研究了豫西日本落叶松人工林的生物量和生产力．结果表明，日本落叶松林分的生物量随林分年龄、密度、优势高的增大而增大；在同一年龄阶段，优势高对林分生物量的影响显著大于密度－２３ａ 生日本落叶松林分生物量为２４９－４３ｔ·ｈｍ － ２，生产力为１６－８３ｔ·ｈｍ －２·ａ－１ ．应用Ｗ＝ ａ（ Ｄ２ Ｈ）ｂ 估测日本落叶松人工林生物量，其相关程度达显著水平． The biomass and productivity of Japanese larch plantations in western Henan were studied. The results showed that the biomass of Larix kaempferi forest increased with the age, density and superiority of stand height. The effect of dominant height on stand biomass was significantly greater than that of density-23a Larix kaempferi forest at the same age The biomass was 249-43 t · hm -2 and the productivity was 16-83 t · hm -2 · a -1. The biomass of Larix kaempferi plantation was estimated using W = a (D2 H) b, and the correlation was significant.
