摘要

On the basis of analysis on characteristics of Meiyu and flood in 2016, total drainage volume is analyzed in details, which includes water drainage by drainage pumping on Tongyang Canal, inner canal and main irrigation canal, water drainage by coastal rivers. The characteristics of flood water drainage in 2016 are compared with 2003, 2006 and 2007. The ratio and variation regularity of self-drainage and pump drainage during the flood period in Lixiahe region is analyzed, which provides references for planning, governance and flood control.%在分析里下河地区2016年梅雨、洪水特征的基础上，对区域通扬运河、里运河、灌溉总渠3条线泵站抽排和沿海河流自排、总外排水量过程进行了详细分析，并与2003年、2006年和2007年3个典型涝水年外排水特征进行比较，分析了里下河地区洪涝期自排、抽排比例及其变化规律，为区域规划治理、防洪调度提供参考。
