中文摘要：

三杨庄遗址汉代农田遗迹，是了解当时农田具体形态以及耕作技术的重要考古发现。文献记载的代田法并非一种单纯的土壤耕作技术，其中包含经过中耕等环节、实现叫与亩“岁代处”的中耕技术。汉代赵过所推行的代田法是在此基础上的技术创新。结合三杨庄聚落遗址在汉代的宏观与微观环境，以及汉代冬小麦的种植在黄河中下游地区得到广泛推广的史实，可知该遗址的农田形态正是为适应其周边环境的一种技术选择，这种技术选择与代田法抗旱保墒原理相一致。

The farmland trace of Sanyangzhuang site is the important archaeological discoveries, which helps us understand the farmland shape and the farming techniques in the Han dynasty. Daitianfa（代田法 ） is cultivation technology, the ridge and ditch of the farmland would exchange their positions after cultivation. It was technical innovation that Daitianfa（代田法 ） was carried out by Zhaoguo（ 赵过） in the Han dynasty.
