| 摘 要： | 研究中国林业科学研究院热带林业实验中心28年生红椎纯林、马尾松纯林以及红椎-马尾松混交林的生物量和生产力分配格局.结果表明:红椎纯林、马尾松纯林与红椎-马尾松混交林生物量分别为94.797,212.435和155.638 t·hm-2;3种林分的乔木层生物量均占林分生物量的95％以上,其他各层均表现为凋落物层(0.56％～3.26％)＞草本层(0.24％～0.85％)＞灌木层(0.25％ ～0.37％)；在3种林分的乔木层各组分中,干材生物量最大,占总生物量的49.31％ ～ 62.25％,红椎纯林中其他组分表现为根(17.16％)＞枝(11.76％)＞干皮(6.84％)＞叶(1.99％),而马尾松纯林与红椎-马尾松混交林则为枝(18.39％ ～ 19.98％)＞根(14.48％ ～17.72％)＞叶(5.55％～8.80％)＞干皮(4.19％ ～ 5.57％)；3个林分的净生产力表现为红椎纯林(3.369t·hm-2a-1)＜红椎-马尾松混交林(5.628 t·hm-2a-1)＜马尾松纯林(7.781 t·hm-2a-1).

| Abstract: | The three 27-years old plantations,mixed stand of Pinus massoniana and Castanopsis hystrix(MCP),pure stand of Pinus massoniana stand(PPS) and pure stand of Castanopsis hystrix stand(PCS),were investigated in the Experimental Centre of Tropical Forestry,Chinese Academy of Forestry which located in Pingxiang County of Guangxi.By harvesting and measuring the average diameter of trees collected from the above three stands,we established a group of allometric growth equations to estimate their allocation pattern... |
