摘要
在 2 0 0 0年夏季莱州湾加密大面调查资料的基础上 ,研究了莱州湾海域海水的温度、盐度、溶解氧、浊度、叶绿素、无机氮、磷酸盐和硅酸盐的分布特征 ,初步讨论了它们之间的相互关系。结果表明 ,莱州湾盐度值与以前相比有显著升高 ;叶绿素南部的高值区对应于溶解氧的低值区 ,温度的高值区 ;浊度受黄河径流的影响较大 ;无机氮西部浓度高 ,东部浓度低 ,且相差很大 ;浮游植物生长的限制因素东部与西部海域不同 ,东部为氮限制 ,而西部为磷限制。
Based on the investigation data in Laizhou Bay in the summertime of 2000, the distribution features of temperature, salinity, dissolved oxygen, turbidity, chlorophyll, inorganic nitrogen, phosphate and silicate in the sea water are expounded. Also discussed is their relationship between each other. The results show that the salinity in Laizhou Bay has increased remarkably compared with the previous observational data. The high value zone of chlorophyll in the south of Laizhou Bay corresponds with the low value zone of dissolved oxygen and the thermal zone. The distribution of turbidity is mainly governed by the run-off of the Yellow River. It is also found that the inorganic nitrogen concentration is high in the west of Laizhou Bay and low in the east, and the discrepancy is very great. The limiting factor of phytoplankton growing in the east of Laizhou Bay is different from that in the west:the former being nitrogenwhereas the latter being phosphor.
