摘　　要：对长白落叶松2年生苗在一个生长季节内高生长进行定期测量,分析苗高生长速率与同期气象因子的变化关系,结果表明:苗高生长速率与气温和露点变化趋势表现为较明显的一致;通过统计分析检验,在试验测定的气象因子中,大气温度和露点对苗高生长速率变化影响极显著,其它气象因子对高生长速率的直接影响均不显著;相关检验证明,苗高生长速率与大气温度和露点变化呈极显著的线性相关。An experimental height changed by the meteo of height changed obviously research on the Larix oligensis changbaiensis seedlings growth ve rological element was conducted. The results showed that the growth by average temperature and dew point in growth season, and it locity of velocity was not significant relative to other meteorological element, relative to the average temperature and the dew linearity with the average temperature and the dew but the other meteorological element were significant point. The growth velocity of height is significantly point.
