水利是农业的命脉,水事关乎民,水事大于天。新中国成立以来,我国水利建设取得了巨大的成就,江河防洪能力不断提升,农田水利设施不断完善,农田水利保障能力大幅度增强,为我国经济社会发展和社会主义现代化建设提供了重要的支撑和保障。农田灌溉呈现“最后一公里”问题,基层水利服务体系薄弱,将会成为农业农村经济社会发展的突出制约因素。农田水利建设滞后影响国家粮食安全;农业用水资源利用率不高,制约现代农业建设。 Water conservancy is the lifeblood of agriculture, water matters to people, water is greater than the sky. Since the founding of New China, great achievements have been made in the construction of water conservancy in our country. The ability of preventing floods in rivers and rivers has been constantly improved. The facilities for irrigation and water conservancy in farmlands have been continuously improved and the ability to support irrigation and water conservancy has been greatly enhanced. This has provided important support for China’s economic and social development and socialist modernization. Protection. Farmland irrigation shows “the last mile ” problem, grass-roots water conservancy service system is weak, will become the agricultural and rural economic and social development of the prominent constraints. Lack of farmland water conservancy construction affects the national food security; the utilization rate of agricultural water resources is not high, restricting the construction of modern agriculture.
