摘要
应用基于经典广义流域负荷函数(GWLF)模式开发的区域营养盐管理模型,以天津市饮用水水源地于桥水库上游沙河流域为研究对象开展模拟实践研究。本研究基于我国可获得数据量的一般水平,实现了对沙河流域氮污染物环境行为过程的评估,包括对产流量和溶解态氮通量在月尺度上的模拟,以及对溶解态氮污染物的来源进行源解析,模拟精度可靠,结果能够满足管理需求,可作为该模型在我国的进一步推广应用的例证与参考。
Regional nutrient management model was developed based on original generalized watershed loading functions(GWLF) to implement a case study in the drinking water sources of Tianjin City.The main environmental actions of SHR watershed were estimated,including the simulations of streamflow and dissolved nitrogen(DN) load fluxes in monthly scale,as well as the analyses of DN pollution source apportionment.The modeling result could meet the requirements in management with a reliable modeling accuracy,which is valuable for demonstrating in referenced area.
