【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。更多还原

【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 infecting 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 phytoplankton growth in Bohai Bay in recent years.更多还原
