格拉沃利讷核电站是法国规模最大的核电站，配有6座反应堆，总装机容量5.4吉瓦，其发电量可满足上法兰西大区一年60%至70%的电力需求。据 《法兰西西部报》报道，8月10日深夜至11日清晨，3号、2号、4号和6号反应堆机组因水母堵塞关键设备，先后触发停机保护。而在此之前，1号 和5号反应堆本就处于夏季检修阶段。至此，该核电站6台机组全部停止运行。值得庆幸的是，此次事件未对核电站、人员或环境造成安全影响。 工作人员正进行紧急诊断和维修，以确保核电站安全重启。 法媒报道称，如此大规模的水母潮此前从未在核电站附近海域出现。这些水母大量聚集，堵塞了反应堆海水进水口的"过滤转鼓"，直接干扰了反 应堆冷却系统的正常运行。法国海洋开发研究院专家安塔让在接受法媒采访时表示，格拉沃利讷核电站的冷却系统从北海取水，而北海恰巧是多 种水母的栖息地。法国《回声报》进一步称，水母数量的激增与人类活动密切相关。一方面，过度捕捞行为减少了水母的天敌和竞争对手。另一 方面，全球变暖导致海水温度上升，为浮游生物增殖和水母繁殖创造了有利条件。 【环球时报驻法国特派记者 于超凡】当地时间8月11日，法国电力集团称，位于法国北部沿海地区的格拉沃利讷核 ...

Core Insights - The research team led by Professor Li Yu from Lanzhou University successfully reconstructed the dry-wet variation process in the upper Yellow River region during the Holocene, revealing the main mechanisms controlling these changes over a long time scale [1][3][4] Group 1: Research Findings - The study published in the journal "Science Bulletin" highlights significant regional differences in water resource evolution in China's northwest arid areas, with the western region gradually becoming "warmer and wetter" since the 1960s, while the eastern upper Yellow River area has continued to experience "aridification" [3][4] - The research team established a lake evolution research network in the Qilian Mountains and accurately characterized the Holocene dry-wet evolution, noting that lake water levels rose from the late Ice Age to the early Holocene, peaked during the mid-Holocene, and have been declining since the late Holocene [3][4] Group 2: Climate Mechanisms - The primary controlling factor for the Holocene dry-wet changes in the region is identified as the interaction between tropical ocean and atmosphere (ENSO), with observations indicating a recent trend of warming and wetting in the northwest, but a potential increase in ENSO amplitude could alter hydrological patterns and increase the risk of extreme drought events [3][4] - The study also simulated the water cycle of lakes in the East Asia-Central Asia arid region since the last glacial maximum, revealing differing water resource evolution patterns on the eastern and western sides, attributed to variations in moisture transport from monsoons and westerly winds, as well as differences in lake evaporation effects [4]
