Recently, Poyang Lake—the largest freshwater lake in China—has seen its water level drop below the historically recorded extreme low mark. According to data from Jiangxi Province’s hydrological monitoring authorities, the water level at the Xingzi station fell below 7.1 meters, significantly lower than the historical average for this time of year and marking the lowest level since comprehensive records began in 1951. The primary causes include drastically reduced inflow from the upper reaches of the Yangtze River, below-average local rainfall in Jiangxi, and intensified evaporation due to prolonged high temperatures. As a crucial flood-buffering reservoir and ecological barrier in the Yangtze River Basin, Poyang Lake’s critically low water levels threaten drinking water supplies and agricultural irrigation for millions of residents, while also endangering habitats for migratory birds, fish migration routes, and the broader wetland ecosystem. Experts are urging enhanced coordinated water resource management across the basin, improved drought-response capabilities, and long-term ecological conservation strategies to address increasingly frequent extreme hydrological events driven by climate change.
近日，中国最大淡水湖——鄱阳湖水位持续下降，已跌破有记录以来的极枯水位。据江西省水文监测部门数据显示，鄱阳湖星子站水位一度降至7.1米以下，远低于历史同期平均水平，创下自1951年有完整水文记录以来的最低值。造成此次极端枯水的主要原因包括：长江上游来水显著减少、江西本地降水偏少以及持续高温导致蒸发加剧。鄱阳湖作为长江流域重要的调蓄湖泊和生态屏障，其水位异常不仅影响湖区数百万居民的饮水安全和农业灌溉，还对候鸟栖息地、鱼类洄游通道及湿地生态系统构成严重威胁。专家呼吁加强流域水资源统筹调度，提升抗旱应急能力，并推动长期生态保护措施，以应对气候变化背景下日益频发的极端水文事件。
