摘　　要：研究了抚育间伐对30a生油松人工林的影响,以林木分级为基础,以弱度、中度、强度和对照4种间伐强度对油松林进行间伐试验。结果表明:不同间伐强度处理对其生长以及碳储量的影响存在显著差异,其中中度间伐有益于油松林分生长和碳储量提高,该研究为人工林抚育间伐提供了科学依据。The effect of thinning on Pinus tabulaeformis plantation which had been growing 30 years were studied.Based on the tree class,the experiment on which thinning intensity of Pinus tabulaeformis where weak,moderate,intensive and CK were made.The results indicated that different thinning intensity of Pinus tabulaeformis plantation were different for tree biomass amount and carbon storage.Moderate thinning intensity could evidently advance tree biomass amount and carbon storage.This research will provide the basis for thinning of plantation.
