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甽畝相间的形态,可能是与代田法类似的种植于甽内的抗旱保墒技术体系,而不是为排涝设计的。
The settlement of the Sanyanzghang site is located on the floodplain of the Yellow River in the Han dynasty. The embankments were necessarily constructed to prevent the deluge of the Yellow River, so the seasonal floods couldn＇t threaten the settlement and the agriculture. The soil texture of the settlement of the Han dynasty consists of silty clay and silty loam. Because the high content of silt, the chance of long term wa- terlogging and runoff was lower in the conditions of normal rainfall. Between the late Western Han dynasty and the early Eastern Han dynasty, a cold and dry climate lasted considerably long. In such cultivation environ- ment, the technique of cultivating farmlands with alternate ridges and ditches is probably similar to the techno- logical systems of Daitianfa, crops in the ditches to better storage capacity and strengthen drought resistance, not projected for the sake of drainage.
