长江2020年第3号洪水形成 水利部细化实化应对措施-中新网 新华社北京7月26日电(记者胡璐)26日，长江2020年第3号洪水形成。 水利部部长鄂竟平26日在主持会商时要求，精细调度三峡水库，统筹考虑长江上游及洞庭湖来水，实施错峰调度，留足库容准备迎战还有可能出现的大洪水，并确保中下游干流和洞庭湖重要堤防的防洪安全。 据预报，未来3天西南东部、江淮南部、江南北部西部及湖北东部南部、广西中部等地部分地区将有大到暴雨，其中湖南北部、江苏西南部等地局部将有大雨；华北中部西部等地将有中到大雨，其中河北中部局部将有暴雨。 水利部预计，受其影响，长江上游三峡水库28日前后入库流量可能达到60000立方米每秒左右，中游干流莲花塘江段及洞庭湖水位复涨并超保0.20米左右；淮河中游干流水位总体缓退，洪泽湖水位继续缓涨；海河大清河水系、永定河等河流将出现涨水过程。 鄂竟平提出，淮河流域要进一步加大洪水排泄力度，尽快降低洪泽湖水位，准备迎战还有可能出现的大洪水。 要充分做好沂沭泗水系暴雨洪水应对工作。 他说，太湖流域要毫不松懈继续加大洪水外排力度，尽快降低太湖及周边河网水位，减少太湖高水位与台风遭遇的风险。 此外，他强调，内蒙古、河北等北方地区洪水陡涨陡落，预警时间短，极易造成山洪泥石流灾害，防御难度大；中小水库和淤地坝数量多，存在安全隐患。
The No.3 flood of the Yangtze River in 2020 was formed. The Ministry of Water Resources has refined and implemented countermeasures - www.chinanews.com Xinhua News Agency, Beijing, July 26 (Reporter Hu Lu) - On the 26th, the No.3 flood of the Yangtze River in 2020 was formed. On 26th, E Jingping, Minister of the Ministry of Water Resource, presided over the meeting, demanding that the Three Gorges Reservoir should be carefully dispatched, the water coming from the upper reaches of the Yangtze River and Dongting Lake should be taken into account as a whole, the staggered peak dispatching should be implemented, the storage capacity of reservoirs should be reserved to prepare for possible major floods, and the flood control safety of the main stream of the middle and lower reaches and the important dikes of Dongting Lake should be ensured. It is predicted that there will be heavy-hard rain in parts of southwestern China, southern Jianghuai, northern and western Jiangnan, eastern and southern Hubei, and central Guangxi in the next three days, including heavy rain in northern Hunan and southwestern Jiangsu; and there will be moderate- heavy rain in the central and western parts of North China, including heavy rain in some parts of central Hebei. The Ministry of Water Resources predicts that due to the impact of heavy rain, the rain inflow of the Three Gorges Reservoir in the upper reaches of the Yangtze River may reach about 60,000 cubic meters per second around the 28th, and the water level of the Lianhuatang River section and Dongting Lake in the middle reaches will rise again and exceed 0.20 meters; the water level of the main stream in the middle reaches of Huaihe River generally slows down, and the water level of Hongze Lake continues to rise slowly; and Haihe River Daqinghe River system, Yongding River and other rivers will have a rising water process. E Jingping proposed that the Huaihe River Basin should further intensify flood discharge, lower the water level of Hongze Lake as soon as possible, and prepare for the possible flood. It is necessary to do a good job in dealing with the storms and floods in Yishu-Sishui system. He said that the Taihu Lake Basin should continue to increase flood discharge without slackening, reduce the water level of Taihu Lake and its surrounding river network as soon as possible, and reduce the risk of high water level and typhoon in Taihu Lake. In addition, he emphasized that floods in northern areas such as Inner Mongolia and Hebei rose and fell sharply, and the warning time was short, which is easy to cause flash floods and mudslides, and it was difficult to defend; and there were many small and medium-sized reservoirs and warping dams, which have potential safety hazards.
