本刊讯2月中旬以来,黄河下游两岸地区冬小麦开始返青并快速生长,河南、山东引黄灌区陆续开始引黄灌溉,逐渐进入春灌用水高峰期。为满足黄河下游春灌用水需求,黄委及时调整水量调度方案,3月1日,调整小浪底水库下泄流量由500 m~3/s增大至800 m~3/s。据了解,受厄尔尼诺现象影响,黄河流域自2015年汛期以来来水持续偏少,较常年偏少4成以上。黄河干流龙羊峡、刘家峡、万家寨、三门峡、小浪底五大水库合计蓄水量为243.33亿m~3,比2014年同期少67.8亿m~3,比
Since mid-February, winter wheat in the lower reaches of the Yellow River has started to rejuvenate and grow rapidly. Yellow and yellow irrigation areas in Henan and Shandong have started to divert irrigation from the Yellow River to the spring irrigation water peak. To meet the demand for spring irrigation water in the lower reaches of the Yellow River, the Yellow River Commission timely adjusted the water regulation plan. On March 1, the discharge flow of Xiaolangdi Reservoir was adjusted from 500 m 3 / s to 800 m 3 / s. It is understood that, due to the El Niño phenomenon, inflows of water in the Yellow River Basin continued to be somewhat below normal since the flood season in 2015, a decrease of more than 4% from the previous year. The total reservoirs of Longyangxia, Liujiaxia, Wanjiazhai, Sanmenxia and Xiaolangdi Rivers in the Yellow River totaled 24.333 billion m 3, a decrease of 6.78 billion m 3 from the same period of 2014
