河南是个人口大省,又是个农业大省,人均水量和亩均水量只相当全国的1/5和1/6,水资源严重不足。其中,农业用水占总量的很大比例。随着社会主义经济的发展,人民的生活质量不断提高,工业用水和生活用水量大大增加,水资源问题已经逐渐成为制约经济继续发展的重要问题。但是,我省农业灌溉用水量大,效率低下和溉灌用水浪费的问题仍普遍存在,使得原本就缺少的水资源更加匮乏。因此,实施节水灌溉战略已经迫在眉睫。 Henan is a big province with a large population. It is also a major agricultural province with a per-capita water amount and per-mu averaged only 1/5 and 1/6 of that of the entire country. There is a serious shortage of water resources. Among them, agricultural water accounts for a large proportion of the total. With the development of the socialist economy, people’s quality of life has been continuously improved, industrial water consumption and domestic water consumption have greatly increased, and the issue of water resources has gradually become an important issue that restricts the continuous economic development. However, the problems of large irrigation water use, low efficiency and waste of irrigated irrigation water are still widespread in our province, making the water resource scarcely lacking. Therefore, the implementation of water-saving irrigation strategy is imminent.
