摘　　要：蓄滞洪区对于流域防洪减灾具有不可替代的作用,现状潖江蓄滞洪区安全布局和安全设施建设短板依然突出,导致防洪运用存在启用决策困难、运用损失较大等问题,制约了防洪运用效果。为此,结合潖江蓄滞洪区各堤围防洪能力及区内社会经济情况提出布局优化方案,构建飞来峡水库-潖江蓄滞洪区防洪联合调度模型对优化前后布局方案的防洪效果开展分析计算,综合分析比较得出推荐的蓄滞洪区优化布局方案。计算结果表明:将白沙塘围与官路唇围增设为安全区可减少耕地淹没163.2 hm 2,减少洪水风险人数3002人,在有效降低潖江蓄滞洪区启用损失的同时基本不增大防洪风险。研究成果可为蓄滞洪区开展布局优化提供方法技术参考。Flood storage and detention areas play an irreplaceable role in flood control and disaster mitigation in river basins.However,the significant weakness of safety layout and safety facility construction of flood storage and detention areas in Pajiang River results in difficult decision making and great loss in flood control application,constraining the application effect of flood control.To this end,this paper proposes a layout optimization scheme by combining the flood control capability in each dike and socioeconomic conditions in the studied detention areas.Then,joint flood control and operation model related to Feilaixia Reservoir-Pajiang River flood storage and detention areas is employed to analyze and calculate the flood control effects before and after the optimized layout schemes.Finally,the recommended layout optimization scheme of the detention areas is selected by comprehensive analysis.Results show that by adding Baishatang dike and Guanluchun dike as safety areas of Pajiang River Basin,the potential inundation cultivated area decreases by 163.2 hm 2 and the number of people prone to flood risks decreases by 3002.This indicates the optimized layout scheme can reduce flood detention loss and ensure flood control safety.The results provide technical references and an approach for layout optimization of other detention areas.
