| Abstract: | The simulation and analysis of soil water content and moving in different precipitation years with math model were conducted. A special black soil on the Songnen plain was used as an experimental base in this study. A databases of soil physical properties and crop growth development and meteorology were established according to long-term measurements. The observed data in 1995, 1997 and 1999 were used to test the performance of the model with simulation of soil water content. Good correspondence was obtained. |
