中文摘要
针对非点源污染模型在缺资料流域应用较为困难的问题,以赣江袁河流域为例进行研究。通过插补延长、参数移用等技术手段处理分析,构建了基于分布式SWAT模型的袁河流域非点源污染模拟方案。对流域内水量、泥沙及主要污染物氨氮(NH3-N)和总氮(TN)模拟计算结果显示,纳西效率系数和相关系数基本达到0.7以上,模拟精度较为满意,说明了SWAT模型在资料缺乏流域应用的可行性。所用的技术方法对其它流域的类似研究具有一定的参考价值。
英文摘要
The non-point source pollution was studied in data scarce catchments.A case study was conducted in the Yuanhe River.SWAT model was applied for the simulation of ammonia(NH3-N) and total nitrogen(TN) in Yuanhe River and satisfactory results were obtained, through some technical approaches to deal with the limited available data. Results indicated that SWAT model can be applied in data scarce catchments for the prediction of non-point source pollution.
