摘　　要：根据灌溉水分运动规律,建立了水分入渗和土壤蓄水量动态模型。对喷灌、滴灌、渗灌及波涌灌几种方式下,小麦和玉米两种作物的水分入渗和土壤蓄水量动态进行了对比试验和模拟研究,分析了不同灌溉方式的灌溉机理。According to the laws of irrigation water moving, the seeping and moving model of irrigation water are bcilt by the basic equation of soil water. The test and simulation of irrigation water in wheat and corn filed have been studied for sprinkler irrigation, drip irrigation, percolation irrigation and surge flow irrigation. The mechanisms of the four irrigation systems ars analyzed in this paper.

关 键 词：入渗 土壤水分 模拟
