Changchiang Plain

Ch’angchiang Plain


an alluvial plain in the basin of the lower Yangtze River and one of its tributaries, the Han Shui, in China. The Ch’angchiang Plain has an area of approximately 100,000 sq km. Its surface is flat but becomes hilly on the margins. The plain is crossed by numerous rivers and canals, and it is swampy in places. Its many lakes include Tungt’ing Hu. During the summer high water, the rivers occasionally flood; major floods occurred in 1931 and 1954. As a protective measure, the river banks have been lined with dikes. The plain is one of China’s major rice-growing regions, and wheat, corn, and cotton are cultivated. The Ch’angchiang Plain is densely populated and includes the large city of Wuhan.
