前言 由于大气二氧化碳（CO_2）逐年增加,已影响到近年来全世界的气候变化,从而越来越受到世界科学界和各国政府的重视。CO_2的增加是由全球工业迅速发展,CO_2气体不断大量排放到地球大气中所致。从工业化前的大约280（ppm）,增长到1988年的350（ppm）这是指大洋上CO_2的变化。陆地和城市大气CO_2的浓度最高可达380（ppm）左右。预计2050年CO_2浓度将是工业化前的2倍多,因此将大大改变地球的气候。 海洋是一个大的CO_2贮存库,对于调节大的时间尺度（一年至许多年）大气CO_2的浓
Introduction As the atmospheric carbon dioxide (CO 2) has been increasing year by year, it has affected the world’s climate change in recent years and has gained more and more attention from the world’s scientific community and governments. The increase of CO 2 is caused by the rapid development of global industry and the continuous discharge of CO 2 gas into the Earth’s atmosphere. From about 280 (ppm) before industrialization to 350 (ppm) in 1988 This refers to the change in CO 2 over the oceans. CO 2 concentrations in land and in the urban atmosphere can reach up to about 380 ppm. It is estimated that the CO 2 concentration in 2050 will be more than twice that of pre-industrialization and will therefore greatly change the Earth’s climate. The ocean is a large CO 2 reservoir, and for the regulation of atmospheric CO 2 concentrations over large time scales (year to many years)
