清朝200多年间,滇、桂两省同为祖国西南边防体系的有机整体,尤其19世纪中叶法英殖民势力强邻压境后,两省边防建设更是两两相依。戍边艰难的崇山密林烟瘴地清中期前的滇桂边防,大体处于保守无为的状态。究其原因,除了西南边疆无强邻和清政府沿袭历朝中央政权与宗属国或边远失控少数民族地区之间的“内边防务”观念之外,还有一个重要原因是西南边陲恶劣自然环境造成戍边困难,那里崇山绵亘、丛林密布,交通极为不便,还是烟瘴广布之地。 During the more than 200 years of the Qing Dynasty, both Yunnan and Guangxi were the organic whole of the southwest frontier defense system of the motherland. Especially after the French colonial forces and the British were forced to close down in the mid-19th century, border control in the two provinces was even more dependent on each other. The garrison’s difficult Chongshan jungle smog to the border before the Qing dynasty and Yunnan, generally in a conservative state of inaction. The reason is that in addition to the “border defense” concept between the central and northern governments in the southwestern frontier and the Qing government following the control of the central and southeastern provinces and remote areas under the control of ethnic minorities, there is another important reason for the southwestern border being the harsh nature Environment caused by the edge of the difficulties, there Chongshan stretches, dense jungle, traffic is very inconvenient, or wide spread of sooty.
