摘　　要：基于1985~2003年青岛海洋倾倒区水质监测资料,应用环境质量分级与评价的模糊综合-加权平均复合模型对青岛倾倒区海水水质现状及1985~2003年各年度海水水质进行了综合评价,并在此基础上分析了18 a间的海水水质变化趋势。结果表明：20世纪90年代由于受倾倒的疏浚物中污染物影响,海水水质较差,均为Ⅱ级水质,2000年后海水水质一直维持良好,均为Ⅰ级水质。历年水质优劣顺序为：2000〉2002〉2003〉1997〉1985〉1991年。Based on the investigation data in the Qingdao dumping areas from 1985 to 2003, the fuzzy comprehensive judgment and weighted average method was used to evaluate the seawater quality and the variation of seawater quality. The results show that dumping contaminated dredged material caused a certain degree of degradation to the quality of the seawater in 90s, which belonged to the second level, and it maintained the good state in recent years, which belonged to the first level. The order of better seawater quality during eighty years was 2000, 2002, 2003, 1997, 1985, 1991.
