Core Viewpoint - The Xiangjiaba ship lift has successfully transported over 10 million tons of cargo since its operation, significantly enhancing the shipping capacity and economic development of the Yangtze River basin [1][3]. Group 1: Operational Achievements - The Xiangjiaba ship lift, operational since May 2018, has completed over 23,900 trips and facilitated the passage of more than 23,000 vessels, with a maximum lifting height of 114.2 meters and a single lift capacity of approximately 8,150 tons [3][10]. - The annual cargo volume has increased from 170,000 tons to a peak of 1.95 million tons, with the time taken for vessels to pass through the lift reduced from 60 minutes to 40 minutes [5][11]. - The lift operates 24 hours a day, with a maximum of 339 operational days per year, extending the "golden waterway" of the Yangtze River by over 150 kilometers into the Jinsha River [5][7]. Group 2: Economic Impact - The ship lift has significantly improved shipping conditions in the reservoir area, providing a more efficient transportation channel for resource development and material transport, thus promoting coordinated economic development along the river [7][11]. - The logistics company reported that the lift allows larger vessels to load directly at the factory, increasing shipping frequency from two or three trips per month to five or six, greatly benefiting business operations [13]. Group 3: Technological Innovations - The Xiangjiaba ship lift is entirely designed and manufactured in China, marking a significant advancement in domestic engineering capabilities [8][10]. - Continuous technological innovations have led to the acquisition of 146 patents, enhancing the safety and efficiency of the lift's operations [11]. - The recent upgrades to the Xiangjiaba hydropower station's eight 800,000-kilowatt units have improved operational efficiency and reliability, incorporating smart online monitoring technologies [14][22].

Group 1 - The core viewpoint is that Sichuan's large reservoirs play a crucial role in the flood control system of the Yangtze River Basin, especially during periods of heavy rainfall [1][2] - Sichuan has over ten large reservoir power stations integrated into the unified flood control strategy of the Yangtze River Basin, highlighting its importance in regional flood management [2] - The Ministry of Water Resources has approved a plan to increase the number of water projects under unified dispatch from 127 to 132, including the newly added reservoirs in Sichuan [2] Group 2 - During the heavy rainfall from June 26 to July 1, 2024, the Ministry of Water Resources coordinated 53 control reservoirs in the upper and middle reaches of the Yangtze River, which collectively retained approximately 91 billion cubic meters of floodwater, significantly alleviating flood pressure in the lower reaches [3] - Currently, while the lower reaches of the Yangtze River are experiencing heavy rainfall, the dispatch of water projects is limited to key reservoirs in that area, with no orders issued for large reservoirs in Sichuan yet [4] - The Yangtze River Basin is in the plum rain season, which increases the risk of extreme rainfall and potential flooding in tributaries, necessitating careful management of water resources [4]
