The study looked at how climate factors like temperature and precipitation affect the growth of grasslands in Inner Mongolia, China. They used two methods to analyze the relationship between vegetation growth and climate at different times of the year. The researchers found that vegetation growth is strongly influenced by temperature and precipitation, with different patterns in different seasons. They also discovered that analyzing the relationship between vegetation and climate is more accurate when considering the types of climate in the region. Overall, they concluded that the method used during the growing season is better for studying this relationship.
