摘要
通过对2003—2007年山东省近岸海域水质监测数据的分析,总结其近岸海域的水质状况及污染特征,并采用秩相关系数法对山东省近岸海域水质状况时空变化趋势进行分析与评价。结果表明,山东省近岸海域水质以一、二类海水为主,黄海近岸海域水质略好于渤海。全省近岸海域污染以有机污染为主,主要污染因子为无机氮和化学需氧量。2003—2007年,山东省近岸海域水质变化趋势基本稳定,但主要污染物化学需氧量的含量呈上升趋势。
Based on costal waters quality monitoring data in shandong province from 2003 to 2007, this paper summarizes the water quality status and pullution characteristics. The dynamic varietal trends of the water quality were also evaluated by Spearman correlation method. Results show that the water quality was mainly the first and second grade sea water, and the water quality on Yellow Sea was slightly better than Bohai Sea. In Shandong Province, the dominant contamination was organic pollution, and the pullution factors were mainly inorganic nitrogen and COD. From 2003 to 2007, the trends of water quality of Shandong costal waters were basically stable. However, the trend of the COD appears increasing and statistically significant.
