| 中文摘要: |
| 本文运用模糊数学的基本思想方法，根据海水入侵地下水水质的特点，选择了Cl-,M等5项化学指标作为综合评判海水入侵程度的指标：侵染程度划分为4级；把模糊数学最大隶属度原则应用到海水入侵地下水水质评价中，构造了综合评判模糊数学模型，并进行了实例计算，通过对比运用模糊数学的评价结果与运用地下水水质量，标准规定的加附注的评分法的评价结果，验证了此评判模型的可靠性。 |
| 英文摘要: |
| A mathematical model for evaluating seawater intrusion based on fuzzy theory is developed.Five hydro chemical indexes, including Cl-,M,SO2-4,Br and SAR, for characterizing the water quality are suggested to evaluate the intrusion and used for intrusion degree ranking.The intrusion degree is divided into four levels.The application of this method to evaluate the water quality in a well is given as an example for demonstration.The comparison shows that the evaluation result of this method is in accordance with that by means of conventional method. |
