气候变化下的森林管理需要评估气候变暖和干扰对树种组成、年龄结构和空间格局的影响。我们使用析因实验设计和模拟模型研究了这些对中国东北部北方森林的影响。我们使用空间明确的森林景观模型（LANDIS）来评估三个自变量的影响：气候（当前和预期的未来）、火灾状况（当前和增加的火灾）和木材采伐（没有采伐和合法采伐）。模拟表明，这种森林景观将在气候变化的情况下受到重大影响。气候变暖将显着增加大多数树木的数量，尤其是阔叶树种（白杨、杨树和柳树）。然而，气候变暖对针叶树丰度、林龄结构多样性和空间景观结构变化的影响小于焚烧和采伐。燃烧是除落叶松外的针叶树丰度和中期乔木丰度的主要影响因素。采伐对落叶松和桦树丰度以及建树期（1-40 年）、早期（41-80 年）和老年阶段（>180 年）树木丰度的影响最大。木材采伐和燃烧造成的干扰可能会增加森林破碎化和减少森林多样性，从而显着改变森林生态系统动态。模拟结果提供了对北方森林长期管理的深入了解。
Forest management under a changing climate requires assessing the effects of climate warming and disturbance on the composition, age structure, and spatial patterns of tree species. We investigated these effects on a boreal forest in northeastern China using a factorial experimental design and simulation modeling. We used a spatially explicit forest landscape model (LANDIS) to evaluate the effects of three independent variables: climate (current and expected future), fire regime (current and increased fire), and timber harvesting (no harvest and legal harvest). Simulations indicate that this forested landscape would be significantly impacted under a changing climate. Climate warming would significantly increase the abundance of most trees, especially broadleaf species (aspen, poplar, and willow). However, climate warming would have less impact on the abundance of conifers, diversity of forest age structure, and variation in spatial landscape structure than burning and harvesting. Burning was the predominant influence in the abundance of conifers except larch and the abundance of trees in mid-stage. Harvesting impacts were greatest for the abundance of larch and birch, and the abundance of trees during establishment stage (1–40 years), early stage (41–80 years) and old- growth stage (>180 years). Disturbance by timber harvesting and burning may significantly alter forest ecosystem dynamics by increasing forest fragmentation and decreasing forest diversity. Results from the simulations provide insight into the long term management of this boreal forest.
