| 为了解铁山港海域的海水水质与底质环境现状,在铁山港海域(109°30'~109°36'E,21°25'30″~21°31'30″N)设点12个。水质采样3次,底质采样1次。水质分析项目有水温、盐度、pH值、溶解氧、化学耗氧量、硝酸盐、亚硝酸盐、活性磷酸盐、油类和悬浮物。底质分析项目有Cu、Pb、Zn、Cd、Hg、硫化物、有机质。结果表明:铁山港海域的环境污染较轻,除港内码头近岸油类超标外,其余区域水质状况良好。但是,港内陆域临岸工程的开发,也引起海域环境质量改变使生态环境受到不同程度的影响。 |

| Abstract: |
| To investigate the sea water quality and sedimental envirenment,12 sampling points were made in the sea area of Tieshan port(109°30'~109°36' E,21°25'30″~ 21°31'30″ N). Sea water was sampled three times for testing water temperature,solinity,pH value,dissolved oxygen,chemical oxygen consumption,nitrate,nitrite,reactive phosphate,oils and suspended matter. Sediment was sampled once for testing Cu,Pb,Zn,Cd,Hg,sulfide and organic matter. The results showed that the sea area in Tieshan port was slightly polluted. Except that the oil contents near the wharfs of the inner port were over standarded, the water quality at other areas was in a good state. But as soon as the near-shore projects in the land areas of the port were set up, the environmental quality of the sea area was bound to be changed and the ecological environment should be effected in different degrees. |
