海域面积约7.7万平方公里的东海,港湾及岛屿众多,海洋资源种类繁多。《2016年东海区海洋环境公报》显示,东海海水环境质量总体较好,近岸以外海水基本符合第一类海水水质标准。但近岸局部海域(包括湿地、港湾和河口三类生态系统类型)存在一定程度的污染,无机氮、活性磷酸盐超标较为严重。东海南部的台湾海峡近年来也发生了一些令人担忧的变化,如传统优质鱼类资源量大幅下降等。
The sea area of about 77,000 square kilometers of the East China Sea, harbor and island many, a wide range of marine resources. The “Marine Environment Bulletin of the East China Sea in 2016” shows that the environmental quality of the seawater in the East China Sea is generally good. The seawater beyond the near-shore area basically meets the first-class seawater quality standards. However, some coastal waters (including three types of wetlands, estuaries and estuaries) have some degree of pollution. Inorganic nitrogen and active phosphate exceed the standard seriously. In recent years, some disturbing changes have taken place in the Taiwan Strait to the south of the East China Sea, such as the drastic drop in the quantity of traditional high-quality fish stocks.
