Research Framework & Key Issues for Non-Point Source Pollution in Agriculture Induced by Water-Loss and Soil-Erosion

Abstract:

Water and soil resources are important material basis, upon which human subsistence and development are relying. In the meantime, they are also the fundamental conditions for agricultural production. With the development of human activities and irrational exploitation of water and soil resources, the problem of water loss and soil erosion has caught the attention of the world. Water-loss and soil-erosion dominated non-point source pollution in agriculture, due to its very nature of direct combination with regional food security and ecological safety, is now ascending to a problem of regional-resources. This paper firstly introduced the definition and characteristics of water-loss and soil-erosion dominated non-point source pollution. Secondly a technical framework which was primarily supported by simulation of non-point source pollution in regional agriculture, identification of the mechanism for water-loss and soil-erosion dominated non-point source pollution and the scheme against it is established. Finally key issues such as load module construction for semi-distributed non-point source pollution which based upon component structure, theory and method for total quantity control, and charting the sets of solutions and countermeasures were discussed. The paper may help to establish a theoretical foundation for later research.
