| 摘 要： | 岩溶地区碳循环具有地表与地下双层结构的相互渗透、有机与无机碳循环的相耦合以及生物与非生物过程的相关联等特征,相对于其他陆地生态系统更为特殊和复杂。中国西南地区是全球最大范围的喀斯特连续出露地区,前期研究结果表明该区域的碳循环路径与过程是基本清晰的,但岩石-土壤-植被-大气-水不同界面间的碳通量及迁移转化机制仍然不明确,亟待开展小流域尺度碳循环各个分量的精细观测,以及区域尺度的碳循环遥感估算和模型模拟工作。论文对西南岩溶地区碳循环观测与模拟研究的进展进行了梳理,在此基础上展望下一步需要重点开展的工作,该研究可以为评估全球气候变化对该地区影响及制定适应对策提供参考。 |

| Abstract: | Carbon cycle in karst regions is characterized by a double-layer structure of surface and underground spaces, organic-inorganic coupling, and biological and abiotic process interactions. It is more unique and complex relative to other terrestrial ecosystems. Southwest China is the biggest region of continuous karst landform in the world. The paths and processes of carbon cycle in this region are basically clear based on former research results. However, the carbon flux and transformation mechanisms of the rock, soil, vegetation, atmosphere, and water interfaces are still unclear. It is urgent to perform precision observation of the different components on the scale of small watershed and remote sensing estimation and model simulation on the regional scale. The research progress on observations and simulations of the carbon cycle in Southwest China were summarized in details in this study, and future research emphases were proposed. |
