北方森林的生态恢复力是衡量从干扰中恢复的森林生态系统能力的一个重要因素，并且对大尺度因素（例如，气候变化、火灾干扰和人类相关影响）。因此，量化这些因素的影响对森林生态系统管理越来越重要。在这项研究中，我们调查了气候变化的影响，气候引起的火灾制度，森林经营方案对森林生态恢复力的森林景观模型在大兴安岭，中国东北的北方森林。首先，利用LANDIS PRO模型模拟了3个研究变量对森林地上生物量、生长空间占有量、年龄组结构和中晚生种比例等指标的影响。其次，我们根据这四个选定的指标计算了生态恢复力。我们设计了五种模拟情景：当前火灾情景、火灾发生率增加情景、气候变化情景、气候引发火灾情景和气候火灾管理情景。我们分析了从2000年到2300年的五种情景下的生态恢复力。结果表明，2000年的林分密度和断面积初始值能够较好地反映当年的真实的森林景观，2010年的模拟景观与当年的森林资源清查数据在景观尺度上没有显著差异。模拟的火干扰结果与火烧区的实地清查数据一致。与当前火灾情景相比，火灾发生率增加30%的森林在景观尺度上的生态恢复力增加了12.4-43.2%，而火灾发生率增加200%的森林在所有模拟时段内的生态恢复力将下降2.5-34.3%。在低气候诱导火灾情景下，生态恢复力在所有模拟时期都比参考情景高12.3-26.7%。与参考情景相比，在高气候引发的火灾情景下，景观尺度的生态恢复力在短期和中期分别显著下降了30.3%和53.1%，而在长期内略有增加3.8%。在景观尺度上，与无森林管理情景相比，在低气候引发的火灾情景下，所有采伐和种植策略下的生态恢复力均下降了5.8-32.4%，而在高气候引发的火灾情景下，只有中等和高种植强度情景下的生态恢复力明显增加（1.7-15.8%）。我们的研究结果为未来的森林管理提供了见解，并对提高北方森林的可持续性产生了影响。
The ecological resilience of boreal forests is an important element of measuring forest ecosystem capacity recovered from a disturbance, and is sensitive to broad-scale factors (e.g., climate change, fire disturbance and human related impacts). Therefore, quantifying the effects of these factors is increasingly important for forest ecosystem management. In this study, we investigated the impacts of climate change, climate-induced fire regimes, and forest management schemes on forest ecological resilience using a forest landscape model in the boreal forests of the Great Xing’an Mountains, Northeastern China. First, we simulated the effects of the three studied variables on forest aboveground biomass, growing space occupied, age cohort structure, and the proportion of mid and late-seral species indicators by using the LANDIS PRO model. Second, we calculated ecological resilience based on these four selected indicators. We designed five simulated scenarios: Current fire only scenario, increased fire occurrence only scenario, climate change only scenario, climate-induced fire regime scenario, and climate-fire-management scenario. We analyzed ecological resilience over the five scenarios from 2000 to 2300. The results indicated that the initialized stand density and basal area information from the year 2000 adequately represented the real forest landscape of that year, and no significant difference was found between the simulated landscape of year 2010 and the forest inventory data of that year at the landscape scale. The simulated fire disturbance results were consistent with field inventory data in burned areas. Compared to the current fire regime scenario, forests where fire occurrence increased by 30% had an increase in ecological resilience of 12.4–43.2% at the landscape scale, whereas increasing fire occurrence by 200% would decrease the ecological resilience by 2.5–34.3% in all simulated periods. Under the low climate-induced fire regime scenario, the ecological resilience was 12.3–26.7% higher than that in the reference scenario across all simulated periods. Under the high climate-induced fire regime scenario, the ecological resilience decreased significantly by 30.3% and 53.1% in the short- and medium-terms at landscape scale, while increasing slightly by 3.8% in the long-term period compared to the reference scenario. Compared to no forest management scenario, ecological resilience was decreased by 5.8–32.4% under all harvesting and planting strategies for the low climate-induced fire regime scenario, and only the medium and high planting intensity scenarios visibly increased the ecological resilience (1.7–15.8%) under the high climate-induced fire regime scenario at the landscape scale. Results from our research provided insight into the future forest management and have implications for improving boreal forest sustainability.
