摘　　要：落叶松是一个分布广,易栽培,早期生长快的树种,因此,研究落叶松幼、中龄林主要测树因子的生长规律,对落叶松的早期管理有着很重要的指导意义。结果表明,落叶松幼、中龄林的主测树因子呈幂函数型生长曲线,其直径平均生长量多在0.4 cm以上,树高平均生长量均在0.4 m以上,而在20 a后,材积平均生长量高达0.002 m3。Larch is a tree species that is widely and easily planted,so it is important for early management to study growth pattern of principal measurement factor in young- and middle-aged stands. Studies showed that the principal measurement factors of larch presented the curve of power function in young- and middle-aged stands, the average growth of diameter was 0.4 cm,height was 0.4 m and volume was 0.002 m^3 in middle-aged stands.
