THE CHANGE CHARACTERISTICS OF BIOGENIC ELEMENTS AND THEIR INFLUENCING FACTORS IN TIESHANGANG PORT

本文根据1999年12月的调查资料,分析探讨了广西沿海东部铁山港湾生原要素的变化特征及其影响因素。结果表明:本水域生原要素含量不高,与相邻的北海湾相比略低,但与1984年岸调的结果相比,N和Si呈上升趋势,P则呈下降趋势;N以陆源输入影响为主,而P和Si则以有机体分解的再生过程影响为主。

Based on the investigation on December 1999, the change characteristics of biogenic elements and their influencing factors in Tieshangang bay in the eastern coastal area of Guangxi were studied. The results showed that the contents of biogenic elements in Tieshangang bay were not high, and were lower than those in Beihai bay. Compared with the investigation results in 1984, it showed that the N and Si contents increased while the P contents decreased. N was mainly influenced by the input from land. And P and Si were mainly influenced by the regeneration of organism decomposition.
