Study on the Replacement of Nationalities and Economic Development on the Southeastern Fringe of the Inner Mongolian Plateau

The purpose of this study is to discuss the history of the nationalities' replacement and economic development in the area around the upper reaches of the Luanhe River, which is located on the southeastern fringe of the Inner Mongolian Plateau, by analysing historical documents and archaeological materials, as well as by field investigation. The conclusion is: In this area, there were frequent replacements of nationalities in history, and the process of economic development was often broken. Before the Ming Dynasty, the area had mainly been inhabited by nomadic nationalities, so pasture and hunting were the main modes of production in the area. There was land reclamation in small ranges in the Dynasties of Liao,Jin, Yuan, and late Ming, but that was made only by the garrison troops or peasants, and the crop harvest could only be supplied for themselves. Later, it stimulated the economic overall development that the Qing Dynasty government controlled the Mongolian nationality through conciliation. Since the end of the Qing Dynasty, excessive and extensive cultivation and pasture appeared here, which completely changed the regional landscape in less than one hundred years and resulted in the environmental deterioration.
