全球变化与陆地生态系统研究：回顾与展望

全球变化与陆地生态系统相互关系的研究是国际地圈－生物圈计划（IGBP）的核心研究计划之一，也是整个全球变化的研究核心领域之一。该计划自上世纪八十年代启动以来，已经取得了一系列重要的研究成果，对于推动全球变化研究发挥了重要作用。中国学者在全球变化与陆地生态系统研究领域也开展了许多工作并取得了重要成绩。按照我国科学技术和社会经济发展的需求，本文提出了未来我国在该领域的研究重点，包括（1）中国陆地生态系统重要生命元素的代谢及其耦合机制研究；（2）全球变化敏感区域或重要样带上陆地生态系统对全球变化的影响研究；（3）我国的C、N、P、S生物地球化学循环与全球变化的关系研究；（4）发展中国特色的区域植被动态模型。

STUDY ON GLOBAL CHANGE AND TERRESTRIAL ECOSYSTEMS:HISTORY AND PROSPECT

As one of the core projects of IGBP and the global change study, GCTE-Global Change and Terrestrial Ecosystems is a hot research topic for the global ecological community. Since its inception in 1980s, a series of important results have been achieved by the scientists, including Chinese scientists in this area, which significantly advances the study on global change in the world. To meet the needs for scientific, technological and socio-economic development in China, we proposed four areas on which the Chinese scientists should focus their study of global change and terrestrial ecosystems in future, including: (1) Metabolism and coupling mechanism of key life elements in terrestrial ecosystems in China; (2) Implications of terrestrial ecosystems in areas sensitive to global change and in important transects on global change; (3) Interactions between biogeochemical cycle of C, N, P, S in China and global change; and (4) Development of regional dynamic vegetation model which meets the actual needs of China.
