【摘要】：三杨庄遗址汉代聚落位于黄河河滩地上,聚落居民修筑了民堤以保护自身的安全,一般的季节性洪水泛滥对汉代聚落及其农业生产活动并不构成威胁。三杨庄遗址汉代文化层的土壤以粉砂质粘土和粉砂质壤土为主,粉砂含量相对较高,透水性较好,在正常雨量下,不易形成长期内涝和地面径流的情况。西汉晚期至东汉初期,三杨庄遗址的气候正处于干冷期,且持续时间较长,降水量相对较少。在这样的耕作环境下,三杨庄遗址汉代农田u=u]相间的形态,可能是与代田法类似的种植于u=内的抗旱保墒技术体系,而不是为排涝设计的。
[Abstract]:The settlement of Sanyangzhuang site in Han Dynasty is located on the beach of the Yellow River. Residents built dikes to protect their own safety. The general seasonal flood did not pose a threat to the settlement and its agricultural production activities in the Han Dynasty. The soil of Han culture layer of Sanyangzhuang site is mainly silty clay and silty loam. The silt content is relatively high and the permeability is good. Under the normal rainfall, it is not easy to form long-term waterlogging and surface runoff. From the late Western Han Dynasty to the early Eastern Han Dynasty, the climate of Sanyangzhuang site was in a dry and cold period, and lasted for a long time, and the precipitation was relatively small. In such a farming environment, the interphase pattern of farmland in the Han Dynasty of Sanyangzhuang site may be similar to the technical system of drought resistance and soil moisture conservation planted in u=, rather than designed for drainage.
