| Abstract: |
| This paper analyzes the research advances of mathematical simulation for water flow in surface irrigation at home and abroad,and probes into the shortages in present researches and the urgent subjects to be studied in the future. It indicates that emphasis should be put on the following subjects in the future: the determination of field infiltration coefficient and roughness coefficient;the optimal combination of field standard and irrigation technical index,and the rational ground levelness degree and modes for different regions and crops;the water flow movement and rational irrigation technical indexes under long-border subsection irrigation,stepped level border irrigation and film mulching irrigation;and the influence mechanism of muddy water irrigation and soil air obstruction to surface water movement. |
