Research advances in carbon balance in subtropical hilly red soil
亚热带山区红壤地碳平衡研究进展

Carbon balance is becoming a hotspot in global change and geo-science studies. The subtropical hilly red soil area in China is an important production base of foodstuffs and tropical and subtropical economical crops and woods, and also, is very important in carbon balance research because of its special ecological and geographic characters. This paper discussed the significance of subtropical hilly red soil in carbon balance, and reviewed the related research advances and main results, including plant, litterfall, soil carbon storage, and soil respiration etc. The integrative research methods of carbon balance were summarized, and some issues and development directions in carbon balance research were discussed.
