The study looked at how vegetation in the Yellow River Basin in China has changed over the past 30 years in response to climate factors like temperature, precipitation, and sunshine duration. They found that the vegetation has been increasing, with most areas showing positive growth. The temperature has been rising, with higher temperatures in the southeast. Precipitation has been increasing slightly, while sunshine duration has been decreasing. Overall, the vegetation growth is positively linked to temperature and precipitation, but negatively linked to sunshine duration.
