| Abstract: | By means of artificial precipitation in laboratory,the process of nonpoint nitrate pollution in uncovered slopes was simulated under different rainfall intensities by use of a large soil tank with changeable slope.By synchronous observation of the rainfall,runoff and water quality for the whole process under different conditions,the dynamic variation of pollutant concentration with runoff rate was analyzed.Finally,based on the study on the physical mechanism,a model for calculating pollutant concentration in rainfall runoff was put forward. |

| Keywords: | non-point pollution soil tank artificial precipitation nitrate law of pollution |
