3.6 Analysis of MESS of potential area of distribution of PWD under future climate change scenarios.
The distribution of the climate anomaly area (S ≤ 0) in the entire potential distribution area was low under the future climate scenarios (Fig. 9). No suitable habitat area for PWD was predicted in the climate anomaly area compared with the potential distribution area under the same climate scenarios (Fig.9). The average similarity values of the 647 modern effective distributional points for PWD were 7.73, 6.08, 9.13, 9.15, 5.74, and 5.12, respectively, under SSP1-2.6, SSP2-4.5, and SSP5-8.5 in the 2050s and under SSP1-2.6, SSP2-4.5, and SSP5-8.5 in the 2070s. This indicated that the degree of anomaly was higher in the 2070s SSP5-8.5 climate scenario. The abnormal degree of the other five climate scenarios was low.
