渤海辽宁海湾地化环境与资源开发问题探讨

The Geochemical Environment and Exploration of the Resources in Liaoning bays of Bohai Sea

以1989～1990年海湾志调查的实测资料为基础,研究了营城子湾、金州湾、普兰店湾、董家口湾、葫芦山湾、复州湾、太平湾7个海湾的化学要素含量及分布。通过对海湾环境质量评价得出:目前已遭受磷酸盐、重金属及硫化物的不同程度的污染,且诸化学要素都是在潮流水动力支配下产生迁移和扩散。最后得出营城子等诸湾地化环境现状,提出各海湾资源开发与养殖关系的几点认识。

This paper deals with the results of environmetal investigation of chemical factors in Liaoning bays in Bohao Sea from 1989 through 1990. The results show that the bays have been polluted by wasted water and chemical fertilizers from agriculture in the limited sea area of man-made pollutants. The pollutants are largely phosphate, that is, the phosphate concentration in waters of four bays (Yingchengzi Bay, Jinzhou Bay, Tiaping Bay and Fuzhou Bay) is twice as high as that of the other bays (Pulandian Bay, Hulushan Bay and Dongjiakou Bay) , beyond environmental standard. It is obvious that pollution of metals (Zn) , sulphide and phosphate has been reflected in sediments of wide sea area. According to the results of the synthetic analysis on the pollution level of sea water and sediment, the resource development, utilization and aquaculture are discussed. At the end of the paper, a further a study of the environmental programme and project, prevention and treatment of pollution are also expounded.
