The study used a fuzzy clustering method to analyze plant community succession in a hilly region. They found that 13 sample plots with 15 species were classified into 5 formations, showing a clear progression from Artemisia scoparia to Hippophae rhamnoides communities. This method was effective in studying plant succession, providing precise results with simple calculations that can be done on a computer. The findings align with traditional methods, demonstrating the value of this approach in understanding how plant communities change over time.
