中文摘要: |
对近10多年来地面灌溉水流运动数值模拟方面的国内外研究进展进行了归类整理,并就目前研究中存在的不足和未来急待深入研究的问题进行了探讨,认为在今后的研究中应把地面灌溉入渗参数和糙率的确定问题,不同地区和作物条件下合理的田块尺寸与灌水要素的优化组合研究及经济合理的田间土地平整度及平地模式的研究,长畦分段灌、阶式水平畦灌、覆膜灌溉条件下的水流运动和合理灌水技术指标的研究,浑水灌溉和土壤气阻对地面灌溉水流运动的影响机理研究等作为重点内容。 |
英文摘要: |
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. |
