长期定位观测网络是各国科研人员在研究与揭示生态系统结构与功能变化规律时采用的重要方法,是阐明生态系统内在机制、动态平衡以及生物化学循环过程不可替代的研究手段。世界各国都建立了生态资源与环境监测网络,是目前长期定位观测发展的主流方向。文中介绍了美国试验林网络体系(EFRs)的背景与起源、任务目标、网络构架、运行机制、研究内容、贡献与成就,以及在其发展过程中存在的问题;希望通过分析美国试验林网络体系的建设和发展,为我国未来林业生态观测网络建设提供参考。
The long-term observation network is an important method used by researchers in various countries to study and reveal the law of ecosystem structure and function, and is an irreplaceable research method to elucidate the intrinsic mechanism of ecosystem, dynamic balance and biochemical cycle. All countries in the world have set up monitoring networks for ecological resources and environment and are the mainstream of long-term positioning and observation. This paper introduces the background and origin, mission objectives, network structure, operation mechanism, content, contribution and achievements of the American experimental forest network system (EFRs) as well as the problems in the development of the experimental forest network system in the United States. Construction and development of China’s forestry ecological observation network for the future to provide a reference.
