Abstract

This article examines the impact of the shrinking winter wheat sown area on agricultural water consumption in the Hebei Plain (China). The results are as follows. 1)The sown areas of winter wheat in the 11 cities in the Hebei Plain all shrunk during the study period, the most serious being in the Beijing-Tianjin-Tangshan metropolitan agglomerate. 2) The irrigation water resources demanded by the winter wheat-summer maize double cropping system ranged from 400 mm to 530 mm, while those demanded by the spring maize single cropping system ranged only from 160 mm to 210 mm. 3) The water resources conserved as a result of the winter wheat sown area shrinkage during the study period were about 15.96×108 m3/a, accounting for 27.85% of those provided for Beijing, Tianjin and Hebei by the first phase of the Mid-Route of the South-to-North Water Diversion Project
