Abstract:

The global carbon cycling is one of the core projects of global biogeochemistry. It is concentrated on themissing sink. Because of the complexity of carbon cycles in ecosystems and the limitation of methodology,there aremany difficulties with confirming the existence of missing sink,or determining the location or causes of missingsink. Recently,it has been found that the most part of missing sink lies in the carbon-fixing by boreal terrestrialforest,the absorption by ocean,and the carbon sink in carbonate rock area,as well as the transportation of carbonpool from terrestrial ecosystem to oceans. The approaches for future research on missing sink are integration of thegeographic information techniques and field measurement,with the aid of modeling.

Key words: carbon cycle, missing sink, forest ecosystem, ocean, lithosphere
