摘　　要：通过对黑龙江青山林场人工落叶松复层林解析木的分析,拟合了人工落叶松复层林上层木生长方程。分析了复层林上层木的生长过程,探讨了上层木蔽荫下,下层木人工更新的适宜时间,为今后的生产提供了可靠依据。By analyzing the artificial secondary forest larch stem analysis woods, the growth equations of the upper stand of secondary forest stand were fitted in this paper, and their growing processes were also analyzed. Accordingly, the suitable regeneration time of the under-layer stand was suggested and this will be helps to the yield of forestry native in a certain.
