河北省是个淡水资源极度匮乏的省份,人均淡水占有量居全国倒数第一。近十年来,由于持续干旱,造成地上水源枯竭,地下水位下降,干旱十分严重。随着工农业生产的发展,农业用水量急剧增加,已占到总用水量的80%左右,一些地区农业生产粗放,仍在采用大水漫灌的浇地方法,导致水资源的严重浪费。因此,发展节水农业,大力推广综合节水技术势在必行。 Hebei Province is a province where freshwater resources are extremely scarce. Freshwater reserves per capita ranks the first in the country. In the past decade, the droughts have been very serious due to the continuous droughts that have caused the depletion of groundwater resources and the decrease of groundwater table. With the development of industry and agriculture, the water consumption of agriculture has increased sharply, accounting for about 80% of the total water consumption. In some areas, extensive agricultural production is still using irrigated land for flood irrigation, resulting in serious waste of water resources. Therefore, it is imperative to develop water-saving agriculture and vigorously promote integrated water-saving technologies.
