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 environmental survey data of Dayao Bay, this paper systematically expounds the effects of chemical elements pH, salinity, transparency, DO, COD, TOC, turbidity, suspended solids, NH4-N, NO2-N and NO3-N , PO4-P, SiO3-Si, Cu, Pb, Zn, Cd, As, Hg, Cr, sulfide, HCH, petroleum and so on. The main elements in the tide of hydrodynamic domination, the formation of diffusion zone. Only the content of inorganic nitrogen and PO4-P in each element exceeded the standard, and the content of other elements were in the normal concentration of seawater, which belongs to a kind of seawater quality. The article also carries on the correlation analysis to each factor.
