| 摘 要： | 通过对20年生华北落叶松人工林进行不同强度的间伐试验,结果表明：间伐3 a后与对照相比,不同间伐强度对保留木胸径和树高的影响均显著,其中强度间伐表现最明显,3 a胸径和树高的生长量分别为1.79 cm,2.29 m;中度间伐对林分的蓄积生长量影响最大,初次采用中度间伐可以显著提高林分蓄积量,有效地提高华北落叶松造林的生态效益。

| Abstract: | Different intensity tending experiments of 20 a Larix principis-rupprechatii were conducted with various management.The results showed that the tree height and diameter of those reserved with moderate thinning were higher（1.79 cm and 2.29 m） than the other treatments.Meanwhile,moderate thinning could maintain the maximum accumulation of effective growth.The ecological benefit of larch north could be improved by lowering the density through moderate thinning. |
