| 摘 要： | 为研究土壤养分流失在流域内不同地貌单元的运移问题,通过建立小流域土壤养分运移数学模型及计算程序的编制,实现了对小流域土壤养分运移的数值模拟.该模型能描述小流域水土流失的水量及养分含量的运移过程,解决了养分源成点源、非点源分布和小流域土壤养分呈带状分布变化的问题,为大面积预测养分运移提供了科学依据.

| Abstract: | In order to research the soil nutrient in small river basin,the mathematical model of soil nutrient transport in small river basin and calculating program are established. The model can simulate soil nutrient transport in small river basin. The transport model can describe the transport process of water flow and nutrient loss in small river basin.The problem of nutrient sources as point, non-point and belt scattered ware solved. It provides scientific basis for predicting nutrient transport trend in a large area. |
