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.
