摘要
分别于2008年2月(冬季),5月(春季),8月(夏季)和11月(秋季)对深圳湾海水中COD与TOC进行了四个航次的调查和研究,结合国家标准方法,获得了深圳湾COD与TOC的平面和季节分布特征,并对COD与TOC的相关性进行了探讨。结果表明:整个深圳湾海域COD基本遵循从湾内到湾外,逐渐降低的平面分布规律以及夏季>春季>冬季>秋季的季节分布特征;海水TOC也基本遵循从湾内到湾外,逐渐降低的平面分布规律以及秋季>冬季>夏季>春季的季节分布特征;深圳湾COD与TOC之间有着良好的相关性,相关系数大于0.9。
The survey on chemical oxygen demand （COD） and total organic carbon（ TOC ） in Shenzhen Bay was separately carried out in Feb. （Winter）, May （Spring）, Aug. （Summer） and Nov. （Autumn） 2008. The plane and seasonal distribution characteristic of COD and TOC in Shenzhen Bay was acquired, combining the national standard methods. The correlation was analyzed between COD and TOC. The results showed that COD was decreased gradually form inside to outside of the Bay. The average contention of COD has a trend of summer 〉 spring 〉 winter 〉 autumn. TOC was also decreased gradually form inside to outside in the Bay. The average contention of TOC has a trend of autumn 〉 winter 〉 summer 〉 spring; There was a good linear correlation between COD and TOC, and the correlation coefficient was over 0.9.
