广西沿海海水中化学要素之间的关系

本文基于多元回归法,根据广西沿海水域的23个站的水化调查资料,进行统计学处理,建立了营养盐与 PH 及耗氧量(垂直分布)、营养盐与 PH 及耗氧量(底层水)、盐度与各种化学要素的数学关系式。对海水中的氮、磷、硅、溶解氧、表观耗氧量、盐度等它们之间的相关关系进行了初步探讨,得出如下结论:(1)氮、磷、硅三者之间,磷与氮的相关性比磷与硅的相关性密切。(2)氮、硅与 PH 之间的关系较它们与 AOU 之间的关系密切,而磷与 AOU 的关系则比其与 PH 的关系密切。(3)盐度对各化学要素的影响此各化学要素之间的相互影响要大得多。

THE RELATIONSHIP BETWEEN CHEMICAL ELEMENTS IN THE SEAWATER OF GUANGXI COAST

Basing on statistical multielement regression analysis method,this pa-per makes a preliminary study on nitrate,phosphate,silicate,dissolved oxysen,Aou,PH,salinity and temperature in the seawater collected from 23 stations of the coastal area in Guangxi,and set up mathematical formular of the relationship between them in vertical and bottom distribution in seawater.Thus get the following conclusion:
1) Among inorganic nitrogen,phosphorus and silicon,the interrelation between nitrogen and phosphorus is closer than that of phosphorus and silicon.
2) The interrelation between nitrogenor silicon and PH is closer than that of nitrogenor silicon and Aou,and the interrelation between phosphorus and Aou is closer than that of phosphorus and PH.
3) The effect of satinity on chemical elements is much greater than the interaction of chemical elements themselves.
