The grasslands in Inner Mongolia have been facing challenges like drought and pests since 1999, leading to degradation and desertification. However, after 2002, there has been a trend towards restoration. By analyzing data from 1999 to 2004, researchers have identified the reasons behind this vegetation variation. They found that factors like drought and pests have driven the changes, but there are also mechanisms in place for restoration. The study focused on the Xilinguole region and highlighted the problems it faces, along with potential solutions.
