缓解东苕溪流域防汛压力 余杭北湖滞洪区6闸全开分洪_我的网站

A |     (ECNS) -- China remained Germany’s largest trading partner in the first half of 2026, with bilateral trade reaching 125.5 billion euros ($146.8 billion), according to data released by the German Federal Statistical Office on Wednesday.    China was Germany’s largest trading partner for eight consecutive years from 2016 to 2023. The United States overtook China in 2024, before China regained the top position in 2025.    In the first half of 2026, the United States ranked second among Germany’s trading partners, with bilateral trade totaling 123.7 billion euros, followed by the Netherlands at 109.3 billion euros.                        。    受台风“白海豚”影响，苕溪流域出现2026年第1号洪水。8月10日8时30分，余杭启用北湖滞洪区，北湖分洪闸6个闸门全部开启，通过分洪削峰，缓解东苕溪流域严峻防洪压力，保障区域防洪安全。据悉，本轮台风导致苕溪流域累计降雨量达206.7毫米，持续强降雨引发河道水位暴涨。8月10日1时40分，瓶窑站水位达5.66米，达到洪水编号标准，且预报后续仍有集中降雨，河道水位将持续攀升，防汛形势严峻。余杭区地形复杂，东苕溪河道源短流急，极易引起水位暴涨暴落。西险大塘位于东苕溪右岸，是杭州西北部重要防洪屏障，也是守护杭嘉湖平原的最后一道防线。北湖滞洪区位于瓶窑镇张堰村，地处三苕溪汇流三角地带，总面积5.3平方公里，滞洪库容2050万立方米，是一个生态湿地，俗称“北湖草荡”。目前，西险大塘已先后实施加固工程，二次改造后的北湖分洪闸分洪能力由每秒315立方米提升至525立方米，为本次应急分洪提供了有力保障。
