摘要
传统的地表水环境质量模拟模型,无法分析地表水中污染物的迁移变化特征,缺乏一定的通用性。为了模拟长期管理措施变化对复杂流域的影响,减少模型对实测数据强烈的依赖性,提出一种基于SWAT的地表水环境质量模拟模型。结果表明,研究所提出的模型负荷量平均预测精度97.68%,总氮磷通量预测的最小相差百分比为0.10%,性能良好;水体中的砷和氟化物污染来源为热泉水输入、矿物质淋溶和河水蒸散富集。
Traditional simulation models for surface water environmental quality may face issues such as inability to study the migration and change characteristics of pollutants in surface water and a lack of universality.To simulate the impact of long-term management measures on complex watersheds and reduce the strong dependence of the model on measured data,a SWAT based surface water environmental quality simulation model is proposed.The results show that the average prediction accuracy of the model load proposed by the research institute is 97.68%,and the minimum difference percentage for predicting total nitrogen and phosphorus flux is 0.10%,indicating good performance.The sources of arsenic and fluoride pollution in water bodies are hot spring water input,mineral leaching,and river water evaporation and enrichment.
