity of Pinus massoniana is studied by adopting the "divided storeys" method and the mean tree method.The stocked volume and relative proportion of various organs are also compared.The results indicate that above ground total biomass and various organs and productivity increased with the decrease of disturbance intensities.Slight disturbance contributes to accumulate forest biomass and volume and promote the productivity.
