Qujiang River is the largest tributary on the left bank of Jialing River. During the "9. 18" rainstorm and flood in 20 1 year, the largest flood occurred in Qujiang basin in history. Looking back at history, Qujiang was once one of the fiercest floods in the upper reaches of the Yangtze River.
"In the past 10 years, there was no major flood in Qujiang River Basin." The relevant person in charge of Sichuan Flood Control and Drought Relief Headquarters said that although it was "God's will", the fundamental reason was that Sichuan had made many explorations in flood control mechanism and engineering construction in 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 the upstream and downstream and unify the pace. In order to break the "framework" of administrative divisions that limit the overall dispatching capacity of Qujiang River Basin in flood season, the provincial government decided to set up Qujiang River Basin Flood Control Headquarters (referred to as Qujiang Flood Control Headquarters) in September, 2065438+2004, and the daily work was undertaken by Dazhou City.
"If flood control is judged and deployed early, it is necessary to make a good move of flood control and waterlogging control." According to the relevant person in charge of Qujiang finger defense, before the flood season this year, the commander-in-chief of Qujiang finger defense called 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, the relevant leaders of Sichuan Water Resources Department and flood control experts 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 the flood control of Qujiang River.
In addition, relying on Dazhou Meteorological Bureau, Qujiang prevention and control center was established, which 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 control emergency rescue schemes and flood control plans of large reservoir projects such as Huangshipan in Bazhong in the upper reaches of Qujiang River, which enhanced the practicability of the plans.
Heizai New Protocol: Strengthening the Horizontal and Vertical Linkage Response
"Every time we receive an early warning and transfer order, we take action to fight the flood." Zhou is the village party secretary of Lijiadu, Panshi Town, Tongchuan District, Dazhou City. His other identity is the "early warning transfer team leader" of Lijiadu on the Yue Ming River in Dazhou 139 1 mountain flood danger zone.
On August 22nd this year, there were 15 rivers in Dazhou, all above the warning water level, and the water level of Yueming River changed by 4. 19 meters. "The flood has risen rapidly, so it must be evacuated quickly." Zhou also gave feedback to the flood control headquarters at any time on the disaster situation 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 flood control in Qujiang refers to the formulation of flood control consultation, flood transmission and flood control dispatching systems. Qujiang refers to the establishment of a joint prevention and control mechanism for cross-border rivers. The three places exchange early warning information, * * * enjoy the local actual rain and water information, and also form emergency communication and linkage to eliminate dangerous situations.
Affected by heavy rainfall, it is expected that the main stream of Qujiang River and some tributaries will have floods close to or exceeding the warning water level, and the main streams 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 suffered several rounds of heavy rainfall days, and the disaster situation in the early stage was serious, which 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 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.
