The study looked at the plant diversity in Luofu Mountain, Guangdong, using ecological methods. They found that the area has high plant diversity due to its favorable climate conditions. Different elevations in the mountain showed varying levels of plant diversity, with lower elevations having more species. The study also showed that different types of forests in the area had different levels of diversity, with monsoon evergreen broad-leaved forests being the most diverse. Overall, the research suggests that habitat quality and elevation play a significant role in determining plant diversity in the region.
