节水灌溉无论对于国家的水资源还是对农业发展都有着非常重要的意义。从节水灌溉角度来说,其自身的重要意义是多个方面的;对于农业生产来说,节水灌溉技术能够发挥水资源的最大化价值;对于国家的可持续发展来说,水资源紧缺的现状需要从各个角度寻求节约用水的途径。而农业灌溉作为占据水资源用量较大比例的用水方式,节水功能的发挥对我国水资源的节约利用有着非常显著的作用。基于此,首先分析广西桂林地区的节水灌溉现状及其中存在的问题,然后明确节水灌溉对我国农业可持续发展的意义,最后从节水灌溉的技术角度对节水提升途径做出全面分析,以期促进我国农业可持续发展。
Water-saving irrigation is very important for both national water resources and agricultural development. From the perspective of water-saving irrigation, its own significance is multifaceted; for agricultural production, water-saving irrigation technology can maximize the value of water resources; for the sustainable development of the country, the water shortage The status quo needs to seek ways to save water from all angles. As agricultural irrigation takes up a larger proportion of water resources, the water-saving function plays a very significant role in saving and using water resources in our country. Based on this, we first analyze the present situation of water-saving irrigation in Guilin, Guangxi and its existing problems, and then clarify the significance of water-saving irrigation on the sustainable development of agriculture in China. Finally, we make a comprehensive analysis of water-saving promotion from the technical point of water-saving irrigation , With a view to promoting the sustainable development of agriculture in our country.
