摘要
通过对烟台海洋管区1988～1996年9年的监测资料分析,发现烟台近岸海域无机磷含量的变化规律为:1989～1993年基本在一类标准线附近变动,从1993年开始无机磷的含量呈快速上升趋势,至1996年无机磷的含量超过了二类水质标准,为三类水质.并针对海域内无机磷上升的原因进行了分析,结果表明:烟台近岸海域磷的入海通量年增长率为16.5％,其中含磷洗衣粉及磷肥的使用量的年增长率分别为12.9％、17.5％,且它们与入海通量之间有比较好的正相关关系。另外,海区内磷的迁移与再生机制也导致无机磷在烟台近海的积累。
The detailed analysis of the monitoring data for the Yantai sea area from 1989~1996 shows that the fluctuation regularity of inorganic phosphorus is as follows:From 1989~1993.it fluctuates near the first -lass standard line on the whole;from 1993, on the content of inorganic phosphorus shows an upward tendency;by 1996, the content had exceeded the second-lass water quality standard. Furthermore, the analysis of the reasons for the increase of inorganic phosphorus in the nearshore waters of Yantai shows that the phosphorus flux into the sea increases by 16. 5% per year,in which the increase rates of the phosphorus contained in washing powder and in phosphate fertilizer are 12. 9% and 17. 5% per year respectively. And there is a better positive interrelation between them and the flux into the sea. In addition,the movement of phosphorus and the regeneration mechanism also lead to the accumulation of inorganic phosphorus in the nearshore waters of Yantai.
