在元朝统治的100余年间,包括今云南、广西、贵州在内的西南边疆地区,再次归入中国统一王朝的统治下,西南边疆以后未再发生分裂,这与蒙元的积极经营分不开。元朝十分重视经营西南边疆,在设治、屯田、交通、矿冶业等方面都取得很大成就。元朝在西南边疆实行土官制度,开创了封建王朝统治蛮夷政策南北有别的时期,并产生了深远的历史影响。 In the more than 100 years of the rule of the Yuan Dynasty, the southwestern frontier areas including Yunnan, Guangxi and Guizhou, once again under the rule of the reunification of China, did not split again after the southwest frontier, which was inseparable from the active management of the Mongolian Yuan . The Yuan Dynasty attached great importance to the operation of the southwestern frontier and made great achievements in the areas of governing, stationing, transportation, mining and metallurgy, and so on. The Yuan Dynasty carried out the system of native officials in the southwest borderland and created a different period between the north and the south during the rule of the feudal dynasty and its barbarian rule, and had a far-reaching historical impact.
