The researchers studied how vegetation in the Kherlen River Basin changed over time and what factors influenced these changes. They used satellite images to track the greenness of the area from 2000 to 2020 and found that the vegetation remained stable overall, with a notable shift between 2013 and 2017. The variation in greenness across the basin was consistent, indicating minimal external impacts. They also discovered that temperature and precipitation were the main factors affecting the vegetation, with local weather conditions directly impacting plant growth. These findings can help protect the environment and understand how vegetation responds to different factors in the region.
