东亚地区碳循环研究新进展

近百年来,温室效应的日益加剧,引发了全球温暖化、海平面上升等一系列重大环境问题,碳循环研究因此而受到全球范围的普遍关注和重视.东亚地区因其独特的气候特征,多样化的物种和生态系统,以及活跃的人类活动而成为世界碳循环研究中不可或缺的一部分.在中、日、韩三国联合启动东亚碳循环前沿研究计划(A3 Foresight Program)三周年之际,《中国科学生命科学》(Science China Life Sciences)2010年第7期发表了东亚地区碳循环研究专题,包括14篇述评和研究论文,从区域碳储量及其变化特征,不同地带森林生态系统的碳源汇变化,草地和农田生态系统的碳储量和碳循环研究中的新方法等多个方面系统展示了东亚地区碳循环研究的最新进展.

The Recent Progress of Carbon Cycle Research in East Asian

Alongside the increasing of CO2 released, greenhouse effect on earth became more and more serious over the past century, finally resulted in global warming and sea level rise. To solve the environment problems came from greenhouse effect, scientists around the world carried out many research projects on the globle carbon cycle. Compared with other continents such as Europe and America, East Asia may have more ecological importance in the study of global carbon cycle. In 2007, an international joint research project (the A3 Foresight Program), aiming to investigate the carbon sources and sinks in East Asia, was launched, which is founded by the national foundations of China, Japan and South Korea. To reflect the main outcomes in the past three years from this program, the journal Science China Life Science published a special issue "Carbon Budget in East Asian Ecosystem" in 2010 (Vol. 53, No. 7, 2010). This issue contains 14 contributions categorized into 4 parts, including carbon stocks and their regional variations, changes in carbon sources and sinks for different forest ecosystems, carbon stocks and changes in grassland and farmland ecosystems, and new approaches to carbon cycle research. The main points and significations of these articles are comprehensively commentated.
