新疆滴灌节水30年的成就、挑战与发展思考OA

Xinjiang,as the core area of drought and water shortage in China,faces water scarcity that is a key bottleneck restricting the sustainable development of its agriculture.After 30 years of technological innovation in drip irrigation and its large-scale promotion,Xinjiang has established the world's largest drip-irrigated area.The breakthrough application of mulched drip irrigation has promoted revolutionary changes in regional agricultural water saving and agricultural development.This paper systematically summarized the achievements of water-saving drip irrigation in Xinjiang over the past 30 years,including improving food security and agricultural product supply capacity,promoting regional sustainable agricultural development and ecological environment improvement,facilitating intensive and efficient agricultural development and modernization,and accelerating technological innovation and industrial development in agricultural water saving.It also analyzed the gap between Xinjiang's current drip irrigation water-saving practices and the world's advanced level,as well as the main problems and challenges in reducing evaporation and water loss in water-saving projects,energy conservation and emission reduction,research and development of water-saving equipment and key technological breakthroughs,and project management and market supervision of water-saving irrigation.Furthermore,the paper put forward reflections and suggestions for promoting the high-quality development of drip irrigation water-saving in Xinjiang.These include promoting the upgrading of water-saving and efficiency-increasing agriculture within the framework of"three high goals,five new requirements,six highlands,seven systems,and nine projects";promoting the construction of an upgraded"Karez"project for the new era according to local conditions;achieving breakthroughs in common and key technologies for future drip irrigation water-saving,and comprehensively fostering the sound development of drip irrigation water-saving projects and industries.The aim is to provide a reference for building Xinjiang into a world-class new highland for agricultural water-saving and efficiency enhancement.
