摘　　要：根据莱州湾南岸海水入侵区地下水水质特点,将海水入侵等级划分为4级。同时,选取Cl-,矿化度,SO42-,rHCO3-/rCl-,K-等指标作为评价因子,并分别确定了这5项指标的等级划分范围。然后,运用模糊数学的综合评判方法,对研究区内海水入侵现状做出评价。Based on the characteristics of the groundwater quality in the south coastal seawater-intrusion area of Laizhou Bay, the intrusion degree is divided into 4 grades, and Cl^-, mineralization degree, SO4^-, rHCO3^-/rCl^-, and K in the groundwater are selected as the assessment indices to be determined and graded. Each of the 5 indices has its ranges respectively correspording to the 4 grades. Then the synthetical judgement method in Fuzzy mathematics are employed to study the seawater intrusion status and to conduct the assessment.
