The study looked at how vegetation in a specific area of China is affected by both climate change and human activities. They used a method called Savitzky–Golay filtering to analyze satellite data on vegetation. The researchers found that overall, vegetation in the area increased over time, with the most growth seen in cultivated land. Different seasons also showed varying levels of vegetation cover change, with autumn seeing the most significant increase. The study also found that areas with more precipitation and higher temperatures tended to have more vegetation. Climate change alone caused an increase in vegetation in about two-thirds of the area studied, with some regions showing significant growth.
