The study looked at how vegetation in Northern Shaanxi Province changed from 2000 to 2010 and how it related to the climate. They found that vegetation growth had three stages during this time, with some areas seeing more growth than others. The amount of rain decreased over the years, while temperatures went up. However, the dry and hot climate didn't get much worse. Some areas had more vegetation when it rained more, while others had less. The temperature was important for plant growth in the summer, and rain affected growth with a delay.
