Ecosystem responses to global change are strongly regulated by long-term processes such as soil carbon dynamics, species replacement, shifts in community structure, accrual of nitrogen capital in ecosystems, and primary and secondary succession. Scientists have developed a variety of complementary approaches to address these long-term issues. Each approach has its benefits, challenges, and limitations. This workshop will explore the breadth of existing approaches and activities to addressing this challenge. These approaches include space-for-time studies; studies along natural gradients of temperature and precipitation; and simulation modeling often combined with sophisticated data simulation approaches among others. It is critical to develop coordinated approaches to address long-term issues in global change research. Important topics that must be considered include: 1) key research questions; 2) appropriate research approaches including experiments and the required infrastructure; and 3) data analysis techniques especially suited for the study of long-term phenomena. The workshop participants will review extant long-term research efforts on climate change impacts, brainstorm on key long-term issues, examine effectiveness of long-term experiments, and develop coordinated approaches to investigate long-term processes. This workshop is vital to foster the ongoing scientific discussion and development of any future experimental approaches or designs for addressing the long-term processes associated with global change.

生态系统对全球变化的反应受到长期过程的强烈调控，如土壤碳动态、物种更替、群落结构的变化、生态系统中氮资本的积累以及初级和次级演替。科学家们已经开发出各种互补的方法来解决这些长期问题。每种方法都有其优点、挑战和局限性。这次研讨会将探讨应对这一挑战的现有方法和活动的广度。这些方法包括空间换时间研究；沿着温度和降水的自然梯度进行研究；以及常常与复杂的数据模拟方法相结合的模拟建模等。制定协调一致的方法来解决全球变化研究中的长期问题至关重要。必须考虑的重要议题包括：1)关键研究问题；2)适当的研究方法，包括实验和必要的基础设施；3)特别适合研究长期现象的数据分析技术。研讨会参与者将回顾现有的关于气候变化影响的长期研究工作，就关键的长期问题集思广益，审查长期实验的有效性，并制定协调一致的方法来调查长期过程。这一讲习班对于促进正在进行的科学讨论和发展任何未来处理与全球变化有关的长期进程的实验方法或设计都是至关重要的。
