Why has Sichuan Basin always been a battleground for military strategists in history? What is its value?

Historically, Sichuan Basin has been valued by countless military strategists. Many people think that the Sichuan Basin is of great strategic significance to China. At the time of national crisis, the importance of Sichuan basin is more obvious, so that there is? Sichuan will not die, and China will not die? Statement. But in the history of Sichuan, economy, politics, transportation and culture are not the best. Then why does Sichuan basin become a battleground for military strategists, and what is its value?

First, the geographical position is superior. Due to the topography of Sichuan Basin, Sichuan plays a defensive role and has a unique military position. Sichuan borders Tibet, and the Qinghai-Tibet Plateau has become a natural geographical barrier. Because of its special basin attribute, it also creates the situation of eight mountains in one, which is more beneficial to the defensive side. Sichuan has1000000 Dashan basin with an area of16000000 square kilometers. The terrain is dangerous, which can be described as easy to defend but difficult to attack. When defending, we only need to allocate a certain number of teams and keep the key points, so we can get the maximum results with the least loss, which is easy to hit the enemy's morale and economy.

Second, rich resources. Historically, fighting can never become a battleground for military strategists just by geographical advantages. War needs people and food, as well as horses. It takes a lot of money to organize a huge army attack. For the equipment and maintenance of weapons, all the soldiers and horses need money for grain, grass and logistics transportation. Therefore, the army must either have strong financial support or fight to support the war and plunder on the spot. Shu has an advantage in defense, and there are many western Sichuan plains suitable for farming, with more than 20 thousand square kilometers. Rich in products and resources.

Third, the population is large, the soul of Sichuan people. During the Qin Dynasty, a large number of immigrants moved from the Central Plains to the land of Bashu. After Li Bing built Dujiangyan, Sichuan agriculture developed rapidly and reached the peak level of the whole country in a short time. By the Han Dynasty, the population of Shu increased rapidly. More importantly, Sichuan people's indomitable spirit of the war of resistance, in the face of foreign invasion, Sichuan people stand up the national backbone and fight to the death. In the face of Mongolian soldiers, they never give in; After Qing entered the customs, it was decided? Hair or hair? ; During the Anti-Japanese War, the Sichuan Army faced Japan's powerful modern weapons with the worst weapons, but never gave in. Even if the whole army is wiped out, it never gives in.
