Qujiang River is the largest tributary on the left bank of Jialing River. In the "September 18" rainstorm and flood in 211, the biggest flood occurred in Qujiang River basin in history. Looking back at history, Qujiang River was once one of the fiercest floods in the upper reaches of the Yangtze River.
"In the past 1 years, there has been no major flood in Qujiang River Basin." The relevant person in charge of the Sichuan Flood Control and Drought Relief Headquarters said that although "God is willing", the root cause is that Sichuan has made many explorations in the flood control mechanism and engineering construction in the Qujiang River Basin.
Qujiang River Basin involves Bazhong, Dazhou, Guang 'an and other cities. To defeat the "flood monster", the winning strategy is to unite upstream and downstream and unify the pace. In order to break the administrative division "frame" that restricts the overall dispatching capacity of Qujiang River Basin in flood season, in September 214, the provincial government decided to set up the flood control headquarters of Qujiang River Basin (referred to as Qujiang Flood Control Index), and Dazhou City will undertake the daily work.
"If flood control is judged early and deployed early, we must play a good game of' prevention' and' treatment' of flood disasters." According to the relevant person in charge of Qujiang finger defense, before the flood season this year, the commander of Qujiang finger defense convened the deputy commanders and member units of Bazhong, Dazhou and Guang 'an to hold a meeting of Qujiang finger defense members to study and deploy flood control and disaster reduction work. At the same time, relevant leaders and flood control experts from Sichuan Provincial Water Resources Department were invited to conduct advanced research and on-site guidance on the climate characteristics and flood control situation of Qujiang River Basin, which provided strong technical support for winning flood control in Qujiang River.
In addition, relying on Dazhou Meteorological Bureau, the Qujiang River Prevention and Control Center has been established, which has improved the monitoring and early warning ability of rainwater conditions in the basin. At the same time, experts were organized to review and give technical guidance on flood prevention and rescue plans and flood control schemes for large reservoir projects such as Huangshipan in Bazhong in the upper reaches of Qujiang River, which enhanced the practicality of the plans.
Killer 2: Strengthen the horizontal and vertical linkage response
"Every time we receive an early warning and a transfer order, we will take action to fight against the flood." Zhou Shunli is the village party secretary of Lijiadu, Panshi Town, Tongchuan District, Dazhou City. His other identity is the "early warning transfer person in charge" of Lijiadu on the Mingyue River among the 1391 dangerous areas of mountain torrents in Dazhou.
On August 22nd this year, 15 rivers in Dazhou experienced flood, all above the warning water level, and the water level of Mingyue River varied by 4.19 meters. "The flood is rising very fast and must be evacuated quickly." Zhou Shunli also gave feedback to the flood control headquarters at any time on the scene of the disaster and the transfer of people.
according to the principle of "unified command, hierarchical dispatching and hierarchical management", the whole basin is regarded as "a chess game", and the Qujiang River flood control refers to the formulation of flood control consultation, flood control transmission and flood control dispatching system. Qujiang River defense refers to the establishment of a joint prevention and control mechanism for cross-border rivers. The three places exchange early warning information, * * * enjoy local information such as actual rain and water conditions, and also form emergency communication and linkage to eliminate dangers.
under the influence of heavy rainfall, it is predicted that the main stream of Qujiang River and some tributaries will have floods close to or exceeding the warning water level, and the main stream of Fujiang River and Jialing River will have a small water rising process, and some tributaries will have floods close to or exceeding the warning water level.
since the flood season this year, Qujiang river basin in northeast Sichuan has been hit by several rounds of heavy rainfall days, which has caused serious disasters in the early stage, and has become one of the key basins for flood control and disaster reduction in our province this year. In this regard, the relevant person in charge of the Provincial Water Resources Department said that the northeast and northwest of the basin are the main areas of this round of rainfall, and some problems found in the previous damaged water conservancy and flood control projects and major investigations are being rectified. In some areas, the soil is saturated, and the bottom water of small and medium-sized reservoirs and small and medium-sized rivers is high, which is easy to cause floods. We must pay close attention to key parts and do a good job in defense and protection.
