摘要 综述了大气CO2浓度升高对根系、根际、根系分泌物、土壤呼吸和土壤物质转化和C、N循环影响的研究进展,阐述了有关实验的研究情况,以及它们在整个生态系统响应大气CO2浓度升高中的重要作用、目前研究中存在的争论、以及还需要研究的领域和方向及其研究的重要性。 Advances in the effect of elevated CO2 on roots, rhizosphere, root exudates, root respiration and the turnover and cycling of C、N were reviewed. Elaborate the results and others of related research,their importance in the responses of whole ecosystem to elevated atmospheric CO2 concentration, the debates in current research, the fields and directions needed continuing and the importance of these studies.
