非点源污染模型研究

A study on the non-point source pollution model

  • 摘要: 描述了土壤侵蚀的物理过程,分析了影响土壤侵蚀过程的主要因素,提出包括降雨径流模型、土壤侵蚀模型和畜禽污染模型的非点源污染模拟模型(NPSP),并介绍了该模型在爱尔兰Dodder流域的应用.

     

    Abstract: Non-point source pollution, also called diffuse source pollution, mainly caused from the soil erosion and sedimentation, livestock wastes, and agricultural land (pesticide and other poisonous chemical components).In this article, the physical process of soil erosion was described, the main factors which would affect the soil erosion process were discussed, and the non-point source pollution (NPSP) model, which consists of the rainfall-runoff sub-model, the soil erosion sub-model (American USLE), and the livestock wastes sub-model, was constructed.Finally, the experiences and conclusions of the NPSP application in the Dodder Basin of Ireland was introduced.
