Preliminary Study on Southwest China's Geopolitical Structure around Revolution of 1911 ——Investigation from the Point of Interprovincial Traffic System

The inter-provincial traffic system through the San Yan Zone(三沿地带,along the river,border and coast) enhanced the regional contact of Southwest China's provinces around the time of 1911 Revolution.It embodied rich political significance under the background of the frontier crisis,and resulted in the geopolitical structure of the internal combination and outward extension among the provinces of Southwest China.Southwest China's peripheral four provinces(Sichuan,Hubei and Hunan and Guangdong) form an arc that extended from northwest to southeast,which encircled the three internal provinces(Yunnan,Guizhou and Guangxi).The peripheral four provinces were the perimeter barrier and outward channel of internal three provinces.There were some political movements organized in the seven Provinces such as Railway Project Crisis.It showed that there was an obvious geopolitical interaction trend among the seven Provinces.In 1913,Southwest Association was organized by some representatives from the seven provinces which fully embodied the geopolitical structure in Southwest China.
