2009-2011年渤海湾赤潮监控区营养盐概况分析
Nutrient Conditions of the Red Tide Monitoring Area in the Bohai Bay from 2009 to 2011
摘要
Abstract
On the basis of the monitoring data of nutrients(N,P and Si)in the surface seawater from May to October(2009-2011)in the red tide monitoring area at six monitoring stations of the Bohai Bay,nutrient conditions in the red tide monitor-ing area were analyzed and discussed. The results showed that the water quality in the red tide monitoring area was still seri-ously over-nutritious and polluted with high N and P contents obviously in recent three years and N pollution was more seri-ous than that of P;DIP content had the biggest change in that three years at the six stations. The spatial variation coefficient of DIP was 0.14~0.39,which was higher than inorganic nitrogen and silicate. As for the time distribution,the surface sea-water nutrient contents had significant monthly variation characteristics of first increasing and then decreasing,which reached maximum values in August. As for the nutrient structure characteristics,NO-3 -N accounts for 57% to 70% of the inorganic nitrogen content,which was the main form of inorganic nitrogen. As for the red tide-monitoring area eutrophication classification,the red tide-monitoring area had been transformed from phosphorus limitation in 2009-2010 into the eutrophic state in 2011.关键词
