Abstract: The domestic studies on China's geopolitics in recent years can be roughly divided into two categories: the one focuses on international politics to study China's outward-geopolitical situation, the other is rooted in military geography to study China's inward-geopolitical situation. According to the second approach and based on the historical and geographical perspective of traditional struggles among land powers, that the geopolitical situation of the grand northern onshore China can be divided into five parts—a core region, an upstream belt, four corridor belts, seven significant regions and two pivot regions, Among them, the Nanyang-Jianghan significant region and the Shanxi pivot region play a vital role in the whole China’s geopolitical situation, in additions, there are many important relations between the upstream belt, the Northeast significant region, the Xinjinag significant region and China’ outward-geopolitical situation.
