The study looked at the variety of plants in a shrub forest in Gansu Baishuijiang natural reserve. Researchers used different measures to calculate the diversity of species in the forest. They found that the forest has a wide range of plant species, showing that it is rich and diverse. The presence of many different species indicates a healthy ecosystem. However, human activities have had a negative impact on the dominance of certain species in the forest. The study suggests ways to protect the biodiversity of the forest and how it connects to the local economy.
