摘要:
从1990年以来,在国家海洋局第三海洋研究所的临海陆基水池中,应用围隔生态系实验技术对赤潮成因作了几次探索性的研究。针对4次人为引发赤潮的中尺度围隔实验的部分结果,结合已报道的厦门西海域赤潮过程,分析几个主要理化因子(水体稳定性、无机氮、无机磷、可溶性锰、可溶性铁和维生素B12)与硅藻赤潮发生及其规模的关系。

Abstract:
This paper reports the results from a series of Marine Enclosed Ecosystem. Experiments on the mechanism of red tide occurrence have conducted in the land-based tank at the Third Institute of Oceanography, SOA, since 1990.

Some results of artificially induced red tide in 4 mesocosm experiments, reported natural red tide processes in Western Xiamen Harbour, the relationship between the occurrence and distribution scale of diatom red tide, and relevant physical and chemical factors, are analysised and discussed in this paper. Present some results are summarized below.

There was little influences on diatom red tide occurrence by stirring the water column. Close relationship existed between nutrient concentrations and red tide formation in especially the concentration of active phosphates, which might be a inducing and controlling factor for diatom bloom in Western Xiamen Harbour. The (3 - 4) μg/L dissolved Mn, in the water was enough to support the phytoplanktonic proliferation. The unusual increase of dissolved Fe concentration in this region might stimulate the occurrence of diatom red tide. Vitamin B12 can promote the division rate of some diatom, and so induce red tide occurrence or enlarging the distribution scale.

Key words:  Red tide, Enclosed ecosystem, Western Xiamen Harbour, Dissolved, Fe, Active phosphate
