Abstract:
In this paper, a mathematical model for evaluating seawater intrusion comprehensively based on fuzzy math and improved analytic hierarchy process is founded. The model takes the invasion degree of seawater as the evaluation object and chooses five hydro-chemical indexes as evaluation indexes, including Cl-, Br-, SO42-, K+ and SAR (sodium adsorption ratio), the weight of each index is calculated by the improved analytic hierarchy process and the comprehensive evaluation was carried out by fuzzy mathematical method. Taking Zhaoyuan of Shandong Province as the study area, we use the evaluation model to evaluate the degree of seawater intrusion in this area, the results of evaluation are more reasonable and accurate than the results evaluated by the single index evaluation method, and can provide scientific basis for prevention of local seawater intrusion. The research shows that the model is a simple, efficient and reasonable method for evaluating the degree of seawater intrusion, also can be popularized and applied.
