Non-point Source Pollution of Nitrogen and Phosphorus Nutrients Using SWAT Model in Tumen River Watershed, China
运用数学模型模拟非点源污染物的空间分布及其输移转化机制,是当前农业非点源污染研究中的重要手段和途径之一.流域尺度长时段分布式水文模型SWAT(soil and water assessment tool)应用于我国南方许多流域的非点源污染模拟上都取得了较好的结果.利用SWAT模型建立了东北图们江流域非点源污染数据库,对该流域(中国一侧)划分为5个小流域46个水文单元,分别进行了水文模拟、降雨径流和土壤侵蚀量计算.结果表明,图们江流域农业非点源污染…查看全部>>
The mathematical model is an important tool and method in the study of agricultural non-point source pollution.It is particularly useful for simulating spatial distribution, as well as the transport and transformation mechanism of non-point source pollutants.SWAT( soil and water assessment tool), a watershed scale and long term distributed hydrologic model, has been applied in the simulation of non-point source pollution in many watersheds of southern China.…查看全部>>
