| 摘 要： | 以佳木斯市孟家岗林场长白落叶松13~18 a生人工幼龄林为研究对象,进行单木活树皮、死树皮(黑树皮、红树皮)的生物量和氮、磷、钾养分分析。结果表明:带皮胸径(x)与去皮胸径(y)的关系为:y=0.942 7x-0.110 5(R2=0.996 8,p0.001);树高或胸径虽然能够用于预测单木各类树皮生物量和树皮中氮、磷、钾贮量,但在对具体林分进行估测时,仍需考虑立地条件。幼龄林树皮总量为4 427.99~6 464.38 kg.hm-2,其中活树皮为1 745.44~3 165.39 kg.hm-2。幼龄林树皮中氮、磷、钾贮量分别为5.119~68.154 kg.hm-2、2.760~36.494 kg.hm-2、4.163~52.839 kg.hm-2,其中活树皮中氮、磷、钾贮量分别为3.981~48.941 kg.hm-2、1.908~23.552 kg.hm-2、3.359~42.079 kg.hm-2。 |

| Abstract: | Bark is an important component of trees,whose production and litter play an important role in the biogeochemical cycle of forest ecosystem.We made a survey on the bark biomass and bark nutrient storage on live stumpage and bark-litter in the young-aged larch plantation（Larix olgensis）.The result showed that the relationship between DBH with bark（x） and no-bark DBH（y） could be described by the following regression equation： y=0.942 7x0.110 5.Although the tree height and DBH could be used to predict bark biomass and bark nutrient storage of individual tree,site condition should also be considered in that prediction for specific-site forest.Total bark biomass in young-aged larch plantation was 4 427.996 464.38 kg·hm-2,including 1 745.443 165.39 kg·hm-2 living bark and 2 342.18-3 298.99 kg·hm-2 dead bark.Nitrogen,phosphorus and potassium storage in bark of larch plantation was 5.11968.154,2.7636.494 and 4.16352.839 kg·hm-2,respectively,while 3.98148.941,1.90823.552,3.359-42.079 kg·hm-2 was in living bark,respectively. |
