摘　　要：基于森林资源调查数据分析西山林场油松人工林生物量多年动态变化情况,结果表明:2004-2014年,油松人工林以近熟林和成熟林为主,成熟林面积和生物量大幅增长,幼龄林、中龄林、近熟林面积和生物量明显减少,单位面积生物量及生产力最高的立地类型为低阴中松,单位面积生物量按大小排序:阔叶混交林>针阔混交林>针叶混交林>针叶纯林。Based on the forest resource survey data, the analysis of the biomass dynamics of Pinus tabulaeformis plantations in Xishan Forest Farm over many years, the results showed that from 2004 to 2014,Pinus tabulaeformis plantations were mainly near-matured and mature forests. The area and biomass of aged forests and near-mature forests were significantly reduced. Biomass per unit area was sorted by size:broad-leaved mixed forest> coniferous-broad mixed forest> coniferous mixed forest> coniferous pure forest.
