摘要: 应用相对生长法和样方收获法对长白松人工林群落的生物量和生产力进行研究。结果表明,群落总生物量和总净生产量分别为111.982t·ha-1和8942·80kg·ha-1·yr-1,其中乔木层、灌木层和草本层生物量和净生产量分别为106.150、2.230和2.264t·ha-1及7465.00、223.00和1182.00kg·ha-1·yr-1,分别占总量的94.79、1.99和2.02%及83.47、2.49和13.22%,凋落层生物量0.364t·ha-1,立枯量0.974t·ha-1.经分析可得,长白松人工林急待进行抚育间伐,调整群落产量结构,提高森林生态系统的整体功能,培育优良速生丰产林。

Abstract: Studies on biomass and productivity of Pinus sylvestriformis plantation with relativegrowth and quadrat-harvesting methods show that the total biomass and the total net production of the community are respectively 111.982t·ha-1 and 8942.80kg·ha-1·yr-1, and those of tree, shrub and herb layers are respectively 106.150, 2.230, 2.264t· ha-1 and 7465.00, 223.00, 1182.00kg· ha-1·yr-1, each occupying by 94.79, 1.99, 2.02% and 83.47, 2.49, 13.22% of the total.The biomass of littet layer is 0.364t· ha-1 and that ofdead standing tree is 0.974t·ha-1.These data show that tending felling must be taken to regulate the production structure of the community, to enhance the integrated functionsof forest ecosystem and to breed an excellent fast-growing and high-yield forest.
