China's South-to-North Water Diversion middle route delivers over 80 billion cubic meters, benefiting nearly 118 million_我的网站

A |     (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)                    。    专题：精准营养产业大会 精准蛋白营养 赋能全生命周期健康 2026年8月21-23日，第二届精准营养产业大会在黑龙江哈尔滨举行，大会主题为“精准蛋白营养，赋能全生命周期健康”。中国工程院院士、中国检验检测学会会长、中国农业大学教授任发政在论坛上表示，蛋白质是生命的基础载体与核心执行者，广泛参与人体结构构建、物质代谢、免疫调节、物质运输等全部生命活动。而其最关键、最容易被忽视的核心特点，就是人体不存在蛋白质长期储备库。　　“人体每天都在进行大规模的蛋白质裁旧建新代谢过程，每日更新代谢量可达250克至300克，根据体重、代谢速率因人而异。”任发政解释，正因人体无法长期储存蛋白质，日常生命活动所需蛋白必须持续依靠膳食供给，这也直接决定了食物蛋白质的质量、结构与吸收效率，是维系人体生命活动的关键核心。　　任发政进一步结合人体代谢机制，阐释了精准蛋白营养的科学性与必要性。

B | 他介绍，人体蛋白质“裁旧建新”的循环过程中，60%至80%的氨基酸可被机体重复利用，但个体差异极大。

C | 不同人群的代谢速率、氨基酸重复利用率各不相同，部分人群利用率可达80%，部分仅为60%。

D | “利用率不同，人体所需外源食物蛋白、氨基酸的供给总量和种类就完全不同。”任发政强调，这一机制充分印证了蛋白质营养的时空性、个体性，也是精准营养、差异化膳食干预的核心生理学依据。　　谈及最新科研突破与产业升级方向，任发政表示，传统研究多聚焦蛋白质的氨基酸组成与消化吸收率，而当下前沿研究证实，蛋白质的功能活性不仅取决于氨基酸构成，更依赖其一级、二级、三级立体结构。

E | 最新研究发现，大量功能性蛋白可通过细胞膜内外直接转运吸收，为蛋白营养利用开辟了全新路径。　　对此，任发政指出，这一突破对食品加工工艺提出了全新要求。行业未来的核心攻关重点，是在食品加工全过程中最大化保留蛋白质原始结构与活性，实现高活性蛋白的高效提取、保留与精准输送，让功能性蛋白充分被人体吸收利用。

F | 在他看来，该方向是营养科学与食品工业融合创新的核心赛道。　　新浪声明：所有会议实录均为现场速记整理，未经演讲者审阅，新浪网登载此文出于传递更多信息之目的，并不意味着赞同其观点或证实其描述。责任编辑：李思阳。
