【摘要】 在太湖蓝藻暴发风险依然较高和未来规划引水量增加的背景下，摸清多年来望虞河出入太湖磷通量具有重要意义。以引江济太工程的望虞河-太湖为研究对象，计算2007年以来望虞河出入湖磷通量，以期为研究引江济太工程对太湖磷循环及水质长期影响提供关键数据。基于2007—2021年望虞河出入太湖水量数据和入湖断面水质数据计算了望虞河出入湖磷通量。结果表明，望虞河年入湖磷通量17.97～199.36 t，年均87.09 t，净入湖磷通量累计237.46 t，对受水区贡湖湾造成高磷素负荷冲击。更多还原

【Abstract】 Under the background of the high risk of algal bloom in Lake Taihu and the planned increase of water diversion in the future, it is of great significance to identify the phosphorus flux of Wangyu River to Lake Taihu water diversion. Taking Wangyu River and Lake Taihu as the research object, the phosphorus flux from wangyu River to taihu Lake since 2007 was calculated, in order to provide key data for studying the long-term effects of Jiangji-Taihu River on phosphorus circulation and water quality in Lake Taihu.The phosphorus flux of Wangyu River into and out from Lake Taihu from 2007 to 2021 was calculated based on the water quantity and quality data of Wangyu River. The results showed that phosphorus flux from Wangyu River into Lake Taihu was 17.97 ～ 199.36 t, with an annual average of 87.09 t, and the cumulative net flux was 237.46 t, causing a high phosphorus load impact on Gonghu Bay.更多还原
