我国农业用水量约占经济社会用水总量的62%,干旱半干旱地区比重更高。农田灌溉有效利用系数每提高0.1,就能节省300多亿立方米水,节水潜力巨大。大力推动干旱半干旱地区农业水资源高效利用,对于缓解当前水资源供需矛盾,发展生态友好型农业,保障国家粮食安全具有深远意义。一、农业高效节水工作成效显著
China’s agricultural water consumption accounts for about 62% of the total economic and social water use, with a higher proportion of arid and semi-arid areas. Every increase of 0.1% in the effective utilization coefficient of farmland irrigation can save over 30 billion cubic meters of water and has a great potential for water saving. Efforts to promote the efficient use of agricultural water resources in arid and semi-arid regions have far-reaching significance in alleviating the current contradiction between supply and demand of water resources, developing eco-friendly agriculture and ensuring national food security. First, the efficiency of water-saving agriculture has achieved remarkable results
