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、互．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．
The relative biomass and quadrat yield were used to study the biomass and productivity of the plantation community. The results showed that the total biomass and total net production of the community were 111.982 t ha-1 and 8942-80 kg ha-1 yr-1, respectively, in which the biomass and net production of arbor, shrub and herbaceous were respectively Were 106.150, 2.230 and 2.264 t ha-1 and 7465.00, 223.00 and 1182.00 kg ha-1 yr-1, accounting for 94.79% of the total respectively. 99 and 2.02%, 83.47, 2.49 and 13.22%, litter biomass 0.364 t ha-1, and stand-dry weight 0.974 t ha-1. According to the analysis, the Changbai pine plantation is in urgent need of tending thinning, adjusting the yield structure of the community, improving the overall function of the forest ecosystem, and cultivating fine fast-growing high yield forest.
