In 2014, national territorial area of Sichuan was 486,000 square kilometers, accounting for 5.1% of national total ranking No. 5. But due to the large population, per capita area is lower than national average, leading to serious problems of large population but small land.

According to the second general survey of soil, there are a total of 25 great soil groups, 66 subclasses, 137 soil genus and 380 soil species.

There are 8 first-grade land use types (table 1), 45 second-grade land use types and 62 third-grade land use types. Except for rubber gardens, Sichuan has all the first and second-grade land use types in other provinces, which is very typical in China.
