We assessed the environmental sensitivities of forest ecosystem functions in mountainous forest ecosystems in climate change by using field measurement data and ecosystem modeling simulations. We clarified that ecosystem functions were strongly influenced by changing canopy phenology and snow-cover period under global warming. Our analysis indicates the importance of understanding space-time distributions of canopy phenology dynamics and snow-cover and of their consideration into the mechanistic evaluation of ecosystem functions in the climate studies.

利用野外实测数据和生态系统模型模拟，对气候变化下山地森林生态系统功能的环境敏感性进行了评价。在全球变暖的背景下，林冠物候和积雪期的变化对生态系统功能产生了强烈的影响。我们的分析表明，在气候研究中，了解冠层物候、动态和积雪的时空分布及其对生态系统功能的机制评估的重要性。
