| 摘 要： | 通过对1995～2005年海水样品的采集、检测及查阅相关文献资料获得渤海湾氮、磷营养盐的数据资料.讨论了渤海湾氮磷比的变化趋势、年际变化的影响因素,以及氮磷比与浮游植物生长限制性因子的关系.研究结果表明,渤海湾95年氮、磷营养盐浓度有异常高值,其中氮为0.389 mg/L.氮磷污染近年来有加重趋势,氮磷比大致呈逐年增加趋势,P成为近年来渤海湾浮游植物生长的限制因子.

| Abstract: | The data of nitrogen and hosphorus nutrient salts was obtained by collecting the seawater specimens in in Bohai Bay in 1995 - 2005, detecting and consulting relative literature. The inffecting factors of variation trend and variation between years of N, P and N/P in Bohai Bay, as well as the relationships of N/P and the limitation factors for phytoplankton growth were discussed. The concentration of N and P was specially higher in 1995, in which, N contentration was 0.389 mg/L. The pollution of N and P has being heavier in recent years and the rate of N and P increases year by year. P has been the limitation factor of ohvtoolankton growth in Bohai Bav in recent vears. |
