解放以来,随着我国农田水利建设的蓬勃开展,我国的灌溉排水科学技术取得了很大进步,有力地促进了农田水利事业的发展。联合国粮农组织经过大量调查研究认为:灌溉农业对解决世界粮食问题至关重要,这一论断也基本符合我国的情况。我国人多地少,可垦荒地不多,降雨和水资源的时间空间分布不均,大部地区受旱涝灾害威胁。解放三十三年来,通过发展农田水利,抗旱除涝,有力地保证了农业产量的不断提高。今后,为在本世纪末实现工农业总产值翻两番的战略目标,大
Since liberation, with the vigorous development of farmland and water conservancy in our country, great progress has been made in science and technology of irrigation and drainage in our country, effectively promoting the development of farmland water conservancy. After a large number of UN Food and Agricultural Research Organization that: irrigation agriculture is crucial to solve the world’s food problems, this conclusion is basically consistent with our situation. There are few people in our country, few reclaimed land, and uneven distribution of rainfall and water resources in time and space. Most areas are threatened by droughts and floods. In the 33 years since the liberation, agricultural output has been effectively guaranteed through the development of farmland and water conservancy, drought relief and waterlogging. In the future, in order to achieve the strategic goal of quadrupling the gross industrial and agricultural output by the end of this century, it will be huge
