Large-scale terrestrial ecosystem science research becomes an important research field with the promotion of meeting the scientific demand of biodiversity conservation, global climate change mitigation, regional eco-environment governance, and social sustainable development. It is developing rapidly under the guidance of China's ecological civilization construction strategy. Here, we systematically discussed the missions, theoretical foundation and methodology of large-scale terrestrial ecosystem science research and proposed a new theoretical foundation, conceptual system and logical framework for macroecosystem science research on the basis of macrosystem ecology theory. It elaborated the discipline connotation and application of the macroecosystem science to 1) deve-lop the conceptual network of ecosystem science based on the systematic characteristics of ecosystems; 2) develop the theoretical system of ecosystem state change analysis based on the ecosystem integrity and emergence characteristics; 3) develop the theoretical system of integrated research for ecosystem structure-process-function-service cascade relationship based on the attributes and state of ecosystems. We also discussed the methodology and technical system of regional and continental macroecosystem science research, and highlighted the urgency to construct a new generation of continental ecosystem observation and research network, and to develop the network observation-network experiment-numerical simulation-knowledge fusion four-in-one infrastructures.
大规模陆地生态系统科学研究在满足生物多样性保护、全球气候变化缓解、区域生态环境治理和社会可持续发展等科学需求的推动下，成为一个重要的研究领域。在中国生态文明建设战略的指导下，该领域发展迅速。本研究系统地讨论了大规模陆地生态系统科学研究的任务、理论基础和方法学，并在宏观系统生态学理论的基础上，为宏观生态系统科学研究提出了一个新的理论基础、概念体系和逻辑框架。阐述了宏观生态系统科学的学科内涵和应用，包括：1）基于生态系统的系统特征，发展基于生态系统科学的概念网络；2）基于生态系统完整性和涌现性特征，发展生态系统状态变化分析的理论体系；3）基于生态系统的属性和状态，发展生态系统结构-过程-功能-服务级联关系的综合研究理论体系。本研究还讨论了区域和大陆宏观生态系统科学研究的方法学和技术体系，并强调了构建新一代大陆生态系统观测和研究网络以及发展观测网络-实验-数值模拟-知识融合四位一体基础设施的紧迫性。
