The researchers studied how vegetation in the upper Shiyang river basin in China has changed over time in response to climate change. They used satellite data and climate information from 1999 to 2013 to analyze vegetation growth. The results showed that most of the area had an increase in vegetation, with the growing season getting longer. Spring and autumn saw the most significant growth. The study found that precipitation had a bigger impact on vegetation growth than temperature. If temperatures and precipitation continue to rise in the area, vegetation may become less sensitive to these changes.
