【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、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．更多还原

【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· andthose of tree, shrub and herb layers are respectively 106. 150, 2. 230, 2. 264t· ha-1 and7465. 00, 223. 00, 1182. 00kg· ha-1. yr-1, each occupying by 94. 79, 1. 99, 2. 02% and83. 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.更多还原
