| 摘 要： | 通过野外试验、室内数据整理、计算机模拟等手段,研究不同立地条件下天然落叶松生长过程变化.结果表明：不同立地条件下天然落叶松胸径生长过程拟合选出的最优方程为Richards方程;落叶松胸径、树高前5 a生长缓慢,5 a后加速生长;落叶松材积在前10a生长缓慢,10 a后加速生长;前30 a落叶松胸径、树高、材积总生长量差别表现不明显,30 a后立地条件越好,生长量越大.

| Abstract: | By field experiment, indoor data arrangement, computer simulation, growth process change of natural Larix was researched under different site conditions. DBH growth process of natural Larix in Guandi mountain forest under different site conditions was fitted to the optimal equation of Richards equation. DBH and height of Larix grew slowly in the first 5 a and grew quickly after 5 a; volume of timber of Larix grew slowly in the first 10 a and grew quickly after 10 a; the difference of DBH, height and total volume of timber of Larix was not obvions in the first 30 a and total mass growth was bigger in better site condition after 30 a. |
