央广网南昌9月8日消息 据中国之声《央广新闻》报道,8月份以来,长江上游来水和江西全省降雨明显减少,中国最大淡水湖鄱阳湖面积不断减小。在过去一个月,鄱阳湖“瘦身”将近三分之一,专家称,有可能对湖区生产生活造成一定影响。
今年夏天,江西大部分地区都遭遇了洪水的侵袭,长江江西段、鄱阳湖水位居高不下,堤岸浸泡洪水中长达数十天。不过,自从今年的8月5日长江江西段、鄱阳湖全线退出警戒线以来,长江来水就不断减少。
江西省防总介绍,截至9月6日,长江九江站水位降幅达4.77米。8月份以来,受长江上游来水和江西全省降雨减少影响,鄱阳湖水位下降加快,鄱阳湖标志性水文站星子站水位日均降幅达到0.15米,最大降幅达0.29米,尤其是8月29日以来,星子站水位一直低于历史同期均值。
据介绍,鄱阳湖水量不断补给给长江,也是导致面积加速缩水的重要原因。据江西省水文部门推算,鄱阳湖水域面积由一个月前的3530平方公里缩减到了2380平方公里,减小了将近1150平方公里,缩水将近三分之一。湖区容积也减少近130亿立方米,累计补给长江水量达到216亿立方米。
水文部门介绍,预计未来数天,鄱阳湖水位仍将持续下降,面积也将陆续的减小,将可能影响到农业、渔业日常生产,水域植被生长以及即将到来的鄱阳湖候鸟越冬,甚至对部分城市供水和工业企业用水也会造成一定程度的影响。
