【摘要】 随着人类开发利用海洋的活动增多,海洋生态环境压力日益严重。根据江苏近岸海域16个监测点的数据,分析了反映水域质量的环境因子,并与国家标准进行比较,结果表明:溶解氧、化学需氧量、石油类、重金属满足第一、二类海水水质标准要求;超出标准的环境因子是营养盐成分,包括无机氮、磷酸盐。江苏近岸海域从北向南在空间上也表现出一定的差异性,连云港近岸海域污染要素表现为重金属和石油类,盐城和南通近岸海域污染要素主要为营养盐类。更多还原

【Abstract】 In recent years,with the increase of human activities in exploiting and utilizing the oceans,the pressure of marine ecological environment is becoming more and more serious. According to the data of 16 monitoring points at Jiangsu coastal,and the environmental factors that reflect water quality are analyzed,further compare with national standards. The result showed that concentration of dissolved oxygen,chemical oxygen demand,petroleum and heavy metals were lower and within the first-second-class water quality standards. And concentration of nutritive salt including inorganic nitrogen and phosphate were higher and exceed national standard. There are some differences in the space from north to south along Jiangsu coastal area. The pollutants were heavy metals and petroleum in Lianyungang costal. Nutritive salt was dominant in Yancheng and Nantong.更多还原
