一 |     香山股份：首次回购43万股 每经AI快讯，香山股份（SZ002870，收盘价：46.85元）8月26日晚间发布公告称，2026年8月26日，公司首次通过股份回购专用证券账户以集中竞价方式回购公司股份43万股，回购总金额约为2038万元，回购股份占公司目前总股本的0.28%，最高成交价为48元/股，最低成交价为46.92元/股。    (ECNS) -- The first phase of the middle route of China's South-to-North Water Diversion Project had transferred more than 80 billion cubic meters of water to northern China as of Friday, directly benefiting nearly 118 million people, according to the Changjiang Water Resources Commission.     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.     (By Helen Mo, intern Yang Hongran)                    。    每经头条（nbdtoutiao）——井柏然、高圆圆闯进曾经的“工业锈带”！上百万游客也去了，当地文旅成立工作组专门服务“七郎”！一个地方小镇如何带来转型样本？     （记者王瀚黎）     免责声明：本文内容与数据仅供参考，不构成投资建议，使用前请核实。据此操作，风险自担。    每日经济新闻     。
