Agricultural historical geography is a discipline that studies the evolution of agricultural development, structure and layout in historical periods and the reasons for its formation, and population increase and decrease, cultivated land reclamation and crop planting and layout are the most basic research contents of agricultural historical geography. The first three chapters of this book are the results of this research, mainly using the Ming and Qing dynasties, Shandong and Northeast regions as examples. Chapter 4 uses the archives of Qufu Kongfu to calculate the mu yield and sowing ratio of various grain crops, and establishes a new view formed in the middle and late Ming Dynasty of the two-year three-ripening crop rotation system. In the process of studying the structural changes of food crops, it is believed that the structural importance of historical geography sometimes exceeds its spatiality. Chapters 5 and 6 are the contents of the synthesis and theory related to agricultural history and geography. This book summarizes the four most basic principles of historical geography from the research practice of agricultural historical geography in northern China for the reference of the academic community.
