3.3 Current potential distribution
Table 3. The potential distribution areas of PWD under current climatic conditions.
The potential distribution of PWD mainly distributes in central and southeast China under the current climate scenario (Fig. 5). According to the classification of suitable habitats, the areas of suitable habitat in each province were calculated (Table 3). The suitable distribution area of PWD was 197.26 × 104km2, the area of highly suitable habitat was 44.11 ×104 km2, the area of moderately suitable habitat was 55.27×104 km2, and the area of poorly suitable habitat was 97.88 ×104km2 (Table 4). Hunan, Jiangxi, Hubei, Guangdong, Anhui, Chongqing, and Guangxi have relatively large areas of highly suitable habitat. The area of highly suitable habitat in Jiangxi is 7.84 ×104 km2, ranking first in China. Guangxi, Hunan, Sichuan, Jiangxi, and Hubei have moderately suitable habitat areas than other provinces. There is no suitable distribution area of PWD in Gansu, Ningxia, and Xinjiang.
