摘要
根据1990～1992年莱州湾部分海域的水质监测结果,利用模糊综合海水水质级数法,对该海域的水质现状进行了综合评价,并对主要污染因子及其分布、变化特征进行了讨论分析,评析结果表明:该海域的综合水质符合二类水质标准;湾内主要污染源是来自小清河、虞河、弥河、白浪河及二山岛的工业与生活污水,其中以小清河、弥河及三山岛为重;该海域的主要污染因子为石油类、无机氮、COD;水质污染的空间分布特征较明显,而年际变化则无明显规律.
With the monitoring data from 1990 through 1992 of water quality of partial area near seashore of Laizhou Bay and by using the method of Fuzzy Set Theory, the status of the water quality of the area is evaluated, and the main pollutants and distributional feature are analysed. It is concluded that 1) the water quality of the area accords with the 2nd grade of GB3097-82 standard; 2) the main pollution sources of the area are the industrial and domestic sewage stemming from several rivers and Sanshandao; 3) the main pollutants are oil, inorganic nitrogen, COD; 4) the water pollution is distinctive in spatial distribution but the annual variation pattern is not apparent.
