The water comes mainly from Danjiangkou Reservoir, where managers balance reservoir inflows, local demand in the Hanjiang River basin, northbound supplies, and downstream ecological needs. This summer, after forecasts pointed to below-normal rainfall, authorities adjusted reservoir operations to retain about 1.5 billion cubic meters more water as a buffer against possible drought. Technology is playing a growing role in monitoring water quality. An AI-powered floating platform works alongside satellites, drones, and ground monitoring stations, feeding data into a digital twin of Danjiangkou Reservoir that tracks water quality, simulates flood scenarios, and supports emergency planning. At Danjiangkou Reservoir, the core water source for the middle route, an autonomous vessel collects samples from different depths to monitor algae. Using AI-powered microscopy, the floating station identifies microorganisms quickly and tracks algal activity, giving early warning of blooms. The vessel is part of an integrated satellite, aerial, surface, and structural monitoring network that combines remote sensing, drones, ground-based stations, and sensors embedded in the dam. By fusing multi-source data in real time, the system has shifted water monitoring "from isolated points to full-area coverage," said Cui Dongdong, deputy director of the technology development department at a company under the Yangtze River Water Resources Commission of the Ministry of Water Resources. With the digital platform, a regulation plan that once took days to produce can now be generated in seconds. The platform runs more than 15 professional models covering flood routing, pollutant dispersion, and dam structure simulation. The 1,432-kilometer middle route canal carries water across the Yangtze, Huai, Yellow, and Hai river basins before it reaches households in the north. Water quality has also improved, and the nationally protected "crystal jellyfish," known as the "giant panda of the water," is now sighted frequently in the reservoir, an indicator of excellent conditions.

。 2025年8月13日,应中国单模光纤产业申请,商务部发布2025年第42号公告,决定自2025年8月14日起,对原产于印度的进口单模光纤所适用的反倾销措施进行期终复审调查。

B | 商务部裁定,如果终止反倾销措施,原产于印度的进口单模光纤对中国的倾销可能继续或再度发生,对中国单模光纤产业造成的损害可能继续或再度发生。 根据《中华人民共和国反倾销条例》有关规定,商务部根据调查结果向国务院关税税则委员会提出继续实施反倾销措施的建议。国务院关税税则委员会根据商务部的建议作出决定,自2026年8月14日起,对原产于印度的进口单模光纤继续征收反倾销税,实施期限为5年。

C | 据悉,单模光纤主要应用于高速率、长距离以及接入网传输,主要使用在长途干线、城域网、有线电视、光纤接入网(如FTTH)等网络。
