Spatial Distribution of Droughts

Figure 28.2 presents the spatial distribution of droughts from 1951 to 1991. In particular, four regions were identified where the frequency of drought was significantly high (Li and Lin, 1993): (1) Huanghuaihai region in the North China Plain, (2) Hebei, Shanxi, Shandong, Henan, and Shaanxi provinces, (3) the coastal south China, in particular the coastal area in Guangdong and Fujian provinces, and (4) the southwestern part of southwest China, mainly the southern part of Yunnan and Sichuan provinces. In addition, there is a narrow area in the western part of northeast China and arid regions in Gansu and Xinjiang in northwest China that are prone to drought (Li and Lin, 1993).
