(3) As altitude
increased, H0 and E gradually became smaller, while C showed the opposite pattern, and J did not significantly
change. The similarity coefficients analysis demonstrated a clear difference among belts; the farther
apart any two belts, the smaller the similarity coefficient, indicating less similarity in the butterfly
communities. The similarity coefficient between the deciduous forest and the coniferous–deciduous
mixed forest belt was the largest (0.651) while that between the deciduous forest and the alp tundra
was the smallest (0.141). (4) Comparison of the butterfly species communities among different months
in the coniferous–deciduous mixed forest found that H0 and E showed similar directional changes, while
the opposite pattern was found with C; the changes in J did not necessarily reflect the actual change in
diversity.
