摘要: 为了对东北地区东部落叶松人工林的多代经营提供指导，以黑龙江省孟家岗林场的长白落叶松人工林为对象，采用森林生态系统经营管理模型FORECAST，从轮伐期长度、林地枯落物的管理和采伐剩余物的处理方面，评价不同经营措施下落叶松人工林的生物量、养分动态和长期生产力。结果表明：常规森林利用方式下维持落叶松人工林长期生产力的轮伐期应大于35 a；落叶松林地枯落物的保留可以显著提高各种轮伐期长度时的林地生产力，短轮伐期时作用效果尤为明显；全面保留采伐剩余物可以维持不同轮伐期条件下落叶松人工用材林的长期生产力。

Abstract: The dynamics of biomass, nutrient storage and longterm productivity of Korean larch plantations growing in Mengjiagang Forest Farm of Heilongjiang Province, northeastern China, following continuing rotation cropping, was studied by employing a ecosystem simulation model (FORECAST, forestry and environmental change assessment) of incorporating rotation length, forest floor litter management and logging slash treatment. The conclusion was the followings: the suitable rotation of sustaining the longterm productivity under the general treatments should be more than 35 years; the soil productivity of larch plantation using different felling cycles could be improved by reserving litter fall, and was especially obvious to the short felling circle; the treatment of keeping all logging slash could sustain longterm productivity of larch plantation using different felling cycle.-
