摘　　要：本文研究了中国第八次南极科学考察青岛至南极航渡中所观测到的大气与海水二氧化碳分压资料，结果表明：７°Ｎ以北、０°至２°Ｓ、１０°Ｓ至４３°Ｓ之间及５８°Ｓ以南的海域是大气二氧化碳的汇区，其间碳通量平均约为６．１ｍｇ／（ｍ２ｈ）；７°Ｎ至０°、２°Ｓ至１０°Ｓ及４３°Ｓ至５８°Ｓ则为大气二氧化碳的源区，其间碳通量约为４．０ｍｇ／（ｍ２ｈ）。In the present work the CO 2 differences between P CO 2 in the surface water and p CO 2 in the atmosphere were determined on the route frome Qindao to Antarctica during Eighth Chinese Antarctic Research Expedition in 1991 . The result of survey indicate: the sea area in north of 7°N , between the equator and 2°S, between 10°S and 43°S, in south of 58° S, serves as a sink for atmospheric CO 2 ,the mean CO 2 fluxes from atmosphere into sea water was about 6.1mg/(m 2·h); the sea area between 7°N and the equator, between 2°S and 10°S, between 43°S and 58°S acts as CO 2 sources, the mean CO 2 fluxes from sea water into atmosphere was about 4.0mg/(m 2·h).
