A case study of Gucheng County was conducted to explore the influence of the four different types of land-use (villages,towns,rural and highways) on the basic farmland from 2006 to 2009.First,the levels of easy-encroached land factor and encroached regions were identified.Then,the changing percent and rates of basic farmland was used to check out the divided result.The results showed that the basic farmland factor can be divided into two classes and the encroached region can be divided into four grades.The easy-encroached land of different years was stable at the same level,and basic farmland occupied varies according to the grades.This research provides some valuable insights for protecting basic farmland.
