The study used satellite images and computer models to look at how the land in Xianning City changed from 1996 to 2005. They found that more forest and buildings were growing, while farmland was shrinking. The change in land use led to an increase in the value of ecosystem services. The biggest changes were turning farmland into forests and buildings. Overall, the city's land became more ecologically balanced over time. The researchers showed that using satellite images and computer models can help us understand how land use changes affect the environment.
