Carbon cycle in agricultural ecosystem

Study of terrestrial ecosystem carbon cycle is most closely related to human production and life, and study of agricultural ecosystem carbon cycle is the most important part. With the efforts of researchers in China and abroad, there are a large numbers of achievements about carbon source/sink benefit in agricultural ecosystem, the process of carbon cycling, simulation modeling and response of agricultural ecosystem to global warming. This paper mainly discussed the carbon source/sink function of agricultural ecosystem, and emphasis on generalizing the influence factors of agricultural ecosystem cycle and several methods for the model. Besides, existing problems in related researches were discussed and future research direction of this field was also put forward.
