| 摘 要： | 结合长江中下游地区气候、土壤特征、植被覆盖、降雨、地势及人类活动强度，采用美国通用土壤流失方程确定了各个参数值。在此基础上计算出靖江市全年的土壤侵蚀量，并推出了水稻种植期间的土壤侵蚀量及由此产生的吸附态氮污染负荷量，为农业面源污染防治提供依据。

| Abstract: | In this paper, based on Universal Soil Loss Equation(USLE) and local conditions in the under-middle Changjiang area with its climate, soil properties, vegetation, precipitation, topography and human activities, model parameters are determined, and the annual soil-erosion amount of Jingjiang is then calculated. Specifically, the amount of soil-erosion during the period of paddy planting is derived as well as the induced nitrogen-contaminated amount in the absorbed state,providing the basis for agriculture area-pollution protection. |
