摘要
由于独特的地理位置和水文气象条件,鄱阳湖区历来洪涝灾害频繁。近几十年来,受气候变化和人类活动影响,高水位洪水发生频次显著增加,2020年更是发生了超历史洪水,湖区人民生命和财产安全承受着巨大威胁。阐述了鄱阳湖区洪涝灾害情况,解析了洪涝灾害频发的原因,剖析了鄱阳湖区现状防洪体系存在的薄弱环节和短板。按照新时代生态文明建设和高质量发展要求,提出了鄱阳湖区生态防洪思路和对策建议,通过优化蓄滞洪区空间布局、创新圩垸生态防洪模式等措施,可保障今后鄱阳湖安澜、百姓安居和绿色可持续发展。
Due to the unique geographical location and hydro-meteorological conditions,Poyang Lake area has experienced frequent floods.In recent decades,due to climate change and human activities,the frequency of high flood levels in Poyang Lake increased significantly,and the"2020 flood"exceeds the highest water level in history,which put people’s lives and property under great threat.The floods in Poyang Lake area were described,and the causes of frequent floods were analyzed.The weaknesses and shortcomings of the current flood control system in Poyang Lake area were analyzed.We proposed ideas and countermeasures on an ecological way of flood control for Poyang Lake area in accordance with the requirements of fostering ecological civilization and high-quality development in the new era.The proposed measures such as optimizing the spatial layout of flood storage and detention areas,innovating ecological flood control models of polder and flood storage and detention areas to help ensure sustainable development of Poyang Lake area.
