央视网消息：记者从水利部了解到，24日，三峡水库完成2025年175米蓄水目标，有效蓄水量可达221.5亿立方米，这是三峡水库自2010年 首次蓄至175米后第14次实现蓄满目标，为今冬明春充分发挥供水、生态、发电、航运等综合效益奠定了坚实基础。 三峡水库完成2025年175米蓄水目标：175米最高水位意味着什么？ 175米是三峡水库正常运用可以达到的最高水位，也是三峡水库为长江中下游防洪可以调度运用的最高水位。三峡水库为什么要蓄水到175 米？这个数字究竟意味着什么呢？ 175米是三峡水库在每年汛期结束时需要"存满水"的一个标准刻度。只有达到这个高度，三峡水库才能在接下来的枯水期里有足够的水资 源平稳下放。 纳入联合调度的长江流域共有58座控制性水库。然而，蓄水绝非简单的关闸蓄水，而是一场"蓄"与"泄"的精准博弈。 长江流域宜昌水文站的历史数据显示，每年超过60%的来水量都集中在汛期，而到了冬季枯水期，来水量却常常捉襟见肘。所以三峡水库 必须在10月底存蓄足够的水，才能在枯水期均匀地释放给中下游。据统计，从去年11月—今年4月期间，三峡水库就累计向下游补水116.7亿立 方米，相当于为超过1500万人储备了 ...
