The researchers used GIS technology to study how different types of vegetation in Qinling Mountain are influenced by factors like altitude, rainfall, temperature, slope, and aspect. They found that altitude is the main factor affecting vegetation distribution, with changes occurring as altitude increases. Water and heat gradients also play a role, while slope and aspect have less impact. The study identified the best environmental conditions for each type of vegetation and showed how they are distributed across the mountain. Overall, the research showed that combining ecological analysis with GIS is an effective way to understand vegetation-environment relationships in Qinling Mountain.
