摘　　要：长白落叶松苗木的苗高和地径生长呈典型的logistic数学模型曲线;苗高和地径的生长之间呈指数相关;苗高生长量与生长期间大于10℃的日均温度呈线性相关;而且各个模型的相关系数都达到了显著水平;苗高和地径的生长速度变化与生长期间的日平均温度变化趋势较为一致。Growth rhythm of Larix oligensis changbaiensis seedlings were applied to study, the results were showed as the followings： firstly, height growth and collar diameter of seedlings were significantly logistic model; secondly, height and diameter growth were significantly exponential functional relation; thirdly, height was significantly linearity with diurnal average temperature, and every coefficient was significantly; the lastly, the growth velocity of height and diameter changed obviously by diurnal average temperature in growth season.
