摘　　要：对长白山区常见树种胡桃楸、黄菠萝、假色槭、白桦的1a生幼苗进行叶面积及生物量测定与分析，结果表明：叶生物量与单株生物量遵从幂函数异速生长模型Y＝aXb，a值在2．2031～7．2505之间变化，b值在0．5708～1．0563之间变化，完全符合Kleiber法则；胡桃楸的年生物产量最高，且大部分分配在树干和根部，是固碳能力较强的树种；比叶面积依次为黄菠萝（282）＞假色槭（227）＞胡桃楸（201）＞白桦（156）。Leaf area and biomass of one -year-old seedlins of Juglans Mandshurica, Phellodendron amurense, Acerpseudo-sieboldianum and Betula platyphlla were measured and analyzed , results indicated that the relationships between leaf bio-mass and individual biomass followed power function allometry model y =axb, value of a was changed from 2.203 1 ～7.250 5 whereas b was from 0.570 8～1.056 3, perfectly matching Kleiber rule .Juglans Mands hurica showed highest an-nual biomass , most of them distributed in tree trunk and roots , showing highest carbon sequestration ability .Specific leaf area was Phellodendron amurense（282） 〉 Acerpseudo-sieboldianum（227） 〉 Juglans Mandshurica（201） 〉 Betula platy-phlla（156）.
