摘要
潖江蓄滞洪区是珠江流域唯一一个国家级蓄滞洪区,在新的历史时期,改变其单一的防洪功能,进行具有调蓄洪水、降解污染物、自然观光等多功能的湿地化建设是十分必要的。提出了“三核一带”湿地化建设模式,利用现有的3个子围及新建的2座拦河闸,因地制宜建设不同类型的湿地,最大程度保留调蓄洪水能力,采用二维水流数学模型模拟分析湿地化建设对蓄滞洪功能的影响。结果表明,“三核一带”湿地化建设模式对洪水调蓄影响较小,不影响蓄滞洪功能的发挥,研究成果可供类似蓄滞洪区参考借鉴。
The Pajiang River Flood Storage and Detention Area(PRSDA)is the only national flood storage and detention area in the Pearl River Basin.It is important to change its single flood control function to a multifunctional wetland with flood regulation and storage,pollutant degradation,and natural tourism in the new historical period.In this paper,a novel wetland construction model summarized as"three cores and one belt"was proposed.This model used the three existing sub-watersheds and two new barrage gates,which can not only realize the construction of different types of wetlands according to local conditions,but also retain the maximum flood storage capacity.In addition,a two-dimensional water flow mathematical model was used to simulate the impact of wetland construction on the flood storage and detention function.The simulation results showed that this newly wetland construction model had little impact on flood storage,which guaranteed the performance of the flood detention function of PRSDA.The results can provide important references for similar research on flood storage and detention areas.
