农业节水灌溉现状及发展趋势

Status and Development Trend of Agricultural Water Saving Irrigation

我国农村用水存在水资源紧缺与水资源污染、浪费严重的突出矛盾，水分利用率仅为30％～40％；节水灌溉设备存在很大差距，管理体系有待进一步完善。为了解决该问题，应该更新理念，研究领域围绕现代农业的发展，不断向节水、高效和环保的领域扩展。采取加大工程设施建设力度、加强灌水设备和量水设备的研制与开发、加强作物需水规律和灌溉制度的研究、加强农田水利应用基础研究等措施，解决农业水资源短缺，保证农业、水利可持续发展。

There is conspicuous contradiction between water shortage and seious water resource pollution and waste in Chinese rural area. The water use efficiency is only 30% - 40% , the water saving irrigation equipment has very big disparity, and the management system needs further perfect. The idea should be renewed, and the research field should be extended around the development of modern agriculture. The measures should be taken including strengthening the dynamics of engineering facilities construction, the research and development of irrigation and water measure equipments, the researches on water requirement rules and irrigation systems of crops, and the basic research on the application of farmland water conservancy to sovle the problems of water resource shortage and ensure the sustainable development of agriculture and water conservancy.
