摘　　要：2020年4月,课题组对珠江口磨刀门附近水域春季水质状况进行调查,总共布设了20个调查站位,分析了水温、pH、盐度、悬浮物(SS)、溶解氧(DO)、化学需氧量(COD)、无机氮(DIN)、活性磷酸盐(PO^(3-)_(4)-P)、硫化物(S)、油类、重金属元素(汞、铜、铅、锌、镉、铬)、砷、叶绿素a等18项指标。结果显示,大部分水质检测指标均符合国家一类或二类水质要求,水质总体状况较为良好,整体水域海水自净能力较强,除了1个调查站位外并未发现水体富营养化现象。本研究对珠江口磨刀门水域水质状况进行调查分析,可以为磨刀门水域环境保护和管理提供理论指导。In April 2020,the research team conducted a survey on the water quality in the waters near Modaomen of the Pearl River Estuary in spring,and set up a total of 20 survey stations,and analyzed 18 indicators,namely water temperature,pH,salinity,suspended solids(SS),dissolved oxygen(DO),chemical oxygen demand(COD),dissolved inorganic nitrogen(DIN),active phosphate(PO^(3-)_(4)-P),sulfides(S),oils,heavy metal elements(Hg,Cu,Pb,Zn,Cd,Cr),As and chlorophyll a.The results show that most of the water quality testing indicators meet the national first or second class water quality requirements,the overall water quality is relatively good,and the seawater self-purification ability of the overall water area is relatively strong,except for one survey site,no water body eutrophication is found.This study investigates and analyzes the water quality of Modaomen waters at the mouth of the Pearl River,which can provide theoretical guidance for the environmental protection and management of Modaomen waters.
