| Abstract: |
| The temporal-spatial variation of soil moisture content was studied through measuring soil moisture along the slope plot using neutron probe in a manmade Caragana korshinskii slope plot.In addition,temporal-spatial change of distribution of soil moisture content was simulated and predicted.The Results indicated that the change of soil moisture content in 0～400 cm depth was consistent from upslope to down slope.Soil moisture increased greatly in rainy seasons,changed a little in winter and decreased rapidly from spring to next rainy season.Soil moisture content increased along the slope from upslope to down slope,while soil moisture expense increased along the slope,too.The relationship between soil moisture content,slope position and time can be expressed through a binary cubic polynomial. |
