摘要

The biggest load of water resources for agricultural economy in the Huang-Hai plain will only account for 67.1/100 of the forecasted irrigated area in 2010. The irrigated area and the quantily of water diverting from the Huanghe River was 2.2 million hm~2 and 10.8 billion m~3 respectively in the lower reaches of the river in the 1990s. The annual amount of yield increase for grain is 6.3 billion kg calculated by converting and the annual benefit of yield-increase is 4.4 billion RMB yuan in the irrigated area of the region.
