The earliest year since 1951, the year of the dry period

Hubei Daily News (Reporter Liu Yesen) On August 12, the Yangtze River Committee held a conference to announce that the precipitation in the Yangtze River Basin in early August was more than 60 % of the same period, which was the least in the past 10 years. The year since the record of entering the dry period since the record of the year.

Affected by the continuous high temperature and rainy weather, the dry flow water level in the middle and lower reaches of the Yangtze River was significantly lower than that of the same period. Hubei, Hunan and other provinces (municipalities) have appeared to varying degrees of drought. Some provinces (municipalities) have initiated the corresponding level of drought resistance response. Beginning in mid -June, the precipitation of the Yangtze River Basin turned from more to less. Among them, in late June, less than 20 %, and less than 30 % in July, especially the dry flow of the lower reaches of the Yangtze River and the Poyang Lake Water system was about 50 %. Since July, the water from Hankou Station, Dongting Lake, and Wushuilai in the middle of the Yangtze River have been about 40 % less than the average value of the same period of many years. At 2:00 on August 6, the water level of Xingzi Station of Poyang Lake was retreated to 11.99 meters, and Poyang Lake entered the dry period in advance.

The reservoir group of the Yangtze River Basin is also greatly affected by drought. As of 8 o'clock on August 10, the upstream reservoir cluster of the Yangtze River was about 51.718 billion cubic meters of normal high water level. Among them, the Three Gorges Reservoir to be stored in the reservoir of 20.849 billion cubic meters, and the Danjiangkou Reservoir was to be stored in the reservoir 10.704 billion cubic meters. The average storage flow of the Three Gorges Reservoir was 16,000 cubic meters per second. For more than 40 % of the same period of the same period, the average entry flow of the Danjiangkou Reservoir was 757 cubic meters per second. At 8 o'clock on August 10th, the water level at the midstream and downstream of the two lakes and the export control station of the two lakes was 5-6 meters lower than the same period of the year. Three places, 2 in front of Hukou and Datong Station); Dongting Lake's four -water synthesis flow and Poyang Lake's Wuhe synthetic flow have been retreated to 2140 cubic meters per second and 1110 cubic meters per second.
