摘　　要：用多元回归方法分析了白哺鸡竹的笋—幼竹生长与气象因子的相关性。“多对多”逐步回归分析表明,对笋—幼竹高生长起主导作用的因子是温度指标,对笋昼夜高生长差起主导作用的因子是大气相对湿度,降水对其生长的影响作用在时间上有滞后现象。用“一对多”线性回归给出了气象因子对笋—幼竹生长的线性回归模型。用多项式非线性回归分析表明,单个气象因子对笋高生长的作用效应是非线性的。This paper deals with shoot-culm growth of Phyllostachys dulcis in relation to the temperature and relative humidity in a newly established stand. The investigation was conducted in March and May, 1989. The main results of the nested multiple regression of meteorological factors to shoot growth show that the key factor affecting the shoot growth is temperature, while the shoot growth is not synchronized with rainfall.
