FIGURE 6 Potential distribution area of each species predicted
by the MaxEnt model. The habitat suitability will be evaluated as high,
if HIS value is between 0.40 and 0.60, and optimal if HIS value is
between 0.60 and 1.00
In addition, we adopted ArcGIS 10.4 software to superimpose the
appropriate potential distribution areas of each species (HSI ≥ 0.4) to
obtain the potential distribution pattern of species richness (Figure
7). The results showed that on the grid scale with a resolution of 0.05°
× 0.05°, the potential species richness of each grid ranged from 0 to
12. Through a combination of the distribution of the existing national
and provincial nature reserves in Northwest Yunnan together with the
administrative division of this region (for more details, see Ye et al.,
2020a), we found that part of the grids with the highest potential
species richness were located near Baima Snow Mountain and Gaoligong
Mountain NNRs, while the other part of the grids with the highest
potential species richness were situated in Shangri-La County (Figure
7).
