摘　　要：基于28个采样点2018年雨季和旱季19项指标的监测数据,运用改进的灰色关联法评价了流溪河流域的地下水质量,并结合流溪河流域地下水的实际情况,与单因子评价法的评价结果进行了对比。改进的灰色关联法评价结果表明,研究区地下水质量综合评价结果较好,雨季优于旱季,基岩裂隙水优于松散岩类孔隙水,中游优于下游。单因子评价法和改进的灰色关联法的评价结果差别较大甚至部分结论完全相反,比较而言改进的灰色关联法的评价结果更符合实际。Based on the monitoring data of 19 indicators of 28 sampling points in rainy season and dry season in 2018,improved grey correlation method is used to evaluate the groundwater quality of Liuxihe River Basin.Combined with the actual situation of groundwater in Liuxihe river basin,the evaluation results are compared with the single factor evaluation method.The results of improved grey correlation method show that the comprehensive evaluation results of groundwater quality in the study area are better,the rainy season is better than the dry season,the bedrock fissure water is better than the loose rock pore water,and the middle reaches is better than the downstream.The evaluation results of single factor evaluation method and improved grey correlation method are quite different,and even some conclusions are completely opposite.In comparison,the evaluation results of improved grey correlation method are more in line with the reality.
