根据1987年6月、8月、11月和1988年2月的历史资料,估算了伶仃洋水域活性硅酸盐的输入通量,研究了活性硅酸盐与盐度间的相互关系及磷、氮和硅之间的比值。结果表明,通过四大口门输入伶仃洋的硅通量为185×10~4t/a;回归分析的结果表明,除1988年2月外,其他航次硅酸盐与盐度间呈高度显著负相关,呈保守性,枯水期(1988—02)硅酸盐存在生物转移.转移量为18.2％。磷、氮、硅之间的平均比值,丰水期表层1:62:149,底层为1:47:90;枯水期表层为1:98:175,底层为1:93:172。
According to the historical data of June 1987, August, November and February 1988, the input fluxes of active silicates in Lingdingyang waters were estimated. The correlation between active silicates and salinity and the relationships between phosphorus, The ratio between nitrogen and silicon. The results show that the flux of Si input to Lingdingyang through the four main gates is 185 × 10 ~ 4t / a. Regression analysis shows that there is a highly significant negative correlation between silicate and salinity except for February 1988 , Was conserved, and there was biotransformation of silicate during the dry season (1988-02). The amount of translocation was 18.2%. Phosphorus, Nitrogen and Silicon. The average ratio of 1:62:49 in the wet season was 1:47:90 in the wet season, 1: 98: 175 in the dry season, and 1:93:17 in the bottom.
