Introduce the great river defense of 1998.

1998 After the catastrophic flood in the Yangtze River basin, the China municipal government strengthened the infrastructure construction, and the perfect flood control system enabled the Yangtze River levee to successfully resist this year's flood. Since the beginning of this year, the largest flood peak of the Yangtze River has successfully entered the sea on August 3 1. The flood control work in China has achieved initial results.

According to international online news, since August 19 this year, the water level of Dongting Lake, the largest river in China, has been rising all the way due to the continuous rainstorm in the upper reaches of the Yangtze River, until it reached the highest water level of 34.9 1 m this year on the 24th, nearly 3 meters higher than the warning water level. However, under the effective protection of flood control facilities and the protection of hundreds of thousands of soldiers and civilians, there is no danger in the Yangtze River dike in Hunan Province and no dam break in Dongting Lake.

Zhang, deputy director of Hunan Provincial Water Resources Department, participated in the flood fighting and emergency rescue work in the Yangtze River Basin of China from 65438 to 0998. He said that at that time, there were seven dikes in the province. Since then, the central government and the Hunan provincial government have intensified the construction of water conservancy projects. He said: "We should fully affirm the proactive fiscal policy implemented by our country since 1998, increase investment in water conservancy and build a large number of flood control projects. The whole flood control system was fully improved and strengthened after the 98 flood. This is the basis for us to overcome the flood.

According to reports, in recent years, Hunan Province has invested 20 billion yuan in construction, of which 65.438+0.37 billion yuan has been used to reinforce the 65.438+0.42-kilometer-long trunk dike of the Yangtze River, and more than 4 billion yuan has been used for key dikes and related water conservancy construction in Dongting Lake.

In the water conservancy construction work, Hunan Province has also implemented a project called "Leveling embankments to flood, and resettling people to build towns", that is, removing some embankments as flood channels; Farmers in low-lying areas will be moved to safe places and new towns will be established. According to reports, from 1998 to now, Hunan Province has relocated120,000 households with more than 420,000 people. The project has enlarged the water storage area of Dongting Lake, increased the water storage capacity and reduced the flood control pressure of Dongting Lake dam.

When the Yangtze River flows through Jingzhou, Hubei Province, the 430-kilometer-long main channel narrows and the river turns several times, so Jingzhou has always been a place with serious floods in history. During the period of 1998, there was a big flood in the whole Yangtze River basin, and the Yangtze River embankment in Jingzhou City was always in danger. Jingzhou Yangtze River levee mobilized nearly 40? %
