通过对福建省南平市37a生楠木人工林细根生物量季节动态及其周转的研究，结果表明，0-1mm和1-2mm两个径级楠木活细根和死细根的平均生物量分剐为2598和1960kg·hm-1、2679和1746kg·hm-1，林下植被（根径≤2mm）的平均生物量为3414kg·hm-2。0-1mm和1-2mm两个径级的楠木活细根生物量在5月份或11月份出现峰值，而林下植被生物量峰值则出现在11月份和3月份。楠木林0-1mm和1-2mm两个径级的细根年生产量分别为8167和4605k·hm-2吨，周转率分别为3．14和2．35次·a-1。研究成果可为进一步研究楠木人工林生态系统的碳循环与养分循环提供基础数据。

Through the research on seasonal dynamics and turnover of fine root biomass of 37a Phoebe bournci man-made forest in Nanping, Fujian, the results show that the average biomass of live fine root with two diameter classes being 0-1mm and 1 -2mm is 2 598 and 1 960 kg.hm-2 respectively, and that of dead fine root 2 679 and 1 746 kg.hm2 respectively, and the average biomass of understory vegetation (≤ 2mm in diameter) is 3 414 kg.hm-2. Biomass of live fine root of phoebebourme with two diameter classes being 0-1mm and 1 -2mm experiences peak value in November or May, while biomass of understory vegetation experiences peak value in November and March. The annual production of fine root of phoebebourme forest with two diameter classes being 0-1mm and 1 -2mm is 8 167 and 4 605 kg.hm-2 respectively, their turnover being 3.14 and 2.35 times.a-1 respectively. The research results can provide the fundamental data for further studies in carbon cycling and nutrient cycling of Phoebe bournci man-made forest ecosystem.
