黄河灌区年超量引黄河水18.72亿m~3是造成黄河断流的重要因素之一。河套灌区节水措施及节水潜力主要有渠道衬砌年可节水22亿m~3,改进灌水方式节水10％,建设节水型农田防护林年可节水1.47亿m~3,重复利用总排干沟回归水年可节水3亿m~3。
In the Yellow River Irrigation Area, an annual excess of 1.872 billion m 3 of Yellow River water is one of the important factors that cause the Yellow River to shut off the Yellow River. The water saving measures and water saving potential of Hetao Irrigation District are mainly water-saving 2.2 billion m 3 per year, water saving 10% by improving irrigation methods and saving 147 million m 3 water-saving farmland shelterbelt. The total recycling Drainage channel to return to water years can save 300 million m ~ 3.
