中文摘要: |
单退圩是1998年洪水之后国家整治江湖的有力措施之一,已成为鄱阳湖防洪体系的一部分。2020年,鄱阳湖发生超历史记录洪水,单退圩首次大范围运用。通过回顾设立背景,分析本轮洪水的基本特点和运用实践过程,总结了单退圩取得的防洪成效,同时也揭示出单退圩存在法律地位不清、管理制度不明、未建立运用补偿机制、圩堤设置需优化、蓄排难度较大等问题。下一步应进一步调整圩堤范围,并优化运用方案,确保洪水蓄得进、排得出,探索平原蓄洪库建设,实现洪水资源化,补齐鄱阳湖应对超标准洪水短板。 |

Setting semi-restoration polder areas is one of the effective measures to renovate rivers and lakes after the 1998 flood, and has become a part of the flood management system of Poyang Lake. In 2020, a record-breaking flood occurred in the Poyang Lake region, and the semi-restoration polder areas were used on a large scale for the first time. By reviewing the background of the establishment of the semi-restoration polder areas,and analyzing the basic characteristics of the 2020 flood and application process of the semi-restoration polder areas, this paper summarizes its flood control effects, and meanwhile, reveals the problems exposed in the semi-restoration polder areas,which include unclear legal status,inadequate management system,no mechanism for the use of compensation,the need to optimize the setting of levees,the difficulties in water storage and drainage,and so on. It is suggested that the next step is to adjust the scope of the semi-restoration polder areas,optimize the application scheme,ensure that the flood water can be stored in and drained out,explore the construction of flood storage reservoirs in plain areas, realize the resource use of floods,and make up for the short board of Poyang Lake in coping with excessive floods. |
