摘要
1987年3月至1988年12月笔者在九龙江口、厦门西海域开展磷等营养要素的生物地球化学研究。本文着重讨论该海域水体中氮磷比值的区域分布和季节变化及其与初级生产力的关系,以及无机氮对磷的地球化学循环的影响。
Based on the survey data of inorganic nitrogen and some species of phosphorus and other parameters from Jiulongjiang estuary and Western Xiamen Harbour from March 1987 to December 1988,the changes of the ratio of nitrogen to phosphorus is discussed in relation to primary productivity in the survey region. Nitrate and ammonium in the region had an influence on the geochemistry of phosphorus. N/P ratio was high with mean 36-64 except in Spring and part of the estuary. Phosphorus, not nitrogen, was the limiting factor to phytoplanktonic growth. Higher nitrate content in the bottom layer hindered the release of phosphorus from surface sediment.
