Xuzhou-Huai plain

The Xuzhou-Huai plain is an alluvial plain in northern Jiangsu province, China, formed by the deposits of the Huai and Yellow rivers. This region stands about 30 to 150 feet (9 to 45 meters) above sea level and includes low hills in its northern part. It is part of the larger North China Plain.1

Historically, this area has been a significant transportation and strategic point due to its location in a gap within the Shandong Hills, which connects waterways like the Grand Canal to the Yangtze River. The region has experienced significant historical events, including battles during the Sino-Japanese War and the Chinese Civil War.2

The climate in the northern part of this plain follows a cool, temperate continental pattern with greater temperature extremes, distinct seasons, and annual precipitation ranging from 32 to 47 inches (800 to 1,200 mm).3
