在解读丰县“免料始末”以及复原治河材料历史演变过程的基础上,分析了黄河治理与作物种植结构变化的内在关系。研究表明,清雍正间秫秸演变为主要的治河材料后,河工建设与普通百姓的关系愈加紧密,为应对河工派料,农作物种植结构发生了明显的变化,表现为人为影响下高粱种植面积的增减。 Based on the analysis of the history of Fengxian County’s “No Materials” and the historical process of rehabilitating the river materials, this paper analyzes the inherent relationship between the Yellow River governance and the crop planting structure changes. The research shows that the relationship between river construction and ordinary people has become more and more close after the shoal of Qing Emperor Yongzheng evolved into the main river-controlling material. In order to deal with the river feeding, the planting structure of crops has undergone obvious changes, manifested as anthropogenic sorghum planting area Increase or decrease.
