摘　　要：从吉林省红石林业局森林资源调查小班中筛选出人工落叶松林分小班,以逻辑斯蒂模型和理查德模型进行构建,并对林分生长规律进行研究。结果表明:长白山区人工落叶松林分生长呈现出"慢-快-慢"的规律,所拟合的林分生长模型检验精度均大于98%,理查德模型拟合效果较好。人工落叶松林分生长分为3个阶段,其中"前慢期"时间为0~17年,"速生期"时间为17~36年,"后满期"时间为36年之后。林分数量成熟龄为37年,其平均生长量为4.624 1 m^3。Standing forest classes of Larix gmelinii plantation were chosen from forest resources investigation classes of Hongshi Forestry Bureau. The forest growth models "Richards" and "Logistic" were constructed, and the forest growth regularities were studied. The results showed that the growth of Larix gmelinii plantation in the Changbai Mountain presented a rule of "slow-fast-slow". The test accuracy of forest growth models were greater than 98 %, the "Logistic" had a better effect. The growth of Larix gmelinii plantation was divided into three stages, the time of "pre-slow period" was 0~17 years, the time of "rapid growth period" was 17~36 years, and the time of "post-mature period" was 36 years later. The forest with the mature age was 37 years, the average growth was 4.624 1 m^3 at this time.
