3.3 Potential distribution of Satyrium ciliatum, Satyrium nepalense, and Satyrium yunnanense.
S. ciliatum are mainly distributed in Southwest China (Fig. 6). Highly suitable habitats are located at the border of Yunnan and Sichuan. Eastern Yunnan and Southern Sichuan have moderately appropriate environments. Poorly appropriate habitats cover a broad area, primarily in Northern and Central Yunnan, Southern Tibet, Western Sichuan, and Western Guizhou. There is also a sporadic distribution in Western Guangxi.
S. nepalense are mainly distributed in Southwest China. Highly suitable habitats are distributed in Central Yunnan. Western and eastern Yunnan, as well as southern Sichuan, have moderately appropriate environments. Poorly suitable habitats are located in Southern Yunnan, Western and Southern Sichuan, Southern Tibet, Western Sichuan, and Western Guangxi.
S. yunnanense are mainly distributed in Southwest China. Highly suitable habitats are distributed in Yunnan. Moderately suitable habitats are located at the border of Yunnan, Guizhou, and Sichuan. Poorly suitable habitats are distributed in Western Guizhou, Central Sichuan, Southern Shaanxi, Western Henan, Southern Fujian, Southern Tibet, and Western Guangxi.
The total suitable area for S. yannanense is more than that ofS. nepalense and S. ciliatum according to the mentioned climatic conditions (Table 1). These areas account for 9.35%, 6.43% and 3.39%, respectively, the total land area of china (960×104 km2) (Table 1). The highly suitable habitat area for S. ciliatum in the 2050s for SSP1-2.6, will be 9.92× 104 km2, the moderately suitable habitat area will be 11.39× 104km2, and the total habitat area will be 49.36× 104 km2. In the 2050s, for SSP5-8.5, the hilghly suitable habitat area for S. ciliatum’s will be 12.19× 104 km2, the moderately suitable habitat will be 12.02× 104km2, and the total area for habitat will be 51.83 × 104 km2. In the 2070s,for SSP1-2.6, the 9.74× 104 km2 area will be a highly suitable habitat for S. ciliatum species, the moderately suitable habitat will be 11.36× 104km2, and 48.1× 104km2 will be the total habitat area. In the 2070s, for SSP5-8.5, the highly suitable habitat area for S. ciliatum’s will be 21.94× 104 km2, the moderately suitable habitat is will be 15.34× 104km2, 69.46 × 104km2 will be the total area for habitat. The habitat which is more suitable will be found in Sichuan, Yunnan, Southern Tibet, and the border between Chongqing and Sichuan (Fig. 07).
The area of the highly appropriate habitat of S. nepalense in the 2050s for SSP1-2.6 will be 13.07 × 104km2, the area of moderately suitable habitat will be 18.53 × 104 km2, and the area of total habitat will be 76.42 × 104km2. In the 2050s, for SSP5-8.5, the area of S. nepalense highly appropriate habitat will be 11.95× 104 km2, the area of moderately suitable habitat will be 18.29× 104km2, and the area of total habitat will be 74.75 × 104 km2. The amount of highly appropriate habitat for S. nepalense in the 2070s for SSP1-2.6 will be 11.51× 104 km2, the area of moderately suitable habitat will be 18.98× 104km2, and the area of total habitat will be 75.15 × 104 km2. In the 2070s, for SSP5-8.5, the area of S. nepalense highly suitable habitat will be 16.60× 104 km2, the area of moderately suitable habitat will be 27.43× 104km2, and the area of total habitat will be 97.52 × 104 km2. It will mostly be located in Yunnan, Sichuan, Southern Tibet, and along the border between Sichuan and Chongqing (Fig. 7).
In the 2050s, for SSP1-2.6, the total highly suitable area for the habitat of S. yunnanense will be 20.91 × 104km2, 21.84 × 104km2 area will be moderately suitable habitat, and the total habitat area will be 123.31 × 104km2. In the 2050s, for SSP5-8.5, 18.25× 104 km2 area will be highly suitable for the habitat of S. yunnanense , the moderately suitable habitat area will be 24.31× 104km2, and the total habitat area will be 124.33 × 104km2 (Fig.07). In the 2070s, for SSP1-2.6, the area of highly appropriate habitat for S. yunnanense will be 19.58 × 104km2, the amount of moderately suitable habitat will be 23.60× 104km2, and the total habitat area will be 111.53× 104 km2. In the 2070s, for SSP5-8.5, the area of S. yunnanense highly appropriate habitat will be 25.12 × 104 km2, the area of moderately suitable habitat will be 31.79 × 104km2, and the area of total habitat will be 163.3 × 104 km2. The majority of the region will be in Yunnan, the middle of Sichuan, Southern Tibet, and the border between Sichuan and Chongqing (Fig. 7).
