本文进行高世代杉木种源在不同立地条件下的栽植试验，调查二年生种源的生长状况，结果表明：在坡的下、中、上部，二年生高世代杉木种源的地径（或胸径）与树高平均生长量分别为4.08、3.82、3.56 cm和1.90、1.74、1.63 m。在不同立地条件下，地径（或胸径）、树高生长量存在显著差异。
The growth status of Cunninghamia lanceolata of advanced generation provenance in their 2-years stage was investigated by planting test in different site conditions. The results indicated that their average growth of ground diameter and tree height in their 2-years stage were respectively 4.08, 3.82, 3.56cm and 1.90, 1.74, 1.63m in down-slope, middle-slope and up-slope. According to data analysis, there were also significant differences existing in the growth of ground diameter and tree height, in different site conditions.
