陆地生态系统与全球变化的联网观测研究进展

Advances in Integrative Studies on Terrestrial Ecosystem and Global Change through Combining Various Observing Systems and Networks

全球变化引起的环境问题已成为国际社会及其科技界共同关注的重大挑战。陆地生态系统的联网观测作为研究全球变化与陆地生态系统相互关系的一种有效手段,越来越受到人们的重视,并且得到了广泛的应用。本文讨论了陆地生态系统联网观测在全球变化科学研究中的作用和地位,并简要介绍了几个有影响的国际陆地生态系统联网观测计划。在此基础上,分析评述了中国陆地生态系统联网观测研究的主要进展以及在全球变化研究中做出的主要贡献,并结合我国科学技术和社会经济发展的需求,指出了近期中国陆地生态系统联网观测研究应该重点发展的领域。

Environmental regime resulted from global change has become a big challenge that is commonly concerned by international society including scientists and technicians. Combination of various observing systems, as an effective and complex method package, has been widely recognized and applied in expounding the interrelations of global changes and terrestrial ecosystems. The paper addressed the importance of combining various observing systems in global change studies and made a brief introduction to several influential systems or networks of glob al terrestrial ecosystem observation. On the basis above, the main contributions to global change studies and the development of Chinese networks and systems for global terrestrial ecosystem observation have been evaluated. On the necessary for development in science and technology and social economy of China, the paper tentatively proposed the prior research fields in terrestrial ecosystems through combining observation systems and networks.
