摘要
以改进层次分析法(AHP)权重值研究为目的,通过对数据的标准规范化处理自行构造判断矩阵,采用MATLAB计算研究区地下水质的权重值,将所得权重值运用于灰色关联和模糊综合评价两种方法,以白城地区为例对地下水中铁、砷、氟等9项指标进行评价。结果表明:铁、钠、氯化物、硝酸盐(N)、硫酸盐、溶解性总固体、总硬度、砷、氟的权重分别为0.137、0.105、0.130、0.113、0.106、0.070、0.057、0.209、0.073。两种方法评价结果具有较高的空间一致性,白城地区水质总体较差,Ⅰ～Ⅴ类水占比分别为12%、13%、9%、14%、52%,西北部洮儿河扇形地区水质远优于东南部平原区。通过两种方法的适用性验证,表明改进的AHP法是符合实际的。
In order to improve the study of weight values in AHP, the improved method constructs the judgment matrix by standardizing the data, and uses MATLAB to calculate the weight value of the groundwater quality in the study area, applies the weight value to the grey correlation and fuzzy comprehensive evaluation. Take the Baicheng area as an example in groundwater. 9 indicators such as iron, arsenic and fluorine are evaluated. The result shows that the weights of iron, sodium, chloride, nitrate(N), sulfate, total dissolved solids, total hardness, arsenic and fluorine are 0.137, 0.105, 0.130, 0.113, 0.106, 0.070, 0.057, 0.209, 0.073 respectively. The results of the two methods have high spatial consistency. The overall water quality of Baicheng area is 12%, 13%, 9%, 14%, and 52%respectively. The northwestern part of the river is fan-shaped. The water quality in the region is far superior to that in the southeastern plains. Through the applicability verification of the two methods, the result shows that the improved AHP method is practical.
