基于FORECAST模型的长白落叶松人工林经营措施对长期生产力的影响
Using an ecosystem simulation model FORECAST to evaluate the effects of forest management strategies on long-term productivity of Korean larch plantations.
摘要
Abstract
The dynamics of biomass, nutrient storage and long-term 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 long- term 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 long-term productivity of larch plantation using different felling cycle.关键词
