城市近郊蓄滞洪区非洪水期调度运行管理研究--以治理深圳河第四期工程为例

摘要

针对城市近郊蓄滞洪区的功能和运行管理特点，以治理深圳河第四期滞洪区工程为例，从滞洪区地形和区域布置合理性着手，分析滞洪区与上下游河道水力高程特点，开展了非洪水期蓄水、泄水过程模型试验研究。建立了基于理想理论的湿地水体环境水体更换周期预测模型，研究多因素条件下的滞洪区湿地水体置换周期。为保障非汛期滞洪区生态湿地景观水位和良好水质状态，根据上游河道来水条件，制定了滞洪区进水闸、泄水闸调度备用运行方案。%Considering the Phase IV Training projects of Shenzhen River as a representative case study , according to the characteris-tics of function and operation management of flood detention located in suburban , approaching from the rationality on detention basin topography and regional layout , elevation relations analysis between the flood detention and up -downstream river .The storage and discharge process model test research in non -flood period.Based on the ideal theory , A prediction model for water replacement cycle of wetland was established to analyze the flood detention area under various conditions .In order to preserve landscape water level and good water quality during the non -flood season, the intake and sluice operation schemes of flood detention were formula-ted for water management departments .
