“…The YREB encompasses nine provinces and two municipalities, covering approximately 205.23 × 10 4 km 2 , and accounting for 21.38% of the total area of China. The YREB can be divided into three subregions: the eastern subregion (i.e., the downstream subregion), which includes Shanghai, Jiangsu, Zhejiang, and Anhui provinces; the central subregion (i.e., the midstream subregion), which includes Jiangxi, Hubei, and Hunan provinces; and the western subregion (i.e., the upstream subregion), which includes Chongqing, Sichuan, Guizhou, and Yunnan provinces (Jin et al, 2018; Yang, Han, et al, 2022). Correspondingly, 11 provincial cities in the YREB were investigated, including Shanghai, Nanjing, Jiangsu, Hangzhou, Zhejiang, Hefei, Anhui, Nanchang, Jiangxi, Wuhan, Hubei, Changsha, Hunan, Chongqing, Chengdu, Sichuan, Kunming, Yunnan, and Guiyang, Guizhou (Figure 1).…”
