| 摘 要： | 1999年4－5月，在现场条件下对天然水体中浮游植物以外加营养盐受控培养的方式，研究和探讨春季渤海中部、莱州湾和渤海海峡3个海区的浮游植物生长的营养盐限制问题。结果表明，在莱州湾附近浮游植物生长受到显著的磷限制；尽管水体中硅酸盐浓度较历史水平大大降低，并且实验进行时硅藻为优势种，但是硅酸盐尚不成为限制因子；渤海中部不存在营养盐的限制问题，营养盐浓度和结构相对适宜；渤海海峡也不存在营养盐的限制问题，但是溶解无机氮的相对含量略低。

| Abstract: | Experimental study on the nutrient limitation to the phytoplankton in the Laizhou Bay,Central Bohai Sea and Bohai Sea Strait was carried out in April and May,1999 by the method of in situ nutrient enrichment experiment. It was evident that phosphorus was the first nutrient to limit the growth of phytoplankton in Laizhou Bay,but silicate limitation was not revealed,although silicate concentration decreased greatly compared with the past observations and diatoms were the dominant species;nutrient concentrations were in a relatively suitable ratio in the Central Bohai Sea;and there was no significant nutrient limitation in Bohai Sea Strait,although the concentration of dissolved inorganic nitrogen was relatively low on occasion. |
