摘要
通过对钦州湾20a（1983—2003年）来10个航次COD的分析研究，结果发现：该湾COD具有开发初期明显偏低、中期明显偏高、后期略有下降的变化特征；在季节变化上以春夏季高、秋季适中、冬季较低为特点；但在区域分布上却随着季节变化差异较大。这种分布特征的形成。与该湾COD的补充与消减途径随季节变化较大有关。该湾的水体自净条件在其中起重要作用。
According to the study of the change of COD content for 10 voyages in Qinsheu Bay in recent 20 years, the change character of COD content was found in Qinsheu Bay. COD content was obvionsly low during the early developing term, high on the middle term and back a little on the late term. It is high in Spring and Summer, medium in Autumn and low in winier. The changes in the various area differ a lot With the seasons. The form of this character was related with the supplement of COD and the process of digestion and attenuation of COD and seasons. The condition of water serf-clean in the bay played an important role.
