Studies on carbon budget scored remarkable progress

Dec 07, 2006

 

On Nov. 23, , a key CAS research project on carbon budget passed the review by a panel of experts under the auspices of the CAS Bureau of Integrated Planning and the CAS Bureau of Science and Technology for Resources and Environment. The panel was made up of 11 prestigious experts, led by Prof. CHEN Yiyu, a CAS Member and President of National Natural Sciences Foundation of China.

Entitled Carbon Budget in Terrestrial and Marginal Sea Ecosystems in China, the project was jointly led by the CAS Institute of Geographic Sciences and Natural Resources Research, and the CAS Institute of Atmospheric Physics. About 400 researchers from 18 CAS institutions and some field stations under the Chinese Ecosystem Research Network (CERN) have been engaged in the project since Sept. 2001. To date, some outstanding results have been made, including the following:

The inauguration of the ChinaFLUX (www.chinaflux.org.cn), a data and information management system on carbon cycling in China, as well as the model and integrated modeling system on carbon cycling in terrestrial and marginal sea ecosystems in China; research into the impact of key climatic and biological factors and human activities on ecosystem carbon cycling process; initially identification of the spatial-temporal pattern of carbon sink and source in the terrestrial and marginal sea ecosystems in China and its response to climate change; Preliminary assessment of the potential of increased carbon sink in the terrestrial ecosystems in China under various technical practices; and publication of more than 800 scientific papers (245 in SCI and EI journals), filing for 23 patents, and the training of 274 post graduate students.

The project has also greatly advanced the carbon flux measurement and research in this country, which not only made it possible to carry out in-depth analysis on the matter cycle in terrestrial ecosystems and response to regional climate, but provided a solid basis to estimate the carbon budget at the national level. The research findings are valuable for the policy-makers to understand the function of ecosystems as carbon sink in China, develop strategies on carbon management and negotiations of UN Framework Convention on Climate Change.

The carbon budget balance at the national level is a critical issue in international negotiations on carbon emission, says CAS Vice President Li Jiayang, expressing hopes that the team will contribute more to providing better information service to the national policy-makers by generating more important research results.
