大亚湾水体中溶解的碳水化合物

根据1985年10月至1986年8月对大亚湾进行的环境调查,本文报道海水中溶解的碳水化合物(DCHO)的调查结果,讨论了该海区DCHO的分布特征及季节性变化。对DCHO和叶绿素a、磷酸盐、溶解氧、颗粒有机碳、温度以及盐度之间进行了相关分析,综合探讨了影响D-CHO含量变化的因素。结果表明,浮游植物在大亚湾水体中DCHO的浓度调节方面起着主要的作用。

DISSOLVED CARBOHYDRATE IN DAYA BAY WATERS

Baseb on an environmental survey made in the northeast coast of South China Sea at Daya Bay, from October 1985 to August 1986, this article reports the survey results of dissolved carbohydrate (DCHO) in sea water, and discusses the distribution characters and season variation of DCHO in this estuarine. The content of DCHO in water is 0.16-2.34 mg/L.Correlation analyses between DCHO and chlorophyll-a, phosphate, dissolved oxygen, particulate organic carbon, temperature, and salinity were carried out. The influencing factors which change the concentration of DCHO were studied comprehensively. Obtained results suggest that phytoplankton play a major role in the regulation of concentration of DCHO in Daya Bay waters.
