摘要
据1984年5月至1985年2月的调查资料，计算了该水体中二氧化碳体系各分量的含量，研究了它们与pH、HCO-3／CO32-、Alk、DIN、PO43-－P、Chl－a、DO、S、t等环境因子的相关性。结果表明PCO2；、CO2（T）、HCO3-、CO32-与pH、HCO3-／CO32-呈极显著的线性相关；HCO3-、CO32-、CO2与Alk也呈非常显著的线性相关；即使将它们四季表、底层的全部数据（n＝310）合在一块统计，其相关系数仍均在α＝0．001水平上显著。秋、冬季CO2（T）、HCO32-、CO32-与DIN、PO43-－P、S、t呈显著的线性相关，春、夏季的相关性较差。受生物活动影响，表层CO2（T）与Chla和DO呈较显著的相关，底层的相关性较差。
Relationships between various components of the seawater CO2 systenl and hydrologi cal, chemical and biological factors are described, on the basis of calculation results from May, 1984 to February, 1985 western Taiwan Strait, There exist definite relationship be tween the components and pH, Alk, HCO3- /CO32- ratio in various seasons. CO2, (T), HCO3-,CO32- are closely related to DIN. PO43- -P, salinity, temperature in autumn and winter, and relatively poor in spring and summer. CO2 (T) on the surface layer has a distinct relation with chlorophyll-a and DO, but insignificant except summer on the bottom. All the relation ship showed that the variation of the content of the components are closely related to the en vironment factors.
