浑河傍河区地下水氮污染来源贡献研究
摘要:针对沈阳浑河傍河水源地地表、河流及地下水氮污染情况，利用Hydrus-1D实现以点代面模拟过程，计算包气带底部淋滤出水的水量和氮素浓度，并将其作为初始值输入由Visual Modflow构建的含水层氮素迁移转化数值模型，实现地表、包气带与含水层系统间模拟计算的结合。此外，结合地下水氮素测试结果，通过均衡公式计算不同地下水氮污染来源的贡献率。模拟结果表明，东南部地下水氨氮的主要污染来源为浑河补给，贡献率为61.79%；西北部地下水硝酸盐氮的主要污染来源为地表垂向入渗，贡献率为43.92%。
Abstract:Focused on the nitrogen pollution of the groundwater and river and ground surface of Shenyang Hun river water source area, Hydrus -1D was used to obtain the water volume and nitrogen concentrations at the bottom of the unsaturated zone, which can be considered to represent the regional results as initial values of the aquifer model built by Visual Modflow, which was used to simulate the nitrogen migration and transformation, and these can combine the simulation in top soil, unsaturated zone and aquifer together. In addition, compared with the groundwater sampling test results, the simulating and calculating results mentioned above were used to calculate the contribution rates of various groundwater nitrogen pollution sources by equilibrium formulas. The conclusions suggested that ammonia nitrogen in the southeast part was mainly from Hun River, and the contribution rate was 61.79%;Nitrate nitrogen in the northwest part was mainly from top soil vertical infiltration, and the contribution rate was 43. 92%.
