契丹人的起源与其所生存的环境息息相关,独特的自然地理环境是契丹产生发展的根源。地理因素所自带的天赋性、致命性、地缘差异性和可变性都带动了契丹族群的变迁与发展,同样,契丹族的地缘因素也是影响其崛起和发展的重要因素。 The origin of the Khitan people is closely related to the environment in which they live. The unique natural and geographical environment is the source of Khitan’s development. The natural factors, fatalities, geographical differences and variability inherent in geographical factors have all contributed to the change and development of the Khitan ethnic group. Similarly, the Qidan ethnic group’s geography has also played an important role in its rise and development.
