摘要
本文依据大窑湾的环境调查资料为基础，系统地阐述了水体中化学要素ｐＨ、盐度、透明度、ＤＯ、ＣＯＤ、ＴＯＣ、浊度、悬浮物、ＮＨ４－Ｎ、ＮＯ２－Ｎ、ＮＯ３－Ｎ、ＰＯ４－Ｐ、ＳｉＯ３－Ｓｉ、Ｃｕ、Ｐｂ、Ｚｎ、Ｃｄ、Ａｓ、Ｈｇ、Ｃｒ、硫化物、六六六、石油等分布规律。诸要素主要是在潮流水动力支配下，形成扩散带。各要素中仅有无机氮和ＰＯ４－Ｐ两项含量超标，其余要素含量范围都是处于海水正常浓度水平，属于一类海水水质。文章并对各要素进行相关关系分析。
Based on the results of the environmental investigation in 1992,the distributive regularities of the factors in the water column of Dayao Bay,such as pH,DO,COD,TOC,salinty,turbidity,suspended matter,transparency,nutrients(NH4-N,NO2-N,NO3-N,PO4-P,SiO3-Si),heavy metals(Cu,Ph,Zn,Cd,Hg,Cr),As,sulphide,666,oil etc.are summarized systematially in this paper.Through analysis,it was found that only inorganic N and PO4-P contents of the various factors had exceeded the standards,the rest being all at the normal concentration levels.Thus the Dayao Bay water belongs to class A sea water.A correlation analysis has been made of the various factors.
