水化学环境是海洋生态系统中的一个重要环节,与生产力密切相关。水化学环境的研究对于开发海洋和发展海洋水域生产力有着极其重要的意义。渤海三面为陆地所围,黄河、海河、滦河等沿岸数十条河流携带大量营养物质入海,是海洋生物繁殖的物质基础。因此,渤海是许多经济鱼、虾的索饵场和产卵场,亦是我国北方的一个重要渔场。本文主要根据作者在1983年的调查资料对渤海湾及其东部水域的水化学要素(S,pH,NO_3-N,NO_2-N,NH_4-N和PO_4-P)的分布及相互关系进行讨论。
Hydrochemical environment is an important part of the marine ecosystem and is closely related to productivity. Research on the chemical environment of water is of great significance for the development of the oceans and the development of the productivity of marine waters. Three sides of the Bohai Sea are surrounded by land. Dozens of rivers along the banks of the Yellow River, Haihe River and Luan River carry a large amount of nutrients into the sea and are the material basis for the reproduction of marine life. Therefore, the Bohai Sea is the feeding and spawning grounds for many economic fish and shrimp. It is also an important fishery in the north of our country. This paper mainly discusses the distribution and interrelation of water chemical elements (S, pH, NO_3-N, NO_2-N, NH_4-N and PO_4-P) in Bohai Bay and its eastern waters according to the author’s survey in 1983.
