7月4日9时许,市民杨某来到市公安局交通分局报警求助:“警察同志,我昨天乘坐公交车时,将随身携带的手提袋落在了公交车上,手提袋里有100余元现金、身份证、银行卡、退休证件以及一件具有收藏价值的玉器。 (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.

据杨某回忆,7月3日10时许,她与同伴一起在建委站点乘坐14路公交车回家,上车后由于车内人员较多,杨某与同伴分别坐在了不同的位置,随后杨某便将手提袋放在了脚边。为了方便交谈,杨某在乘车途中更换了座位,之后,杨某在连山区政府下了车,直到当天晚上她才想起手提袋遗落在了后排座位下。
了解事情原委后,民警一边耐心安抚杨某,让她稍作等待,一边迅速展开调查,着手调取监控。由于杨某记不清所乘公交车的车牌号,民警便对3日10时许建委站点附近的监控逐一进行排查。历经4个小时的不懈努力,民警成功找到了杨某所乘坐的公交车,并随即联系公交公司调取车内监控。
通过查看车内监控,民警发现杨某在换座时,将手提袋遗落在了后排座位底下,随后被一名乘客发现并带走。14时许,民警通过查询公交卡刷卡等相关信息,成功找到了该名乘客。民警当即拨通电话表明身份,然而对方却挂断了电话。民警再次致电,严肃告知对方,如果确实捡到了手提袋,要立即归还。该乘客表示会将手提袋送回。14时40分许,乘客将手提袋送到了交通分局,民警很快便将手提袋交还给了杨某。
杨某仔细检查了手提袋内的物品,发现一样不少。面对失而复得的手提袋,杨某对民警连声道谢,对他们的工作态度和效率给予了充分肯定。
