全球变化与人类活动的相互作用——我国下阶段全球变化研究工作的重点

GLOBAL CHANGE AND HUMAN ACTIVITIES: PRIORITIES OF THE GLOBAL CHANGE RESEARCH IN NEXT PHASE IN CHINA

全球环境变化与可持续发展是当今人类社会面临的两大重要挑战。IGBPⅡ在探索地球系统变化规律的同时,力图将全球变化与可持续发展更紧密地结合,为人类社会的可持续发展提供科学背景和依据。根据国际全球变化研究发展的动向与我国的具体情况,今后我国全球变化与人类活动相互作用研究的重点应放在那些兼备显著区域特色和国际影响力的重大科学问题上。其中值得着重解决的10个科学问题包括:水循环与水问题、人类活动与区域碳循环过程、季风亚洲的人类活动与气候集成、土地利用/土地覆盖变化与陆地生态系统变化、人类活动与大气气溶胶、边缘海及海陆过渡带与人类活动、全球变化的影响与适应性、过去环境变化与中华文明、建设全面小康社会与温室气体减排国际谈判的科学支持、全球变化与人类活动相互作用研究基础信息平台建设。

Global environmental change and sustainable development are both critical challenges human beings are facing. Aiming at the further development of the Earth System science, the new IGBP is trying to combine the two issues as well, by providing scientific basis to the sustainable development. According to the international trend and the situation in China, the global change researches of China in next phase should focus on the key scientific issues with both international significance and regional distinction, such as water cycle and water issues, human activities and regional carbon cycle process, Monsoon Asia under human activities and climate change, land use/cover change and terrestrial ecosystem change, human activity and aerosol, marginal seas/ costal zone and human activity, impacts of global changes and human adaptation, past global changes and the Chinese Civilization, scientific support for the construction of all-round well-off society and the international negotiation on reduction of green house gas emission, and the basic information platform for the research on the interaction of global changes and human activities.
