摘要
本文报道了1987年夏、冬两个航次在26°50′～32°30′N,124°30′～131°30′E海区中可溶性无机磷酸盐的调查结果,阐明了磷的分布特征和形成机制。结果表明陆架区表层测值较高,大洋区为低值区,底层则相反。大洋水常年分层,中层水有爬坡涌升现象,其浓度与Aou呈正相关,与pH和S呈负相关。夏、冬两季底层磷与Aou呈正相关,其浓度变化主要依赖于生物过程。
This paper reports the results of the investigation of soluble inorganic phosphate obtained during two cruises in the area (26°50'～32°30'N, 124°30'～131°30'E) in the summer and winter of 1987, and expounds the distribution characteristics and formation mechanism of phosphate. The results indicate that: The phosphate concentration is high in the surface of the shelf water and low in the oceanic water. But the contrary is true in the case of the bottom layer. In the oceanic area, seawater is always stratified and in the intermediale water, there is upwelling. The concentration correlates positively to AOU and negatively to pH value and salinity. In two seansons, the changes of the bottom phosphate concentralion mainly depend on the biological processes and correlate positively to AOU.
