自1949年到1979年的30年间,灌溉面积发展速度年均递增3.7％,粮食产量年均递增3.6％,全国人民的衣食得到了基本解决。据1985年统计,河北省灌溉面积为0.53亿亩,比建国时期增长了4倍,粮食总产量增长3.2倍,棉花总产量增长4.8倍,油料总产量增长1.3倍。这些都说明了农田灌溉事业的发展,对提高农作物的产量是显著的。但是,河北省是我国水资源较少的省分之一,人均和亩均占有水量均低于全国平均水平。
During the 30 years from 1949 to 1979, the average annual growth rate of irrigated area increased by 3.7% and the average annual grain output increased by 3.6%. The basic food and clothing of the people in the country was basically solved. According to the statistics of 1985, the irrigated area in Hebei Province was 0.53 billion mu, an increase of 4 times that of the founding of the People’s Republic of China. The total grain output increased by 3.2 times, the total cotton output increased by 4.8 times and the total oil output increased by 1.3 times. All these illustrate the development of irrigation in farmland and are significant to increase the yield of crops. However, Hebei Province is one of the provinces with a small amount of water resources in our country. The water amount per capita and mu is below the national average.
