气候、政策与环境:秦汉时期内蒙古地区环境变迁的历史考察

Climate,Policy and Environment: Historical Investigation of Environmental Changes in Inner Mongolia during the Qin and Han Dynasties

内蒙古地区自仰韶文化温暖期结束之后,逐渐形成了以草原为典型环境的生态变迁,内蒙古地区的人类社会也随之由原始农业社会向典型游牧社会过渡,并逐渐形成了以游牧经济为基础的人类社会形态,秦汉两代也是游牧社会的初步形成时期。但受到秦汉时期移民及土地开垦等的影响,内蒙古地区尤其是游牧与农耕民族接触地带的自然环境也在此时期发生了一定变迁,受到东汉以来气候转寒的影响,游牧经济的影响范围有效向南拓展,这对于已破坏自然环境的恢复发挥了一定作用,却也因气候波动时期内灾害多发而加剧了人对自然环境的破坏性影响。

After the warming period of Yangshao culture in Inner Mongolia,Inner Mongolia gradually formed the ecological change with the grassland as the typical environment.Inner Mongolia's human society also shifted from the primitive agricultural society to the typical nomadic society and gradually formed the basis of nomadic economy Human social formation.Qin and Han dynasties were also the initial formation of nomadic society.However,due to the impact of Qin and Han dynasties'emigration and land reclamation,the natural environment of the nomadic and agrarian contact areas in Inner Mongolia also changed during this period.However,the influence of nomadic economy has been affected by the cold climate in Eastern Han Dynasty Expansion to the south has played a role in the restoration of the damaged natural environment but has also exacerbated the devastating impact on the natural environment caused by the frequent occurrence of disasters during times of climate change.
